About the Role
As Lethality Engineer in R&D, you own the design, numerical simulation and physical validation of specialized mechanical and electromechanical structures. You turn demanding operational requirements into hardware that performs, from early concept through production and delivery. You work hands-on from day one, owning mechanical architectures and physical assemblies end to end.
Responsibilities
Run non-linear explicit finite element simulations to predict structural, impact and vibration behavior in extreme environments.
Design and maintain CAD models of housings, mechanisms and assemblies, and release technical drawings for production.
Write R&D test specifications for environmental, drop, structural and shock testing.
Set up and run lab and range tests, then analyze sensor data to validate simulation accuracy.
Advise multidisciplinary engineering teams on physical constraints, spatial layout and mechanical integration.
Conduct system-level hazard and safety assessments on critical mechanical mechanisms and interfaces.
Document hardware performance guidelines, support first-production validation and optimize designs for manufacturing.
Provide technical support during end-user demos and customer engagements.
Requirements
Candidate Requirements
B.Sc. or M.Sc. in Mechanical Engineering, Aerospace Engineering, Applied Physics or a related technical discipline.
Hands-on experience with non-linear explicit finite element analysis for dynamic loading, impact and material failure.
Solid understanding of structural mechanics, tolerance stack-ups, thermal dissipation and dynamic load transfer.
Practical experience setting up, running and analyzing physical prototype tests, in the lab or in the field.
Proficiency in CAD for complex assemblies and drafting, with knowledge of CNC machining, additive manufacturing or injection molding.
Ownership mindset: you take full responsibility for hardware deliverables and balance analysis rigor with project timelines.
