[Hiring] Payload Flight Software Engineer @Constellr

Role Description

As part of the constellr Imaging Operations team, you will build, maintain, and operationalize our onboard payload software — carrying the payload from commissioning through to day-to-day in-orbit operations across the satellite's full lifecycle. This is a hands-on, high-impact role focused on turning flight software into reliable, operational reality.

• Involved in the design and contribute operational feedback that helps shape it.
• Drive the operationalization of in-orbit payload software, supporting operations, anomaly solving, and commissioning on each new satellite.
• Collaborate closely across the business — working day-to-day with internal engineering teams, Product Assurance, Project Management, and Operations, as well as external suppliers.
• Operate at a high interface with the hardware and operations teams, ensuring the software runs reliably on the payload hardware.
• Your work will directly influence the reliability, performance, and long-term success of constellr's mission.

Qualifications

• Degree in Aerospace Engineering, Software Engineering, Computer Science, or a related field.

• Experience with scripting languages such as Bash and Lua (Nice to Have).
• Experience with Java, C, or C++ (Nice to Have).

Benefits

• High-Impact National Security Mission: Be part of an ambitious mission to launch the world’s first commercial thermal infrared constellation.
• Fast-Paced "New Space" Innovation: Work at the leading edge of a rapidly evolving defence sector.
• Broad Interdisciplinary Exposure: Collaborate daily with a diverse, international cohort of astrophysicists, software developers, and defence-system engineers.
