We work across EMEA and the US fueling innovation and solving complex challenges daily. Join us to grow your skills shape bold ideas and help build the future of tech.

We are looking for a Senior Full Stack Engineer to join our dynamic R&D Team where you will own high-scale features end-to-end across our FinOps platform and AWS billing engine contributing directly to our mission of empowering fast-paced startups.

This is an agentic engineering role. It is not a traditional coding role. You will generate the vast majority of your production code with AI and your value comes from the deep technical judgment you apply on top of it: guiding the model critiquing its output and shipping solutions that are high-quality maintainable and future-proof. Were looking for someone excited that the craft of software is changing and who wants to operate at (and help define) the frontier of it.

You will work with: (NestJS Fastify Prisma ORM) React (TanStack TipTap Material UI Untitled UI) PostgreSQL.

Work location: remote from Ukraine

If you are interested in this opportunity please submit your CV in English.

• Own features end-to-end from vague stakeholder ask to production deployment including discovery design implementation testing rollout and iteration.
• Refine requirements proactively using the Value Usability Feasibility Viability (VUFV) framework. Push back on weak requirements propose better solutions than the one originally requested and keep a tight feedback loop with stakeholders.
• Generate your code with AI (we provide top-tier AI tooling currently Claude Opus 4.7 in Cursor). Your job is to direct the model review its output with a senior engineers eye and take full ownership of what ships including architecture performance security and long-term maintainability.
• Build and evolve our AI workflow dont just use it. Stay on the frontier of new models tools agents and techniques; codify what works into our setup (rules prompts tooling MCPs); and share it so the whole team levels up with you.
• Solve deep technical problems across FinOps processes and AWS billing calculations.
• Ship scalable maintainable well-tested well-documented code and create and maintain the system design and implementation docs that go with it.

• Agentic delivery is your default. You ship the bulk of your production code through AI agents and autonomous workflows while personally owning architecture performance and security.
• Youre the go-to mind on the AWS billing engine. Youve untangled the trickiest FinOps calculations and cost-optimization edge cases and teammates route hard billing questions to you first.
• You turn vague asks into the right product. Using VUFV you reshape ambiguous requests into shipped features and stakeholders trust you to push back propose better alternatives and pick the smallest thing that actually moves the needle.
• Youve delivered real end-to-end features on the stack. Multiple high-impact features across NestJS React Prisma and PostgreSQL scalable well-tested well-documented and stable in production.
• Youve raised the teams AI bar. New models agents prompts and tooling patterns you championed are now part of how the whole team works not just your own setup.
