Avionics System Engineer

About this role

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, build, and test avionics subsystems (power distribution, data buses, sensor interfaces, flight computer integration) to meet requirements set by the avionics architecture lead. Support development and upkeep of avionics requirements, interface control documents (ICDs), and verification & validation (V&V) test plans.

Execute avionics AIT (assembly, integration & test) activities: write and run test procedures, capture data, and support anomaly investigation and root-cause analysis. Support supplier and vendor coordination for avionics components (flight computers, sensors, actuators, harnessing) — including incoming inspection, qualification testing, and non-conformance tracking. Contribute to flight readiness reviews and perform post-test/post-flight data analysis and reporting.

Maintain avionics design and test documentation in line with applicable export control classifications and configuration management practices. Collaborate day-to-day with GNC, propulsion, and structures engineers to resolve interface and integration issues. Who You Are Degree in Electrical/Electronic/Aerospace Engineering, or equivalent demonstrable experience. Hands-on experience with avionics system design or integration on complex vehicles (aerospace, defence, automotive, or comparable high-reliability domain) Working knowledge of avionics architectures: power distribution, data buses (e.g.
