Simulation Engineer

Hypersonica GmbH; München; On-site; EUR 70,000 - 110,000; Full time

Job summary

Hypersonica GmbH in Munich is seeking a Simulation and Modelling Engineer to build the end-to-end architecture for effectiveness modelling and to run sensitivity and trade-off analyses.

You will validate models against physical test data, drive design decisions with data-driven insights to the broader engineering team, and help create automated simulation pipelines.

Join a small, autonomous team that emphasizes clarity, accountability, and rapid iteration on Europe’s defence technology.

Qualifications

• 3+ years of experience in simulation and modelling, background in weapons effects modelling preferred.
• Strong background in numerical simulation: CFD for high-speed flows, explicit dynamics using FEM, or Lagrangian particle tracking for modelling explosive events.
• Ability to build automated workflows and simulation pipelines, not just run existing tools.
• Comfortable in ambiguous, fast-paced environments; you create the path forward, guiding cross-functional colleagues.

Responsibilities

• Build the end-to-end simulation environment for effectiveness modelling.
• Conduct sensitivity and trade-off analyses balancing variables against mission requirements.
• Improve the models by validating simulation results against physical test data.
• Inform design decisions with data-driven insights to engineering teams.
• Define and track quantitative performance indicators to measure system effectiveness.

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

• 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.

Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential.
