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.

Your Role:

As a Payload System Engineer, you’ll be part of the Mission and Space Systems team. You’ll collaborate daily with the other engineers of the team as well as the operations teams and external partners. Your role will be instrumental in both supporting the performance of our orbiting satellites by developing deep technical knowledge of our current payload, and shaping the future of our constellation by contributing to the design and development of our next-generation payload.

Key Responsibilities:

• Derivation of technical payload requirements from top-level specifications.
• Perform design trade-offs targeting the most efficient solutions with respect to technological and programmatic constraints.
• Co-design and co-development of the payload together with partners.
• Support, implementation, and management of supplier reviews.
• Write and maintain requirement specifications, coordinating with procurement and AIT teams to ensure supplier performance.
• Define and maintain payload budgets (radiometry, image quality, data rate, etc.).
• Perform payload functional and performance analysis and testing.
• Support operational concept definition, mission analysis, and system-level performance assessments with payload-related inputs.
• Support the completion of all necessary payload documentation for the qualification and certification of flight systems, as well as associated verification requirements and test result evaluations.
• Collaborate with the other teams to define necessary requirements and interfaces.
• Participate in the payload and satellite-level Assembly, Integration, and Testing (AIT) activities, and support their planning and definition.
• Participate in the development of our internal test and system engineering software.
