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.
As our Software Verification Test Engineer for the GNC team 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 doOwn verification and test activities for Navigation, Guidance, and Control (GNC) algorithms across development stages.Define clear, risk driven verification test plans that map system and algorithm requirements to executable tests.Execute algorithm verification through simulation, MIL, SIL, and HIL environments in close coordination with design and integration teams.Analyse test data to identify failure modes, performance gaps, and edge cases across the flight envelope.Feed verification results back into model and algorithm improvement, closing the loop between test and design.Produce concise, decision focused test reports that enable rapid engineering and programme decisions.Support readiness reviews and contribute evidence toward system qualification and flight confidence.Who you areA verification, test, or systems engineer with 3+ years’ experience working on control, navigation, or guidance software in aerospace or defence.Comfortable thinking in terms of requirements, risks, and evidence, not just test execution.Strong at breaking algorithms, exploring edge cases, and exposing behaviours before flight does.Fluent working with simulation-heavy environments, and confident interpreting complex test data.Someone who naturally closes the loop between test results and model or algorithm improvement.Able to communicate findings through clear, decision-grade reporting rather than raw data dumps.Balanced in mindset: rigorous about correctness, but aligned with programme pace and iteration speed.Motivated by building confidence in flight-critical software where verification quality directly affects mission success.What we offerA 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.At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven. If this role feels like a strong fit, or if you believe you bring something exceptional that goes beyond the description, we encourage you to apply.
Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential.
You can apply directly to this role or reach out to Nathan Sweeney, Head of Talent. We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no.
