About the role

Senior hands-on Mechanical Engineer role focused on end-to-end design, numerical simulation, and physical validation of mechanical and electromechanical structures to optimize system performance and meet demanding operational requirements in autonomous defense systems.

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 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.

Qualifications

  • B.Sc. or M.Sc. in Mechanical Engineering, Aerospace Engineering, Applied Physics, or related technical discipline.
  • Hands-on experience with non-linear explicit finite element analysis for high-velocity mechanical impact, dynamic loading, shock waves, and material failure models.
  • Deep understanding of mechanical hardware, structural mechanics, tolerance stack-ups, thermal dissipation, and dynamic load transfer.
  • Practical experience setting up, executing, and analyzing data from physical prototype testing, environmental chambers, dynamic test tracks, or field evaluation programs.
  • Proficiency in standard CAD software for complex assembly design, mechanical drafting, and manufacturing processes like CNC machining, additive manufacturing, or injection molding.
  • Demonstrated drive and ownership for hardware deliverables and ability to balance physical analysis with project timelines.
