Senior Mechanical Engineer – Quadcopter Systems

ph3bAbout Us /b /h3pHarmattan 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. /ppOur 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. /ppWe are seeking a high-drive, hands-on Senior Mechanical Engineer to join our dedicated Quadcopter Airframe team in Lausanne. In this role, you will own the end-to-end mechanical architecture of our flagship multirotor platforms—from initial CAD concept and structural design to payload packaging, physical prototyping, and production release. /ppFrom day one, you will take full ownership of real hardware: designing complex assemblies in SolidWorks, solving heat and vibration challenges, running lab validation, and driving parts through production alongside our cross-functional engineering teams. /ph3bWhat You Will Do /b /h3ullipbQuadcopter Subsystem Architecture: /b Lead the mechanical design and modeling of lightweight quadcopter structures, fuselages, chassis, motor mounts, and quick-release mechanisms in SolidWorks from concept to production. /p /lilipbElectromechanical Packaging: /b Lead spatial layouts and enclosure design to integrate electrical components (PCBs, wire harnesses, power distribution, motors, and sensors) tightly into custom airframe volumes. /p /lilipbRapid Prototyping Physical Testing: /b Build functional prototypes and execute hands-on lab validation—including vibrational testing, modal analysis, thermal chamber runs, drop testing, and assisting with flight tests. /p /lilipbSimulation Thermal Analysis: /b Perform structural (FEA), modal, and thermal simulations alongside tolerance stack-up analyses to ensure designs withstand extreme defense operational environments. /p /lilipbDFM Production Documentation: /b Partner with Industrialisation, Procurement, and suppliers to optimise parts for plastic injection molding, CNC machining, sheet metal, and additive manufacturing. /p /lilipbAssembly Enablement: /b Support Industrialisation engineers in defining assembly sequences, designing build jigs and fixtures, and training production operators to ensure high build quality and fast throughput. /p /li /ulh3bWhat We Are Looking For /b /h3ullipbBackground: /b M.Sc. or B.Sc. (FH / HES / University of Applied Sciences) in Mechanical Engineering or a related technical field. /p /lilipbExperience: /b /pullipb4+ years /b of hardcore, hands-on UAV design and development experience (demonstrated track record with physical drone airframes, multirotors, or flight hardware), OR /p /lilipb6+ years /b of overall mechanical engineering experience in complex Robotics, Autonomous Systems, or high-density Electromechanical hardware. /p /li /ul /lilipbEnd-to-End Ownership: /b Proven track record taking complex electromechanical assemblies from CAD concepts through functional prototypes to finished, physical production hardware. /p /lilipbDFM Grounding: /b Practical design experience for plastic injection molding, CNC machining, sheet metal, and 3D printing, with direct supplier collaboration experience. /p /lilipbApplied Physics Problem Solving: /b Demonstrated skill in managing real-world physical constraints—including structural rigidity, heat dissipation, and vibration isolation. /p /lilipbHigh Ownership Drive: /b Proactive, responsive, and collaborative mindset—someone who takes full responsibility for their work and actively unblocks themselves under tight deadlines. /p /li /ulh3bWhat We Offer /b /h3ullipbComplete System Ownership: /b Own the complete mechanical architecture of flagship quadcopter platforms rather than being siloed on a single bracket or cover. /p /lilipbUnmatched Execution Speed: /b Move from CAD design to physical shop-floor testing in days, backed by strong resources and quick decision-making. /p /lilipbDirect Mission Impact: /b Design and build hardware that actively deploys with allied forces to solve critical defense challenges. /p /lilipbCross-Functional Mastery: /b Work side-by-side with Electrical, Aerodynamics, Gimbal, and Production teams with complete visibility over how hardware moves from CAD to active flight. /p /li /ulpWe look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI. /p /p #J-18808-Ljbffr
