Embedded Flight Software Engineer

Role overview Contribute to the onboard flight software that runs a commercial thermal-infrared Earth-observation satellite constellation. Working within a mission and space-segment team, you will design, develop, and validate high-reliability embedded software from early concept through in-orbit operations, collaborating closely with systems engineering, product assurance, and external suppliers.

Responsibilities - Design, develop, test, and maintain high-reliability onboard flight software that complies with product assurance and safety standards. - Shape onboard software architecture supporting both laboratory validation environments and in-orbit operational systems. - Define and implement Fault Detection, Isolation and Recovery (FDIR) strategies for satellite autonomy and resilience. - Coordinate delivery of new software features and upgrades with external suppliers and development partners. - Drive verification and validation strategy and participate in end-to-end V&V campaigns, including Flatsat-based integration testing. - Champion configuration management, traceability, and integrity across all onboard software components. - Investigate and resolve software anomalies, and help define in-orbit software update processes for the constellation fleet.

Requirements - Degree in Aerospace Engineering, Software Engineering, Computer Science, or a related field. - At least four years of experience developing or assuring software in aerospace or another safety-critical domain. - Embedded software experience including low-level hardware interfaces such as CAN or Camera Link. - Familiarity with FPGA-based systems and ECSS standards, particularly Q-ST-60-02. - Strong software engineering methodology, testing frameworks, and lifecycle management practices. - Proficiency in Python and C++, plus practical Git and CI/CD pipeline experience.

Nice to have - Working knowledge of additional ECSS standards (Q-ST-80C, E-ST-40C, E-ST-70-41C, and related handbooks). - Experience with space communication protocols such as CCSDS and CSP. - Strong analytical, structured problem-solving ability and attention to quality.

Benefits and work setup - Flexible hybrid working, a Virtual Share Option Plan for permanent employees, and an inclusive, science-driven culture with interdisciplinary collaboration across astrophysics, software, and defence-systems engineering.
