About the Job About Starflight Dynamics Starflight Dynamics (SFDY) is a Munich-based SpaceTech company building the foundational technologies for Europe's next generation of orbital infrastructure.

If that's you — but you're genuinely excited about building the foundations of Europe's orbital infrastructure — we'd strongly encourage you to apply anyway. We care more about drive and capability than a perfect match on paper. We believe diversity of background and perspective drives better engineering and better decisions, and we welcome applications regardless of gender, age, nationality, disability, religion, or sexual orientation.
