Systems Software Engineer

Real-Time Systems Software Engineer

Based in Stevenage | Salary up to £65k

Some software engineering roles are comfortable. Familiar stack, predictable problems, another sprint planning meeting. This isn't one of those.

You’ll be writing C++ on Linux, working with high‑speed SFPDP data pipelines and multi‑threaded architectures that feed directly into the validation of some of the most advanced defence systems in the world. Real hardware. Real consequences. The kind of work that actually matters.

The team is small and experienced. No passengers. You’ll own problems, make decisions, and see the results of your work in systems that get used.

You need solid C++ and Linux skills; genuine experience with real‑time data systems and concurrent programming; and the instinct to go deep when something isn’t working. SFPDP experience is a bonus, not a deal breaker.

You must be eligible for UK Security Clearance and comfortable being based full‑time on‑site in Stevenage.

Up to £2,500 bonus, 14% pension, flexi leave, and paid overtime.

If you’ve been building real‑time systems and you want the work to mean something, this is worth a conversation.
