Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following a $200M Series B at $1.4B valuation, the company is expanding engineering teams to deliver mission-critical systems to allied forces.
You will join the engineering team in Lausanne as a hands-on Senior Mechanical Engineer, taking end-to-end ownership of mechanical design, numerical simulation, and physical validation of specialized mechanical and electromechanical structures. Your work will optimize system performance and match hardware capabilities to demanding operational requirements.
Key responsibilities:
• Structural & Dynamics Simulation: Run non-linear explicit finite element simulations to build predictive models for structural integrity, dynamic impact, vibration response, and high-velocity mechanical behavior in extreme operational environments.
• CAD Design & Drafting: Create and maintain complex CAD models, structural housings, mechanisms, and technical drawings for production release.
• Empirical Testing & Data Capture: Write R&D test specifications for environmental, drop, structural, and shock testing. Source specialized testing equipment, manage range and lab setups, and analyze sensor data to validate simulation accuracy.
• Cross-Functional Integration: Work directly with multidisciplinary engineering teams to advise on physical constraints, payload optimization, spatial layouts, and mechanical integration parameters.
• Safety & Hazard Assessments: Conduct system-level hazard analyses and safety evaluations for critical mechanical mechanisms and energetic system interfaces.
• Production & Field Support: Document hardware performance guidelines, assist with first-production validation, optimize designs for manufacturing processes, and provide technical support during end-user demos and customer engagements.
You will see designs through from concept to production and final delivery, with regular opportunities to test and validate hardware in realistic operational environments.
REQUIREMENTS:
• Education: B.Sc. or M.Sc. in Mechanical Engineering, Aerospace Engineering, Applied Physics, or related technical discipline.
• Simulation Expertise: Hands-on experience with non-linear explicit finite element analysis applied to high-velocity mechanical impact, dynamic loading, shock waves, and material failure models.
• Mechanical Systems Knowledge: Deep understanding of mechanical hardware, structural mechanics, tolerance stack-ups, thermal dissipation, and dynamic load transfer.
• R&D Range & Lab Testing: Practical experience setting up, executing, and analyzing data from physical prototype testing, environmental chambers, dynamic test tracks, or field evaluation programs.
• CAD & Manufacturing: Solid proficiency in standard CAD software for complex assembly design, mechanical drafting, and manufacturing processes (CNC machining, additive manufacturing, injection molding).
• Drive & Ownership: Practical problem-solver who takes full responsibility for hardware deliverables and balances physical analysis with project timelines.
