Company

hirify.global develops autonomous and scalable defense systems for allied forces.

What you will do

• Own the mechanical architecture of lightweight quadcopter platforms from CAD concept through production release.
• Design fuselages, chassis, motor mounts, quick-release mechanisms, and other airframe assemblies in SolidWorks.
• Package PCBs, wire harnesses, power distribution, motors, and sensors into custom airframe volumes.
• Build functional prototypes and perform vibration, modal, thermal, drop, and flight-test validation.
• Run structural, modal, thermal, and tolerance stack-up analyses for demanding defense environments.
• Optimize parts for injection molding, CNC machining, sheet metal, and additive manufacturing, while supporting assembly processes and production tooling.

Requirements

• M.Sc. or B.Sc. in Mechanical Engineering or a related technical field.
• 4+ years of hands-on UAV design and development experience with physical drone airframes, multirotors, or flight hardware, or 6+ years of mechanical engineering experience in robotics, autonomous systems, or dense electromechanical hardware.
• Experience taking electromechanical assemblies from CAD concepts through prototypes to production hardware.
• Practical design-for-manufacturing experience with plastic injection molding, CNC machining, sheet metal, and 3D printing.
• Ability to solve structural rigidity, heat dissipation, vibration isolation, and other real-world physical constraints.
• Proactive, hands-on, collaborative approach with strong ownership under tight deadlines.

Culture & Benefits

• Work on autonomous defense systems with real-world mission impact.
• Operate in a demanding R&D environment focused on rigor, ownership, execution, and ambitious technical goals.
• Collaborate with cross-functional engineering, industrialization, procurement, suppliers, and production teams.
• Work directly with physical hardware from initial design through validation and manufacturing.
