About the role

Senior Mechanical Engineer responsible for end-to-end mechanical architecture of Harmattan AI's quadcopter platforms, from concept and CAD design to production release, with hands-on hardware ownership in Lausanne.

Responsibilities

  • Quadcopter & Subsystem Architecture: Lead mechanical design and modeling of lightweight quadcopter structures, fuselages, chassis, motor mounts, and quick-release mechanisms in SolidWorks from concept to production.
  • Electromechanical Packaging: Lead spatial layouts and enclosure design to integrate electrical components (PCBs, wire harnesses, power distribution, motors, and sensors) into custom airframe volumes.
  • Rapid Prototyping & Physical Testing: Build functional prototypes and perform lab validation including vibrational testing, modal analysis, thermal chamber runs, drop testing, and assist with flight tests.
  • Simulation & Thermal Analysis: Perform structural (FEA), modal, and thermal simulations and tolerance stack-up analyses to withstand extreme defense environments.
  • DFM & Production Documentation: Collaborate with Industrialisation, Procurement, and suppliers to optimise parts for plastic injection molding, CNC machining, sheet metal, and additive manufacturing.
  • Assembly Enablement: Support assembly sequences, design build jigs/fixtures, and train production operators for high build quality and throughput.

Qualifications

  • M.Sc or B.Sc (FH / HES / University of Applied Sciences) in Mechanical Engineering or related field.
  • 4+ years of hands-on UAV design and development experience (or 6+ years in mechanical engineering for Robotics/Autonomous Systems/hi-density electromechanical hardware).
  • End-to-End Ownership: Proven ability to take assemblies from CAD concepts to functional prototypes to production hardware.
  • DFM Grounding: Experience with plastic injection molding, CNC machining, sheet metal, 3D printing, and direct supplier collaboration.
  • Applied Physics & Problem Solving: Demonstrated ability to manage constraints like rigidity, heat dissipation, and vibration isolation.
  • High Ownership & Drive: Proactive, collaborative, capable of meeting tight deadlines.
