What you'll do
Design and build reliable, deterministic interfaces and drivers, from drafting the first interface control document (ICDs), to testing with state-of-the-art HITL simulators.
Own the validation logic between the planning software and the hardware.
Build diagnostics and secure software-update paths for deployed equipment.
Build SITL emulators for the hardware you integrate, so the simulation team and CI can test against them.
Lead the software side of qualification. Write the verification plan, build requirements traceability from requirement to test to result, and make sure every release ships with its test evidence and a controlled configuration.
Own the software assurance pipeline in CI/CD: reproducible builds, secure boot and OS hardening, code signing, software bills of materials (SBOMs) and static analysis.
Use AI coding agents as normal engineering tools: to draft tests, interface code and emulators, to check traceability links, and to prepare evidence. You decide where they are used and how their output is reviewed. Engineers own and sign the evidence.
Who you are
A software engineer with 5+ years' experience integrating software with hardware in aerospace, defence, rail, automotive, medical or another regulated field.
Strong modern C++. Rust is welcome. Python for test automation and tooling.
Hands-on with hardware interfaces and protocols: Ethernet (UDP/TCP), serial, and fieldbuses such as CAN, plus time synchronisation (PTP, GNSS time).
You have taken software through a formal verification or qualification campaign: requirements-based testing, traceability, and configuration and change control.
Comfortable with HITL testing; debugging across the hardware/software boundary.
Able to explain technical risk clearly to systems and safety engineers, and to customers and assessors.
You use AI agents in your own work, and you have clear views on where they help and where they don't.
What we offer
- A mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.
- Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow.
- High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.
- A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions.
- A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.
- Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
