Design & Simulation Engineer at Harmattan AI

The role

Harmattan AI is seeking a Senior Mechanical Engineer in Lausanne to lead the end-to-end design and validation of specialized defense structures. You will manage mechanical architectures from initial CAD modeling and non-linear simulations through to physical testing and production delivery.

What you'll do

• Run non-linear explicit finite element simulations for structural integrity and dynamic impact
• Create complex CAD models and technical drawings for production release
• Write R&D test specifications and manage lab and range testing setups
• Advise multidisciplinary teams on physical constraints and mechanical integration
• Conduct system-level hazard analyses and safety evaluations for mechanical mechanisms
• Support first-production validation and provide technical assistance during customer demos

What you'll bring

• Degree in Mechanical Engineering, Aerospace Engineering, or Applied Physics
• Experience with non-linear explicit finite element analysis and material failure models
• Deep understanding of structural mechanics, tolerance stack-ups, and dynamic load transfer
• Practical experience executing physical prototype testing in lab or field environments
• Proficiency in CAD software and knowledge of various manufacturing processes

Your impact

You will play a critical role in delivering high-performance autonomous defense systems to allied forces by ensuring structural reliability under extreme conditions. Your work directly bridges the gap between predictive simulation and real-world hardware performance in mission-critical environments.
