Jobs at Djinni

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
 

What we offer
-[Employment type — contract / EOR / full-time]
-[Benefits, equipment budget, learning budget]

• 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.

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.
• Provide technical leadership for the internal operations platform supporting catalog, fulfillment, finance, and customer-support workflows.

• 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.

We are looking for an AI-First Golang Team Lead for one of our product engineering pods: a hands-on engineer who uses AI to ship fast and acts as the face of their pod towards clients and leadership.

⚠️IMPORTANT: This is not a traditional coding role. You’ll use Claude Code and other AI tools to 10x your output, always thinking about how the product or feature you are working on benefits the user. Also: we have no QA team, you OWN the quality of what you ship!

🧭About this role: every engineer on the team already owns their work end-to-end (IC + DRI). Everyone in the pod is, in effect, their own architect and lead developer. So this role is not about being the strongest techie in the room or telling people how to build.

A Team Lead is the spokesperson, coordinator, and facilitator for their pod, internally with product, design, and leadership, and externally with clients. You come from the management path, not the deep-specialist path: you have seen a lot as a developer and have consciously decided that enabling a team, working with clients and driving product outcomes is what energizes you now, not coding all day.

You remain a hands-on engineer. Expect roughly 30-40% of your week on coordination, client and product work, and the rest as an individual contributor. This is not an HR-style people-management role: no performance reviews, no career coaching. As we scale, light one-on-ones and check-ins may become part of it, but the job is coordination and delivery, not administration.

🧑 💻 What you’ll actually do:

• Be the spokesperson for your pod, internally with product, design, and leadership, and externally with clients and partners.
• Coordinate work across the pod: break initiatives into chunks, sequence them, surface blockers, and facilitate hand-offs (lightweight project management; we deliberately have no project managers).
• Gather client requirements first-hand and funnel them straight into the pod so nothing gets lost in translation.
• Represent your pod in product planning sessions and bring a strong product-driven point of view to scoping and trade-offs.
• Help pod members with product decisions and prioritization, enabling engineers who may be technically stronger than you.
• Contribute hands-on as an engineer: own features end-to-end, use Claude Code to generate Golang backend code, review AI output for quality and architectural fit.
• Join client meetings to align on requirements, report on delivery, and keep the relationship professional and calm.

📚 Our stack:

• Backend: Go monorepo (no framework, 3+ services).
• Hosting: PaaS-managed containers; local setup fully mirrors production via Docker Compose.
• Tools: Jaeger tracing, Betterstack (Logging, Alerting), Redis Asynq queue.
• Databases: PostgreSQL, Redis.
• AI tooling: Claude Code (mandatory).

🚢 Products you will lead a pod on:

• An AI search & recommendation engine for major travel enterprises: heavy client integration work (SSO, security reviews, GDS integrations) with demanding enterprise customers.
• A content enrichment API: high-scale, data- and AI-focused backend work.
• Partner and supplier integrations, data ingestion pipelines, LLM providers.

✅ You must have:

• 2-3+ years of technical leadership experience leading a team, squad, pod, or similar unit (a hard must; think team lead or early-stage engineering manager).
• A developer’s background (minimum 5 years): you have seen production reality with your own hands before moving towards leading people.
• A genuinely product-driven mindset: you think about user value and business outcomes before implementation.
• Comfort facilitating and coordinating a pod without relying on formal authority.
• Willingness and ability to take part in client meetings and act as the external face of your pod.
• Excellent spoken and written English for planning sessions, stakeholder updates, and client conversations.
• Ownership mentality with a strive for elegantly simple, high-quality solutions; you test your own work thoroughly since we have no QA team.
• Proven experience using Claude Code; share specific examples.
• Solid Golang experience; you’ll review AI’s code, and you must understand how it works.
• Ability to do on-call once in a while to help maintain our platform’s reliability & uptime.
• ⚠️ European or African timezones (±3 hours from CET).
• Available full-time (40 hours/week).

❤️ You are a great fit if you:

• Made the classic developer’s fork-in-the-road decision: lifelong engineer or leading people, and chose people, clients, and product.
• Are energized by product planning sessions and have opinions about what the pod should build next, not just how.
• Are comfortable being the face of your pod, in internal planning rooms and on calls with enterprise clients.
• Enjoy enabling engineers who are technically stronger than you.
• Ship fast but always verify it actually works; think “how can AI build this?” as your first instinct.
• Get frustrated when development takes weeks instead of days.

‼️Things to consider before applying that won’t be a match:

• This would be your first leadership role.
• You see the lead as the chief architect who makes the technical decisions for the team.
• You are looking for an HR-focused people-management role built around performance reviews and career coaching.
• You want to lead a team without staying hands-on in the codebase.
• You would rather not take part in client meetings or stakeholder-facing conversations.
• You prefer to focus on execution and leave product planning to others.
• You rely on formal authority to get a team moving.
• You have never used Claude Code or similar AI coding tools.
• You are outside European/African timezones.
