Senior Software Engineer, Systems Integration

Help Build Europe's Hypersonic Capability At Hypersonica , we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast.

By joining Hypersonica , you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company.

Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously. We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual.

If you’ve achieved what others said was impossible, or you bring a unique combination of skills that doesn’t fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe’s technological independence.

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
