Simulation Engineer at Hypersonica

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

Build the Simulation Environment: Develop and manage the end-to-end architecture for effectiveness modelling, ensuring the environment can simulate complex interactions.
Conduct Trade-Off Studies. Perform sensitivity and trade-off analyses to balance variables like mass, shape, and material choices against mission requirements.

Improve the Models: Establish the methodology for validating simulation results against physical test data, ensuring the digital environment accurately reflects real-world physics.

Inform Design Decisions: Provide data-driven insights to the broader engineering team to determine key dependencies and constraints and to optimize overall system effectiveness

Standardize Metrics. Define and track quantitative performance indicators to measure system success.

Who you are

You have 3+ years of experience in simulation and modelling. Background in weapons effects modelling is preferred.

You have a strong background in numerical simulation in either of high-speed flows using CFD, explicit dynamics using FEM, or Lagrangian particle tracking for modelling explosive events.

You have the technical skill to build automated workflows and simulation pipelines rather than just running existing tools.

You are comfortable in ambiguous, fast-paced environments. You don’t wait for a perfect roadmap; you create the path forward, bringing cross-functional colleagues along and ensuring the team maintains momentum in a collaborative way.

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.

Security and Eligibility Requirement

Due to the nature of the work with the German Government, applicants must be a German citizen, and eligible for German Security Clearance and, where required, Developed Vetting.

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.
