Mechanical Engineer — World Record Drone Project

OneSec; Fatih; On-site; TRY 240,000 - 360,000; Full time

Job summary

OneSec is seeking a hands-on Mechanical Engineer to own the drone's mechanical design. You will design airframe, propulsion interfaces, battery structures, and lightweight components, using SolidWorks and rapid prototyping methods.

The role emphasizes CAD expertise, in-workshop assembly, testing, and iteration, with opportunities to contribute to world-record attempts and collaborate with cross-functional engineers in a fast-paced hardware startup.

Qualifications

• Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or related 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, drones, aircraft, or robotics is a plus.
• Strong problem-solving skills and a practical, hands-on approach.

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

Job description

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.
