Jobs at Djinni

About Our Client
 

Our client builds and operates GPU cloud infrastructure at the scale modern AI demands. They run dense accelerated-compute clusters on bare metal and Kubernetes, stitched together with high-performance Ethernet and InfiniBand fabrics, and deliver them to customers as reliable, secure, high-throughput platforms. They are building Cloud v2, their next-generation, clean-slate, Kubernetes-native GPU cloud, and scaling it across new data center sites. The infrastructure team sits at the center of that effort, building the systems that turn racks of hardware into a product customers depend on.
 

The role

We are hiring a Senior Observability Engineer to build the observability layer for Cloud v2. This role exists to close the single most damaging gap in our client’s current product: today their observability is reactive, so customers are their failure detector. Some of their worst incidents went undetected internally because they occurred below the layer they instrument (a corrupted forwarding entry, a flapping firewall sync process), and the customer reported the outage before their dashboards did. Cloud v2 is architected from day one against the industry’s Gold-tier bar for neocloud platforms (SemiAnalysis ClusterMAX), and proactive detection, where they see problems before the customer does, is the trust gap they are building this platform to fix.
 

You own the metrics, logs, alerting, dashboards, and detection stack that make that true. That means operator-facing observability that catches failures first and drives automated remediation, and tenant-facing observability that gives customers the usage, health, and status visibility a hyperscaler-grade cloud implies. This is the observability workstream the platform validates earliest, because detection is where the current product loses trust, and it maps directly to the ClusterMAX Monitoring and Reliability criteria.
 

This is a build-focused, hands-on senior IC role. You will spend your time engineering the telemetry pipelines, detection logic, dashboards, and alerting that turn raw signals from multi-vendor GPUs (AMD/NVIDIA), hosts, fabrics, and switches into problems we catch before customers feel them, and you will set the technical direction and standards for how we instrument the platform. You will partner closely with our client’s SRE, platform, network, and security engineers, who own the control-plane architecture, the fabric, and day-to-day operations; you own the observability that makes the whole platform legible and its failures visible.
 

What you’ll own

The OpenTelemetry foundation: own OpenTelemetry as the instrumentation standard the whole platform plugs into: the collector topology and pipelines, semantic conventions for metrics, logs, and traces, and consistent resource and tenant attribution across GPU, host, fabric, switch, and control-plane signals. Everything we instrument, internal and tenant-facing, lands on this common backbone so signals are portable, correlated, and not locked to any one backend.

Proactive detection: build the detection that fires before a customer reports, GPU failure-rate tracking, Xid detection, and the anomaly and threshold signals that feed the automated detect-drain-remediate loop, so mean time to detect stops being inverted and our client sees the problem first.

The metrics pipeline: own the metrics stack across GPU, CPU, network planes, thermal, and power (Prometheus and OpenTelemetry-based), including the DCGM profiling-metric suite (DCGM_FI_PROF_* for SM activity and tensor TFLOPs, plus PCIe AER, ECC, power and thermal, and NVLink and fabric throughput), with custom exporters and OpenTelemetry receivers where DCGM falls short.

Instrumenting below the layer we watch today: push instrumentation down into the sub-layers where our most damaging silent failures live (forwarding state, firewall and HA sync, fabric health), so the failure classes that used to reach us through the customer surface on our own dashboards instead.

Host and switch debug data: build reliable extraction of host and switch debug and telemetry data so responders have the signal they need without hand-collecting it during an incident.

Operator and tenant dashboards and alerting: build the operator dashboards and low-noise, actionable alerting the on-call team runs on, and a tenant-facing status page so customers are not our failure detector.

Tenant-scoped observability: deliver per-tenant usage and utilization visibility and per-tenant access to logs and metrics, cleanly isolated from internal ops telemetry, on a multi-tenant model where no tenant can see another’s data.

Proactive customer notifications: build automated, proactive maintenance and change notifications to affected tenants, replacing today’s manual and ad hoc comms.

Reliability and SLO instrumentation: build the telemetry behind the 99.9%+ node SLA measurement, the passive and active health-check battery, and MTTA and MTTR tracking, so reliability is measured, not asserted, and so the health automation has trustworthy signal to act on.

AI-leveraged observability: push our observability toward an AI-augmented model, agentic triage, anomaly detection, alert-noise reduction, and MCP-driven access to our operational telemetry, so a small team catches more, faster, than headcount alone would allow.

Technical direction and standards: set the instrumentation patterns, metric and label conventions, alerting standards, and SLO practice the rest of the platform adopts, and raise the bar through design review and mentorship.
 

What we’re looking for

Required

8+ years building production observability or monitoring systems at scale, ideally for cloud, hosting, or high-performance compute environments, with real platform-build experience (not solely operating dashboards someone else built).

Deep expertise with Prometheus and the metrics ecosystem: PromQL, exporters, recording and alerting rules, Alertmanager, and Grafana, used to build durable, reusable observability rather than one-off dashboards.

Hands-on experience designing and running OpenTelemetry as a foundational instrumentation layer: the Collector, receivers and exporters, semantic conventions, and vendor-neutral pipelines that multiple backends and teams plug into.

Experience running time-series at scale, including long-term and high-cardinality storage (Thanos, Mimir, Cortex, or VictoriaMetrics), and a real understanding of cardinality, retention, and query-performance tradeoffs.

A track record of building alerting that is actionable and low-noise, and of practicing SLO and error-budget-based reliability rather than alert on everything.

Strong programming skills in a real language (Python, Go, or similar) used to build maintainable exporters, collectors, and observability tooling, not just glue scripts.

Strong Linux systems fundamentals: you can reason about the OS, networking, storage, and the boot and provisioning path, and instrument at that level, not just at the application surface.

A track record of owning significant observability systems end to end and setting technical direction that other engineers adopt: defining standards and influencing architecture across a team.

A demonstrated bias toward building things right the first time: reproducible, code-defined observability and sound instrumentation design over short-term shortcuts.

Strong written communication: you document designs and decisions clearly, and you raise the team’s bar through design review and mentorship.
 

Strongly preferred

Multi-vendor GPU/HPC observability: DCGM & dcgm-exporter (NVIDIA) and RDC & AMD Device Metrics Exporter (AMD/ROCm); NVML and AMD SMI; Xid vs. amdgpu/RAS error reporting; DCGM_FI_PROF_* and ROCProfiler profiling metrics; GPU node health checks (DCGM diagnostics, AGFHC, ROCm Validation Suite).

Experience building multi-tenant, tenant-facing observability with per-tenant metric and log isolation.

Checkmk (our client runs parent and child sites today), and experience migrating or bridging a Checkmk estate into a modern metrics stack.

Network and fabric observability: switch telemetry, streaming telemetry (gNMI) and SNMP, BGP and fabric health, and RoCE Ethernet or InfiniBand/UFM fabric monitoring.

Log and trace pipelines and distributed tracing: Loki, Elastic, or Vector, and instrumenting traces across a distributed control plane.

Kubernetes observability: kube-state-metrics, cAdvisor, and GPU Operator metrics, in a multi-cluster environment.

Status-page and incident tooling, MTTA and MTTR instrumentation, and integration with an incident-response and paging workflow.

Building observability within a SOC 2, ISO 27001, or HIPAA compliance posture, including audit-log export.
 

How we work

Small, senior, high-trust teams. We hire people who can own and solve problems end to end and we give them the room to do it.

Code over clicks. The platform is defined, reviewed, and versioned. Manual changes are the exception and they get automated away.

Build it right. We invest in sound architecture and durable design so the platform scales cleanly instead of accumulating debt.

Customers are real. The platform exists to serve customer workloads, and we build to the reliability and self-service standard a hyperscaler-grade cloud implies.

We document. Designs, decisions, and architecture are written down so the team compounds knowledge instead of re-learning it.
 

AI as a force multiplier

We expect our engineers to use AI to move faster and operate at higher leverage, and we build our environment to make that the default rather than an afterthought. We maintain CLAUDE.md and AGENTS.md context files across our repositories, run MCP servers against our operational systems (Jira, NetBox, Checkmk), and use agentic coding tools such as Claude Code directly in our infrastructure and platform workflows.
 

For this role in particular, observability is one of the highest-leverage places to apply AI: anomaly detection, automated incident triage, alert-noise reduction, and AI-assisted root-cause analysis over the telemetry you build. You don’t need to be an AI expert, but you should be eager to fold these tools into how you design and operate observability, and to help us define what an AI-leveraged infrastructure team can do.

What success looks like
 

First 30 days

Ramped on the Cloud v2 architecture, the current observability stack (Prometheus, Checkmk parent and child sites, and the GPU and fabric telemetry), and the lab, and able to navigate the repos and design docs independently.

Shipped your first meaningful contribution to the metrics, alerting, or detection stack with the team’s review.

Aligned with SRE, platform, network, and security on where your work meets theirs and on the highest-value detection gaps to close first.
 

First 90 days

Owning a defined area of the v2 observability layer end to end, from design through delivery (for example the OpenTelemetry instrumentation foundation, the GPU and DCGM metrics pipeline, the alerting and SLO framework, or the tenant-facing dashboards and status page).

Delivered proactive detection for at least one failure class that the platform previously learned about from customers, so our client now detects it first.

Measurably reduced alert noise or improved mean time to detect for a meaningful part of the fleet.
 

First 12 months

The go-to engineer for the hardest observability and detection problems in Cloud v2, trusted across SRE, platform, network, and security, and setting the standards the team instruments by.

Designed and delivered a significant piece of the platform’s observability (proactive detection, tenant-facing observability, or reliability and SLO instrumentation) that raised the whole team’s leverage and moved the platform toward its Gold-grade Monitoring and Reliability bar.

  If this sounds interesting and close to what you enjoy doing, feel free to reach out. We’d be happy to get to know you and share more about the product, team, and role.

Imagine joining a startup at the very beginning - founded by Ukrainians in Silicon Valley, backed by global investors, building AI that's rewriting how a $7 trillion industry works. Superagent AI is creating the world's first autonomous AI sales agent - an AI that listens, learns, and coaches humans to sell better than ever before. 

We're already working with top U.S. insurance networks - and we're just getting started.

We're looking for two or three QA Engineers to be the quality backbone across both customer deployments and product development. You will work with our product team to test new features before they ship. Part of this role is testing AI voice agents, actually calling them, listening to how they respond, and catching issues with tone, timing, and conversational flow.

The Role: QA Engineer

You will:

• Help establish QA processes and standards as the team grows - you'll be the first dedicated QA in the team
• Test new product features alongside the engineering team - both UI and backend
• Test customer deployments end-to-end before launch: make live test calls to AI voice agents, verify call flows, check inbound/outbound campaign configurations
• Evaluate voice agent quality - pronunciation, response timing, conversation logic, objection handling, edge cases (background noise, interruptions, unexpected questions)
• Identify, document, and track bugs in Linear with clear reproduction steps and call recordings where relevant
• Build and maintain test scripts and checklists for repeatable customer launch QA
• Build AI Agents that will do all the work you don't like :)
   

This is a creative, technical, and analytical role.

What We're Looking For

We don't care about your degree. We care about your hunger, brains, and curiosity.

You might be the right person if you:

• 3+ years in QA, testing, or a similar role
• Strong attention to detail and a natural instinct for finding edge cases
• Comfortable testing conversational AI - you'll spend a meaningful part of your day talking to voice agents and evaluating their responses
• Good spoken English (B2+ level) - you need to test English (Spanish) - speaking voice agents and spot when something sounds off
• Familiar with bug tracking tools (we use Linear)
• Self-organized and able to juggle multiple testing streams - customer launches and product releases often happen in parallel
   

Bonus points for:

• Experience testing voice, telephony, or conversational AI products
• Scripting skills (Python, JS) for test automation down the road
   

Why You'll Love It Here

Real mentorship - You'll work directly with our founders:

• Vlada Lotkina (Wharton MBA, 8-figure exit, ex-BCG & Dell Strategy)
• Vadym Shashkov (AI engineer, YC alum, built 70+ mid-large-sized projects and managed large teams)
   

You'll learn more in 3 months here than in 3 years anywhere else.

• Global exposure - Build AI that's being deployed across the U.S. and Europe.
• Ownership & trust - You'll make real decisions, not PowerPoints.
• Flexibility - Work remotely, but think globally.
• Competitive pay with performance-based bonuses.

What Makes This Special

This is not a "prompt engineering internship". This is your chance to help train the mind of an AI that will transform how millions of people work. 

If you're the type who's constantly curious, relentlessly improving, and deeply proud of your craft, you'll thrive here.

Talk to German-speaking companies about Tender Navigator, help start new conversations and learn how B2B SaaS sales and business development actually work. No sales experience needed - we will teach you.

The role

We are looking for a German-speaking intern who enjoys talking to people and wants to learn how a B2B software company finds and wins its customers. This is a first job in tech, not a senior sales position - if you speak German, are proactive and want to learn, we can teach you the rest.

You will help us reach German-speaking companies and partners, start conversations, introduce what Tender Navigator does and spot the ones worth following up. Nobody will hand you a script and a target on day one: you will learn the product and the market with the team, and take on more as you get comfortable.

We are a small team, so your work is visible from week one and you get to see the whole picture - how a message turns into a conversation, a conversation into a demo, and a demo into a customer.

Languages

Fluent or strong German is the one thing we cannot teach you - you will be writing to and speaking with people in German-speaking markets.

Ukrainian at native level and English at a good working level are needed for day-to-day work with the team.

You do not need business or sales German. Clear, confident, natural German is enough.

What you will be doing

• Getting in touch with German-speaking companies and potential partners.
• Starting conversations and introducing Tender Navigator in plain language.
• Helping spot companies that could genuinely benefit from the product.
• Supporting the team through the business development and sales process.
• Keeping your outreach and conversations organised so nothing gets lost.
• Passing on what you hear from the market to the product and marketing teams.
• Learning how B2B SaaS sales and business development work in practice, with the team.

What we are looking for

Genuinely short list. Sales experience is not on it, and not having any will not count against you.

• Fluent or strong German.
• You enjoy talking to people and are comfortable starting a conversation.
• Active, energetic and proactive - you do not wait to be told what to do next.
• A real willingness to learn.
• Responsible, and able to organise your own work without someone checking on you.

What you will learn

• How a B2B SaaS company finds, qualifies and wins customers.
• How to open a conversation with a company that has never heard of you.
• How to listen for a real business problem behind a polite answer.
• How the tendering and public procurement market works, and who buys in it.
• How to work with modern sales and outreach tools - we will show you the ones we use.

This is a good fit if you are

• A student or a recent graduate looking for a first real role.
• Curious about startups, SaaS, sales or business development.
• Good with people and with words, with no formal sales background at all.
• Looking for a place where you will learn quickly and see the results of your work.

Nice to have, definitely not required

• Any experience talking to customers - retail, hospitality, support, volunteering, student societies. It all counts.
• An interest in technology, startups or how businesses buy software.
• Studies in business, economics, communication, languages or something adjacent.
• Other languages on top of German.

We are an IT services company based out of San Francisco, USA. ​​We build and acquire expert engineering teams to help our clients meet their business needs and solve their operational challenges.

We are looking for a Senior Software Engineer for long-term contract work to join one of our client’s Development Product Teams. This is a hands-on engineering role. You will write the code, review it, deploy it, and be on the hook when it misbehaves. There is no layer between you and production, and no layer between you and the people who depend on the platform.

This position may require working between the hours 12:00 PM to 8:00 PM Kyiv time. 

Tech Stack: 

• Backend: C# / .NET (ASP.NET Core Web API), Entity Framework, xUnit, REST APIs
• Azure: App Service and deployment slots, Azure SQL, Redis, Key Vault, Functions/WebJobs, Service Bus, Event Grid, Application Insights / Log Analytics, Azure DevOps pipelines
• Edge: Cloudflare (WAF, Workers, cache and redirect rules)
• Integrations: Salesforce (REST and SOAP APIs, OAuth, Connected Apps), OIDC-based member identity, learning and event platforms
• AI & Developer Tooling: GitHub Copilot, ChatGPT, Claude, or similar AI-assisted development tools

Requirements: 

• 8+ years building and running production C#/.NET web applications and APIs, including ownership of what you shipped.
• Strong, current Azure experience as a developer who operates their own environments: App Service and slots, Azure SQL, Key Vault, managed identities, and diagnosing problems from logs and metrics rather than guesses.
• Comfort in a small team with a wide surface area: you can pick up unfamiliar code, work without a spec, and ask the sharp question early.
• Must have experience applying AI within development. More detailed experience with AI-Native development and AIDLC preferred.

Would be Preferred:

• Azure DevOps (or comparable) pipelines — you have built and fixed CI/CD, not just pushed the button.
• Integration work against third-party SaaS APIs — OAuth flows, rate limits, sandbox data, and the failure modes that only appear in production.
• Salesforce platform integration experience (Connected Apps, client-credentials OAuth, staging test data).
• Automated testing as a habit, not a phase: unit, integration, and end-to-end, and the judgement to know which one a given risk deserves.
• Microsoft Azure certification — Azure Developer Associate (AZ-204) or a comparable Azure credential.

About iSpeedToLead

iSpeedToLead is a two-sided real estate lead marketplace operating across the United States. Sellers of motivated-seller leads list on one side, and real estate investors buy on the other. We are a bootstrapped, profitable product company with an engineering and analytics team that ships fast and makes decisions from data rather than opinion.

About the role

This is the first dedicated Customer Success hire at iSpeedToLead. Today, buyers are supported reactively: tickets get answered, credits get issued, and nobody owns what happens to an account between its first purchase and its last one.

You will own the post-purchase relationship with our buyers. That means onboarding them properly, keeping high-value accounts healthy, and turning churn from something we observe into something we manage. You will build the function itself (playbooks, health scoring, reporting) rather than inherit it.

One thing worth stating openly before you apply: the workload is around 50 hours a week for the first 6 to 9 months while the function is being built. We would rather you decline now than discover it in month two.

Key responsibilities

Onboarding and activation

• Own the onboarding of new buyers end to end, from first purchase to first repeat purchase.
• Run onboarding calls and follow-ups, making sure every new buyer understands how to filter, buy, and work leads effectively.
• Design and maintain the onboarding sequence (content, timing, channel) and improve it based on what actually converts.

Account health and retention

• Manage a book of high-value accounts with regular check-ins, usage reviews, and proactive outreach.
• Build and maintain a health-scoring model that flags at-risk accounts before they churn, not after.
• Run save conversations on at-risk accounts and document what worked, by reason code.

Escalations and problem-solving

• Act as the escalation point for buyer complaints, including lead quality disputes, refund requests, and billing or balance issues.
• Coordinate with support, sales, and engineering to resolve issues, and follow through until the customer confirms resolution.
• Operate within agreed refund and credit authority limits, and defend those decisions with data.

Voice of the customer

• Collect, categorise, and quantify churn and refund reasons, turning anecdotes into a ranked list.
• Deliver a weekly written report to product and leadership on retention performance and the top issues driving cancellations.
• Advocate for the product changes that would remove recurring causes of churn.

Process and reporting

• Build the Customer Success playbooks from scratch: onboarding, save, win-back, and escalation.
• Maintain accurate account records and interaction history in our systems.
• Report on retention metrics weekly, and own the definitions behind them.

Collaboration

• Work daily with sales on the handoff of new buyers, and with support on ticket patterns.
• Partner with product and analytics on lifecycle experiments and instrumentation.

Requirements

• 2+ years in Customer Success, Account Management, or Retention in a high-volume, low-ACV environment such as a marketplace, self-serve SaaS, or transactional product with hundreds of accounts. (Enterprise CSM experience with a handful of large logos is a different job and will not transfer well here.)
• Demonstrated ownership of a retention, churn, or repeat-purchase metric. You can describe what it was, what you changed, and what it became.
• Comfortable working with data: SQL basics or strong BI fluency (Amplitude, Metabase, Looker, BigQuery, or similar). You pull your own numbers rather than requesting them.
• Experience building a process from zero, such as an onboarding flow, a save playbook, or a health-score model. Executing someone else's process is not the same thing.
• Written and spoken English at C1 level, customer-facing, at volume.
• Confident on the phone with US small-business customers. Our buyers are real estate investors: direct, busy, and blunt.
• Practical use of AI tools in your daily workflow (call summarisation, drafting, triage) with examples you can show.
• A minimum of 4 hours of daily overlap with US Eastern Time.

Nice to have

• Experience in real estate, proptech, lead generation, or a marketplace with wallet or prepaid-balance mechanics.
• Familiarity with Intercom, HubSpot, or a comparable CRM and support stack.
• Experience designing lifecycle email or automation flows.
• Ukrainian or Russian in addition to English.

What we offer

• Full ownership of a metric that shows up directly in the P&L, with no layer between you and leadership.
• A greenfield function. You design how Customer Success works here.
• Real data infrastructure and an AI-native team, so arguments get settled with numbers and tooling is not a fight.
• A clear 12-month growth path to Head of Retention or Head of Customer Success, including automation of the low-touch tier and one to two direct reports.
• Remote work with flexible hours inside the required US overlap.
• Referral bonus of USD 3,000 after probation for anyone you bring in.

About the role

We build software for commercial real estate lenders, loan origination, servicing, document extraction and financial analysis.

The product is AI-heavy, and so is the way we build it.
 

This role owns the delivery cycle: sprint planning, requirements on the wiki, tickets, testing, design review. What makes it different is the method. You will not write forty tickets by hand or click through regression tests manually. You will build and run agents that do the first pass, and your value is in the specification you give them and the judgment you apply to what comes back.
 

We are looking for someone who has already worked this way, or who will obviously thrive doing so.
 

Schedule: read this first
This role bridges a development team in Europe and a business team in the US. Two fixed daily commitments:
10:00–12:00 Kyiv time — morning call with the dev team, Monday–Friday
 

19:00–21:00 Kyiv time — call with the US team, Monday–Friday
 

Both are fixed, five days a week. The hours between are yours to structure, and the split is real, plan for it rather than discovering it in month two. Apply only if this works with your life long term.

What you'll own
- Sprint management
- Create and run sprints; manage planning, scope and capacity
- Keep the backlog groomed and prioritized with engineering and leadership
- Requirements and documentation
- Write feature descriptions and specifications on the wiki
- Keep wiki, designs and tickets consistent with each other
- Tickets
- Create Stories and Bugs in the team's required format, with clear acceptance criteria
- Build reusable agent workflows that produce tickets to standard instead of drafting each from scratch
- Testing
- Write and execute test plans; run regression passes before release
- QA AI extraction output against source documents and file defects with the source evidence
- Design
- Review implementation against Figma designs and flag mismatches before they reach release
- Catch gaps between design, spec and built behavior
- Product development
- Participate in scoping and design discussions; represent the user in build decisions


What we're looking for
-3+ years in product management, delivery management, or a PM/QA 
-AI is already how you work, not a tool you occasionally open, you can walk us through your daily setup and what it replaced
-Hands-on with agent workflows: Claude Skills, MCP / tool use, Claude Code, Cowork or comparable frameworks
-You can write a specification precise enough that an agent produces usable output from it — the same skill that makes a good ticket
-Judgment about where AI output needs verification, and the discipline to actually verify it
-Comfortable with messy documents and structured data, spreadsheets, PDFs, extraction schemas
-Strong spoken and written English and Russian, you run calls in both, daily
-Able to commit to the fixed call schedule above on an ongoing basis
Familiarity with Jira, Confluence and Figma
 

Nice to have
-Commercial real estate, lending, fintech or insurance domain experience
-QA background, manual or automated
-SQL, or enough Python to inspect data and prototype
-Experience with document-heavy B2B workflows
 

How we work
-Tooling is paid for and expected to be used daily
-Small teams, short release cycles, direct access to customers
-Two fixed daily calls (see Schedule); everything else is async and flexible
-You are the connection point between the dev team and the US business team

About the Role

We’re a lean product team developing a consumer commerce platform that combines real-time 3D interactions with the purchase of physical products. The product also includes a real-money wallet and operational workflows for order processing and fulfillment.

Our technology stack is built entirely around TypeScript. The engineering team is small and experienced, with engineers working closely with and reporting directly to the CTO, allowing for fast communication and decision-making.

We’re looking for a Senior Mobile Engineer to lead the development of a native mobile application for an existing consumer product with rich, real-time 3D interactions.

You’ll take ownership of the React Native application from initial architecture through production release on both iOS and Android. A major part of the role will be translating an existing interactive web experience into a smooth native product, including animations, gestures, and platform-specific functionality.

This is not a mobile-only position. Engineers are encouraged to own features end to end, including the supporting APIs, asynchronous processing, and database changes. The backend is built with Node.js and TypeScript, so experience working beyond the mobile layer is highly valued.

What You'll Do

• Design and develop the mobile application using React Native, Expo, and TypeScript, from initial setup through App Store and Google Play releases.
• Build high-quality animations and gesture-based interactions using tools such as Reanimated, Gesture Handler, and Skia, with a strong focus on smooth performance.
• Implement payment functionality, wallet-related experiences, and reliable synchronization between client-side state and backend financial records.
• Work with native functionality when required, including push notifications, secure storage, media playback, deep linking, and platform-specific payment integrations.
• Own features across the stack when needed: define API contracts, develop Fastify endpoints and background processes, implement the mobile experience, and add appropriate monitoring and instrumentation.
• Establish and maintain the mobile delivery process, including builds, signing, store submissions, OTA updates, and crash reporting using EAS, fastlane, or similar tooling.

What We're Looking For

• 5+ years of professional mobile development experience, including at least 3 years working with React Native applications released to production.
• Strong TypeScript skills and practical familiarity with Swift and/or Kotlin for debugging, understanding native issues, and implementing platform-specific functionality when necessary.
• Hands-on experience building complex mobile animations and gesture-driven interfaces.
• Understanding of mobile performance and the ability to create responsive, smooth user experiences.
• Practical backend knowledge, ideally including Node.js APIs, relational databases, and asynchronous processing or message queues.
• Ability to take ownership of features beyond the mobile interface and contribute to their server-side implementation is strongly preferred.
• Experience with payments, digital wallets, or other transaction-heavy consumer applications is a significant advantage.

Nice to Have

• Experience with mobile 3D technologies such as Three.js, react-three-fiber, SceneKit, or GPU-accelerated Skia.
• Experience handling complex video and media playback scenarios on mobile.
• Previous experience transforming an established web product into native iOS and Android applications while maintaining a consistent product experience.

We’re looking for a Full-Stack Engineer to work across a customer-facing web application, internal operational tools, and the Node.js services supporting both.

The scope is varied: you might build a new feature for the customer-facing React application together with the required API and data model, then move on to an internal workflow that improves operational efficiency or a background process handling inventory-related data.

The engineering team has a thorough code-review culture, with senior engineers actively reviewing pull requests and maintaining a strong focus on testing, code quality, and continuous improvement.

What You'll Do

• Develop end-to-end product functionality using React 19, Vite, TanStack Query, CSS Modules, Node.js/Fastify, PostgreSQL, and RabbitMQ.
• Build and improve internal operational tools covering areas such as catalog management, orders, fulfillment, and financial workflows.
• Create and maintain shared API contracts using Zod schemas to keep frontend, backend, and worker services aligned.
• Write automated tests alongside development using Vitest for unit/component testing and Playwright for important end-to-end scenarios.
• Take part in code reviews, technical discussions, and post-incident analysis.
• Take ownership of the features you build through deployment and production operation.

What We're Looking For

• Around 3–5 years of professional full-stack engineering experience.
• Experience with TypeScript is preferred, although engineers coming from .NET or Java with solid frontend experience are also welcome.
• Good knowledge of modern React, including hooks, rendering behavior, state/data-fetching patterns, and component lifecycle.
• Practical experience developing server-side APIs and working with relational databases and SQL.
• Ability to design database tables, write efficient queries, and understand indexing fundamentals.
• A quality-focused approach to development, including testing your own work rather than treating testing as a separate final step.
• Clear and pragmatic communication and the ability to collaborate effectively through code reviews and technical discussions.

Nice to Have

• Experience with message queues or brokers such as RabbitMQ.
• Familiarity with Redis or similar caching technologies.
• Experience with Drizzle or another strongly typed ORM.
• Hands-on Playwright experience, including more complex scenarios beyond basic happy-path testing.
• Interest in 3D, animation, or visually creative frontend development.
