Payload Flight Software Engineer

Role overview Join an Earth observation imaging operations team to build and run the onboard software that powers a commercial thermal infrared satellite constellation. This is a hands-on role focused on taking flight software from design through commissioning and routine in-orbit operations, working closely with hardware, product assurance, and mission operations colleagues.

Responsibilities - Develop, test, and maintain high-reliability onboard payload software that meets aerospace product assurance and safety standards - Support payload commissioning and on-orbit activities for each new satellite in the constellation - Provide operational feedback into software requirements and design, collaborating across engineering, product assurance, and operations - Implement and validate Fault Detection, Isolation, and Recovery (FDIR) strategies to improve onboard autonomy and resilience - Carry out integration and verification work using flat-sat benches and other ground-based simulation platforms - Investigate and resolve payload anomalies, and help shape the in-orbit software update process

Requirements - Degree in Aerospace Engineering, Software Engineering, Computer Science, or a related field - At least four years of experience in software development or software assurance, preferably in aerospace or another safety-critical domain - Solid embedded software development experience and grounding in modern software engineering practices - Hands-on experience with Git, CI/CD pipelines, and software testing frameworks - Proficiency in Python and familiarity with common communication protocols such as CCSDS or CSP

Nice to have - Experience with satellite commanding systems and procedures - Familiarity with onboard and ground-based FDIR workflows - Scripting in Bash or Lua, and exposure to Java, C, or C++

Benefits and work setup - Opportunity to contribute to a sovereign-grade thermal intelligence programme serving defence and government customers - Hybrid working model with a flat, interdisciplinary engineering culture - Virtual share option plan for permanent employees - Collaboration with physicists, software developers, and systems engineers across the organisation
