Mechanical Engineer - World Record Drone Project

About the role

OneSec is developing small AI-powered delivery drones and has built an experimental drone aiming to beat the world record for longest drone flight (currently 5 hours 10 minutes). The Mechanical Engineer takes ownership of key parts of the aircraft's mechanical design, including airframe, propulsion integration, battery structure, lightweight components and manufacturing approach. The role is highly practical, covering CAD design, 3D printing, workshop assembly, testing and rapid iteration, with the chance to take part in an official world-record attempt.

Key responsibilities

• Design and optimise the drone's mechanical structure in SolidWorks
• Reduce aircraft weight while keeping sufficient strength and stiffness
• Design mounts, enclosures, battery structures, landing components and propulsion-system interfaces
• Produce parts by 3D printing, CNC machining, composites and other rapid-prototyping methods
• Assemble, modify and repair physical prototypes in the workshop
• Run structural, vibration, endurance and flight-related tests
• Analyse failures and redesign components quickly based on test results
• Work with electrical, propulsion and flight-control engineers
• Help prepare the aircraft for an official world-record flight attempt

Required profile

• Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics or a related technical field
• Experience designing parts that have been manufactured and assembled
• Familiarity with 3D printing and rapid prototyping
• Comfortable using workshop tools such as drills, Dremels, saws, adhesives and hand tools
• Understanding of mechanical design, materials, fasteners, tolerances and structural loads
• Experience with lightweight structures, composites, drones, aircraft or robotics is a plus
• Strong problem-solving skills and a practical, hands-on approach

Required skills

• SolidWorks or equivalent CAD
• 3D printing and rapid prototyping
• Workshop tools and mechanical design

What we offer

• The chance to break a world record
• A talented team working on cutting-edge drone and AI technology
• Good compensation and equity participation (stock options)
