Simulation Engineer

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards. As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously. We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.

The role involves building and maintaining the modelling and simulation environments that let us understand how our platforms will actually behave, aerodynamically, structurally, and as part of a full engagement, before they're built, and help interpret what happens after they fly. You'll work closely with GNC, mechanical, and systems engineers, and you'll be expected to hold your models to the same standard we hold our hardware: are they good enough to trust a decision on, and how do you know.

Day-to-day responsibilities include:

• Building and maintaining high-fidelity simulation environments, 6-DOF vehicle dynamics, aerodynamics, structural, and/or engagement-level models.
• Developing Monte Carlo and sensitivity analysis capability to explore performance across the real range of conditions a platform will see.
• Working with GNC, mechanical, and systems engineers to define what needs modelling, at what fidelity, and why.
• Validating models against real test and flight data, ensuring model credibility.
• Supporting design trade studies across various parameters using simulation.
• Building tooling and infrastructure that makes simulation faster and more accessible across engineering teams.
• Supporting flight and ground test campaigns, defining what to instrument and measure.
• Communicating simulation results and their limitations clearly to engineers and decision-makers.

You should apply if you:

• Have built and maintained simulation environments for a real physical system in aerospace, automotive, robotics, or a similarly dynamic and safety-relevant domain.
• Understand the underlying physics well enough to know when a model is a reasonable simplification.
• Are strong in a relevant programming/scientific computing environment (Python, MATLAB/Simulink, C++, or equivalent).
• Have experience validating simulation output against real test or field data.
• Are comfortable working with uncertainty, Monte Carlo methods, and sensitivity analysis.
• Can collaborate effectively across disciplines and explain simulation results clearly.

Nice to Have:

• Experience with 6-DOF flight/missile simulation or engagement-level/wargaming simulation.
• Experience with CFD, FEA, or other high-fidelity physics-based modelling tools.
• Familiarity with real-time or hardware-in-the-loop (HITL) simulation environments.
• Experience building simulation tooling or infrastructure used by a wider engineering team.
• Exposure to flight test or range test data analysis and model correlation.

Join Helsing and work with world-leading experts in their fields. Our work is important. You’ll be directly contributing to the protection of democratic countries while balancing both ethical and geopolitical concerns. The work is unique, operating in a domain with highly unusual technical requirements and constraints, where robustness, safety, and ethical considerations are vital.

What we offer includes competitive salary and VSOP options, relocation support, learning allowances, health & wellness benefits, social events, enhanced parental leave, family support, and a hands-on onboarding program.

Helsing is an equal opportunities employer. We are committed to equal employment opportunity regardless of race, religion, sexual orientation, age, marital status, disability or gender identity.
