We protect critical infrastructure. We protect Europe’s sovereignty. We are looking for a new team member who is eager to make a real difference! As a Senior Full-Stack Developer, you will be responsible for designing and developing scalable military ground control station applications coordinating various effectors and integrating with external systems in real-time mission-critical environments . Your roadmap to make an impact Own the backend and integration layer for ground systems the services connecting operator tools, vehicles, sensors, and mission infrastructure Design event-driven architectures and durable interface contracts so frontend, embedded, and partner systems can integrate and evolve safely Build software that holds up in real operations, from telemetry pipelines to deployment, and follow problems across service boundaries end to end (including occasional lab or field support) Raise engineering standards through design, code review, and mentoring, working closely with frontend, embedded, and guidance/navigation/control engineers We care more about strong software engineers than checkbox perfection. If you meet most of these and are motivated to grow into the rest, please still apply tell us where you are strong and where you would ramp up.
