Lead Full Stack Engineer w Kraków, Polska

Choosing Capgemini means choosing a company where you will be empowered to shape your career in the way you’d like, where you’ll be supported and inspired by a collaborative community of colleagues around the world, and where you’ll be able to reimagine what’s possible. Join us and help the world’s leading organizations unlock the value of technology and build a more sustainable, more inclusive world. 

Your role

This is not your typical engineering role.

We’re looking for a Full Stack Lead Engineer to our group wide enterprise platform NEO, who doesn’t just write code, but thinks in systems, builds fast, and helps shape the future of both product and team. You’ll partner closely with the Global Product Design Director to define what’s next. 

This isn’t just code. It’s architecture, product thinking, challenging the status quo, problem framing, fast iteration, and building systems that scale with intelligence and intent. It’s about leading the charge in building something that actually matters. It’s ambitious. The vision is clear, but there's ambiguity too — and that's where you thrive.

Neo is an internal AI platform for Capgemini employees that help to find relevant information in knowledge bases, perform specific actions in internal systems (for example requesting a day off) or solving business problems via connecting to custom programming interfaces (APIs). The mission is to increase professional efficiency by having a centralized place where users can solve their problems using AI.
