GNC Modelling and Simulation Engineer

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 Flight Dynamics & Control Engineer, 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

• Develop and maintain simulation models (e.g. 6-DOF, aerodynamic, thermal, or subsystem-level) supporting vehicle design and test.

• Support trade studies and performance analysis using simulation tools.

• Validate simulation models against test and flight data.

• Collaborate with avionics, GNC, and systems engineering teams to define simulation requirements.

• Maintain simulation model documentation and version control in line with requirements.

Who you are

• Degree in Aerospace Engineering, Mechanical Engineering, Computer Engineering, Applied Mathematics, or a related field.

• Experience with modelling & simulation tools (MATLAB/Simulink, Python, or similar).

• Understanding of flight dynamics, aerodynamics, or control systems is a plus.

• Strong analytical and software development skills.

• Experience with high-fidelity or Monte Carlo simulation methods is a plus.

What we offer

• A 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.
