Jobs at Djinni

Location - Remote (UK-based) 
Reports to[CTO / Head of Engineering
 

About the Project:

It is a mobile accounting app for sole traders, freelancers and self-employed workers — income, expenses and tax handled from a phone in minutes rather than evenings.

Behind a simple app sits the complicated part: bank feeds that stop syncing, receipts that scan wrong, subscriptions that don't renew, a figure that's off by £40 and nobody can say why. That's your side of the house. When a user's tax number looks wrong, someone has to prove what actually happened — in the data, not in the conversation.

The job in one line

You are tier 2: everything customer support can't resolve stops with you, and everything Engineering shouldn't be interrupted by stops with you too.

What you'll do

- Own tier-2 escalations end to end. Take what front-line support can't close, investigate it properly and either fix it, work around it, or hand Engineering a ticket they can act on immediately. Target: [90%] of escalations resolved or reproduced within 1 working day.
- nvestigate in the data, not by guesswork. Read logs, trace requests, query the database (read-only SQL), check API responses and reconcile what the app displayed against what was actually recorded. Every escalation you pass on carries a clear reproduction path and evidence.
- Run bank feed and integration failures. Open Banking connections drop, banks change formats, tokens expire, third-party providers have outages. You own diagnosis, the vendor conversation, and the honest message to affected users.
- Triage mobile crashes and releases. Monitor crash and error reporting, spot regressions after a release before the reviews do, and verify fixes on real devices across iOS and Android versions.
- Own billing and store issues. Failed payments, App Store / Google Play subscription problems, duplicate charges, refunds, entitlement mismatches — resolve them and reconcile with Finance.
- Manage incidents. Be the person who declares one: assess impact, notify users and the team, keep the status page current, coordinate to resolution, then write the post-incident review with a root cause and actions that actually get done.
- Cut the ticket volume at source. Turn recurring escalations into permanent fixes: bug reports Engineering prioritises, product changes, internal diagnostic tooling, and written playbooks that let tier 1 handle the case themselves next time. Success looks like fewer escalations reaching you each quarter, not more.
- Handle deadline peaks. Late January Self Assessment, the 5 April year end and quarterly VAT/MTD deadlines turn every technical fault into an urgent one. Cover, monitoring and rollback plans get agreed before those windows, not during.
- Guard data and access. Verify identity before touching an account, work under UK GDPR with financial and personal data, keep production access to what your role requires, and escalate suspected security or data incidents immediately.

 What we're looking for

- 3+ years in technical support, application support or a tier-2/escalations role for a live software product — ideally consumer-facing.
- You can read a log, write a SQL SELECT, call an API endpoint with Postman / curl and inspect a JSON response without help.
- Practical experience with bug triage alongside an engineering team: severity, reproduction, prioritisation, verification.
- Experience with third-party integrations or API failures, and dealing directly with vendor support.
- Written English clear enough to explain a technical cause to a user in plain terms and to a developer in precise ones.
- Calm and methodical during outages — no panic, no guessing, no silence.
 

Nice to have

- Fintech, accounting, payroll or payments background — bank feeds, Open Banking, reconciliation, double entry.
- Mobile support experience: crash reporting, device fragmentation, store release cycles, RevenueCat or similar subscription tooling.
- Scripting for diagnostics or reporting (Python / SQL / Bash).
- Experience setting up monitoring, alerting or an internal admin/diagnostic tool.
- Any incident-management framework in practice, on-call rotations, blameless post-mortems).

What we offer

- £20 000 plus a bonus.
- A function you own and build, with the tooling budget and production access to do it properly.
- Remote  working with core hours 09:00–18:00 UK. On-call is limited to release windows and tax-deadline peaks, compensated at rate.
- Annual leave plus UK bank holidays, with peak-season cover agreed in advance.
- Direct line to Engineering — your bug reports go into the sprint, not into a backlog nobody reads.
- Tools and training funded, including certifications relevant to the role.

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.

Let’s foster the world together!

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.

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’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.

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 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.

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 highly experienced individual contributor to take technical ownership of backend architecture across a customer-facing web product, an internal operations platform, and the supporting services.

A key part of the role involves systems where correctness and reliability have direct financial impact, including wallet and ledger functionality, transaction settlement, verifiable outcome generation, and fulfillment workflows.

The platform follows an event-driven architecture within a TypeScript monorepo. It includes separate Fastify BFF services for customer and administrative applications, asynchronous workers, and shared domain components backed primarily by PostgreSQL. MongoDB supports analytics use cases, Valkey is used for caching and presence, RabbitMQ handles messaging, and S3-compatible storage with CDN delivery manages object distribution.

The infrastructure runs on AWS ECS with infrastructure-as-code and automated CI/CD. You’ll work closely with the CTO on architectural direction and the continued evolution of the platform.

What You'll Do

• Take ownership of architectural decisions across backend services, including service boundaries, data ownership, idempotency, outbox patterns, caching, and failure handling.
• Document important technical decisions and revisit them as requirements and system constraints evolve.
• Design and evolve financially sensitive functionality, including double-entry wallet accounting, payments and withdrawals, inventory settlement, and auditable outcome-generation mechanisms.
• Work across layers when necessary, from database schemas and Drizzle migrations through domain logic, Fastify APIs, asynchronous consumers, and React interfaces.

• 8–9+ years of professional software engineering experience, including several years with direct responsibility for architecture and technical decisions in production systems.
• Proven experience defining service boundaries, selecting appropriate storage technologies, and scaling production systems.
• Practical understanding of capacity planning, caching strategies, database connection management, performance bottlenecks, and production debugging.
• Ability to evaluate architectural trade-offs such as consistency vs. availability, synchronous vs. asynchronous communication, caching vs. source-of-truth access, and build vs. buy decisions.
• Strong server-side engineering background with Node.js/TypeScript, .NET, or Java. Engineers coming from .NET or Java should be comfortable transitioning to TypeScript.
• Deep experience with relational databases, including schema design, transactions and isolation levels, indexing, and migrations of live production systems.
• Experience using document databases and caching systems where they provide clear advantages alongside relational storage.
• Production experience with event-driven architectures, message brokers, idempotent processing, outbox patterns, and delivery guarantees.
• Experience owning financially sensitive systems such as payments, billing, ledgers, trading, or similar transaction-heavy functionality.
• Ability to document architectural decisions clearly and challenge technical assumptions when necessary.

Nice to Have

• Experience with AWS ECS, infrastructure as code, and GitHub Actions-based CI/CD.
• Experience with CDN infrastructure and object storage at scale.
• Background in regulated or compliance-sensitive consumer products such as fintech, real-money gaming, or marketplaces.
• Experience managing developer experience and tooling in large monorepos using technologies such as pnpm workspaces or Turborepo.
