Senior Fullstack Software Engineer (f/m/d)

What we build Most companies find out about supplier insolvencies, cyber attacks, factory fires or floods that affect their supply chain when it's already a crisis. Prewave exists to change that. We're an AI-native company giving BMW Group, Hilti and Lufthansa real-time visibility into supply chain risks before they become headlines. We're looking for a Senior Fullstack Software Engineer who takes ownership of building and scaling our full-stack platform end-to-end from day one. Someone who uses AI as a default part of how they work - and knows when to trust their own judgment.

For us, AI-native has always meant humans and AI working together, not one replacing the other. We use tools lik e Cursor and Claude as a normal part of the job, to think faster, work smarter and spend less time on the repetitive stuff. We treat AI fluency as a skill like any other - something you build, experiment with and keep developing. What goes with that is real ownership . You'll have the space and the trust to figure things out your way - with a strong team around you and plenty of support when you need it. Things move fast here and the brief won't always be complete, but that's what makes the work interesting. The people who do best at Prewave are curious by default, go after things rather than wait to be handed them, and don't lose their footing when the plan changes.
