Design & Simulation Engineer
About this role
About Us Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges.
We operate in a demanding environment where rigor, ownership, and execution are expected. The Role We are looking for a hands-on Senior Mechanical Engineer to join our engineering team in Lausanne. You will handle the end-to-end design, numerical simulation, and physical validation of specialised mechanical and electromechanical structures to optimize system performance and match hardware capabilities to demanding operational requirements.
From day one, you will take ownership of mechanical architectures and physical assemblies. You will run non-linear explicit finite element simulations, build high-precision CAD models, set up lab and range tests, and see designs through to production and final delivery. What You Will Do 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 against extreme physical 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. What We Are Looking For Background: B.Sc .
