Mechanical Engineer — World Record Drone Project

About OneSec

OneSec is making food delivery 3 times faster and 10 times cheaper, by developing small AI powered delivery drones. Visit our website for more info: www.OneSec.com

Role Overview

OneSec has developed an experimental drone that can beat the world record for longest ever drone flight. Achieving 5 hours 10 minutes of flight time, compared to the previous records of 3-4 hours. Your job will be to implement additional improvements, that are estimated to increase the record further, to almost 6 hours.

You will take ownership of key parts of the aircraft’s mechanical design, including its airframe, propulsion integration, battery structure, lightweight components, and manufacturing approach. This is a highly practical role involving CAD design, 3D printing, workshop assembly, testing, and rapid iteration.

The successful candidate will have the opportunity to participate directly in an official world-record.

Key Responsibilities

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

Qualifications

• Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or a related technical field
• Strong SolidWorks or equivalent CAD skills
• Experience designing parts that have been physically manufactured and assembled
• Familiarity with 3D printing and rapid prototyping
• Comfortable using workshop tools such as drills, Dremels, saws, adhesives, and hand tools
• Good 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
