We are seeking a Senior Flight Software Engineer to join a high-performing engineering team working on cutting-edge space missions focused on the future sustainability of the space environment.
This role sits within a specialist Flight Software team responsible for developing embedded real-time software for advanced spacecraft systems, including next-generation missions designed to support satellite servicing and orbital debris removal.
This is an excellent opportunity for an experienced embedded software engineer looking to work on innovative, mission‑critical space programmes and play a key role in shaping the future of in‑orbit operations.
You will be responsible for the development of onboard flight software for satellite systems, working closely with multidisciplinary teams across systems, GNC, and computer vision.
The position covers the full software lifecycle, from requirements definition through to integration, verification, and testing.
Key Responsibilities
* Design, develop, and verify onboard flight software for spacecraft systems
* Collaborate with subsystem and system-level teams to define software requirements and solutions
* Contribute to and support design reviews, ensuring software compliance and performance
* Act as a subject matter expert in flight software development
* Support integration of Computer Vision and Guidance, Navigation & Control (GNC) software into the flight environment
* Contribute to knowledge sharing and provide technical input across engineering teams
Essential Requirements
* Degree in Computer Science, Software Engineering, or a relevant technical discipline
* Experience developing flight software for space applications
* Strong knowledge of ECSS standards for flight software
* Proven experience in real-time embedded software development (C/C++)
* Solid understanding of software development methodologies and embedded systems engineering
* Experience designing and implementing real-time systems
* Self‑motivated, proactive, and able to take ownership while working collaboratively within a team
Desirable Skills
* Experience within the space sector or other safety‑critical industries
* Development experience with VxWorks or RTEMS
* Familiarity with the full mission lifecycle (concept through to operations)
* Knowledge of UML and software modelling techniques
* Experience with spacecraft communication protocols (e.g. CCSDS, CAN, SpaceWire)
* Familiarity with cFS (Core Flight System)
* Experience with SPARC V8 or PowerPC architectures
* Linux development and system administration experience
* Scripting experience (e.g. shell, Python)
What's on Offer
* Opportunity to work on cutting‑edge space missions and technologies
* Flexible working arrangements, including hybrid options
* Optional compressed working schedule (e.g. 9/75 pattern)
* 25 days annual leave (increasing with service) + bank holidays
* Private healthcare and life insurance
* Long‑term sick pay support
* Relocation support (where applicable)
