Junior Mechanical Engineer – Quadcopter Systems

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. We are seeking a high-drive, hands-on Mechanical Engineer to join our dedicated Quadcopter Airframe team in Lausanne. In this role, you will be on the front lines of designing, prototyping, and integrating next-generation multirotor hardware deployed in mission-critical environments.

From day one, you’ll work directly on physical hardware—modeling custom parts in SolidWorks, building hands-on prototypes, and helping validate them for flight testing. What You Will Do Component CAD Modeling: Design and update production-ready 3D models and assemblies (motor mounts, structural brackets, battery latches, internal mounting plates) in SolidWorks under tight deadlines.

Electromechanical Packaging: Fit electrical components, PCBs, sensors, actuators, and wire harnesses into compact quadcopter airframes without compromising serviceability or thermal routing. Rapid Prototyping & Bench Testing: Operate 3D printers, shop tools, and bench-test setups to physically validate and stress-test your designs before they hit the field.

DFM & Production Documentation: Create precise 2D manufacturing drawings, define tolerances, and generate BOMs for injection molding, CNC machining, 3D printing, and sheet metal fabrication. Cross-Functional Execution: Collaborate closely with Electrical Engineering, Aerodynamics, Industrialisation, and Supply Chain to solve spatial packaging bottlenecks and keep hardware builds moving fast. What We Are Looking For Background: M. Sc . or B.

Sc . (FH / HES / University of Applied Sciences) in Mechanical Engineering, Mechatronics, Aerospace or similar. Experience: 0–3 years of hands-on experience in mechanical engineering, robotics, or electromechanical hardware. Top performance in competitive university hardware teams ( Formula Student / FSAE , robotics clubs, or UAV projects) counts directly toward experience. CAD Fluency: Fast, clean modeling skills in SolidWorks and a solid grasp of para
