The role emphasizes building reliable interfaces, validating software against hardware, and delivering robust diagnostics and secure software-update paths.

Qualifications

• 5+ years of experience integrating software with hardware in regulated environments.
• Strong knowledge of modern C++ and Rust; Python for testing and tooling.
• Experience with hardware interfaces and protocols: Ethernet (UDP/TCP), serial, and fieldbuses.
• Experience in aerospace/defence or other regulated fields is desirable.

Responsibilities

• Design and build reliable, deterministic interfaces and drivers from ICDs to testing with HITL simulators.
• Own the validation logic between planning software and hardware.
• Build diagnostics and secure software-update paths for deployed equipment.
• Build SITL emulators for the hardware you integrate to support the CI/test environment.
• Lead the software side of qualification with verification plans and traceability from requirement to test.
• Own the software assurance pipeline in CI/CD: reproducible builds, secure boot, SBOMs and static analysis.
• Utilize AI coding agents as tools for drafting tests, interface code, and emulators, with human review.

Job Description

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 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
