Senior Software Engineer (all genders)

ABOUT THE ROLE You'll join our Lisbon engineering hub as a Senior Software Engineer and own real features end to end, from the UI a user touches to the API, the data, and the deploy. You'll be one of the people deciding how AI and agentic systems actually show up in what we ship, not in a demo, but in live client and internal delivery. This is a hands on senior role with genuine ownership: less waiting for tickets, more taking a problem and shipping the answer. The Team Lead seat for our engineering track is currently open, so you'll have direct access to the Practice Lead and unusually high autonomy from day one. If you want to build cool things with LLMs and agents and see them used in production, and you want to set the technical bar for a growing hub rather than slot into someone else's, this is that seat. WHAT YOU'LL DO - You'll ship AI powered fullstack features and internal tools end to end, owning frontend, backend, data, and deployment - You'll build with LLMs and agentic frameworks and make them reliable enough for live client and internal delivery, not just prototypes - You'll raise the engineering standard of the Lisbon team through code review, testing, and CI/CD that people actually adopt - You'll cut delivery and QA cycle time by automating the slow, manual parts of how we work - You'll review critical pull requests and unblock the engineers around you - You'll contribute reusable components and shared libraries that the rest of the team builds on - You'll become the technical reference point for AI augmented engineering in the Lisbon hub WHAT YOU BRING Must-haves - 5+ years building production software across the full stack, with features you personally owned from empty repo to live - Strong TypeScript and React on the frontend, and Node.js or Python on the backend - Real, shipped experience with LLM APIs and at least one agentic framework: prompt design, tool calling, retrieval, and handling failure modes - A shipping bias: you deliver working incre
