Flight Software Engineer

Flight Software Engineer – LEO & GEO Spacecraft

Join a pioneering team at the forefront of satellite innovation, designing and deploying cutting-edge spacecraft for both Low Earth Orbit (LEO) and Geostationary Orbit (GEO) applications. This company is on a mission to reshape on-orbit capability through robust software and mission-driven engineering. As a Flight Software Engineer, you’ll play a key role in building, testing, and deploying flight-critical code for complex spacecraft systems.

Location: Hybrid -London

Type: Permanent (Contract options may be considered – ask us!)

What You’ll Be Working On:

• Developing, testing, and integrating embedded flight software in C, C++, and Python
• Working across the full flight software stack: hardware interfaces, middleware, command & data handling, FDIR, autonomy, and comms
• Supporting both development and on-orbit operations for GEO and LEO missions
• Collaborating with multidisciplinary teams including GNC, Systems, and Mission Ops
• Driving software robustness, system reliability, and mission success

What They’re Looking For:

• 3+ years of experience in flight or embedded software development (space or aerospace preferred)
• Strong skills in C/C++ and Python in real-time and/or safety-critical environments
• Familiarity with spacecraft avionics, RTOS, and telemetry/command systems
• Proficiency in version control tools (Git, GitLab, or similar)
• Experience with integration and test campaigns for space vehicles
• Strong problem-solving mindset and team-first attitude

Bonus Points:

• Experience with flight heritage spacecraft
• Familiarity with LEO/GEO mission constraints or communication architectures
• Exposure to software-in-the-loop (SIL) or hardware-in-the-loop (HIL) testing

This is an opportunity to shape flight systems on some of the most exciting missions in orbit. You’ll work in a dynamic environment, surrounded by technical experts who are passionate about space and software excellence.
