Embedded Flight Software Engineer

Our Mission At constellr, we're harnessing the power of space to solve one of Earth’s greatest challenges: climate resilience & security in a changing world. Our thermal satellite constellation delivers the most accurate land surface temperature data on the market, equipping commercial players, governments, defence agencies, and global institutions with the thermal intelligence they need to make strategic decisions– from national security and infrastructure to agriculture and climate resilience. As a fast-scaling company with offices in Brussels, Freiburg, Munich, Washington and Toulouse, our multidisciplinary team of engineers, scientists, and strategists is building the future of space-based Earth observation Location: Remote or Hybrid - Germany Team & Reporting Line: Mission and Space Segment - Reporting to Lead Satellite Systems Your Role You will join the constellr Mission & Space Segment team , playing a key role in shaping the onboard software that powers our satellite constellation across its full lifecycle — from early design through to in-orbit operations. This is a hands-on, high-impact role where you will help define how our satellites compute, behave, and evolve in space. Your work will directly influence the reliability, performance, and long-term success of constellr’s mission. You’ll collaborate closely across the business — working day-to-day with internal engineering teams, Product Assurance, Project Management, and Operations , as well as external suppliers. Together, you will help turn mission concepts into robust, flight-ready software systems. In addition to software development, you will contribute to system-level design decisions, support procurement and supplier technical alignment, and help ensure our onboard software is continuously validated, improved, and ready for operation in orbit.
