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:
We’re looking for a hands-on R&D Mechanical Engineer to design and build a variable-angle wind tunnel for testing our VTOL delivery drones.
The wind tunnel will generate controlled wind speeds and directions while the aircraft remains mounted on a force-measurement test stand. The complete system will include motors, propellers, structural frames, airflow components, force sensors, actuators, and a large pivoting mechanism that allows the wind angle to be adjusted automatically.
This is a highly practical role involving CAD design, prototyping, fabrication, assembly, instrumentation, testing, and continuous improvement.
KEY RESPONSIBILITIES:
Design the complete wind tunnel structure and airflow system
Select and integrate motors, propellers, bearings, actuators, belts, gears, and structural components
Develop a pivoting mechanism that can automatically change the wind tunnel angle
Design test stands and fixtures for mounting VTOL aircraft
Integrate force sensors and other measurement equipment into the test setup
Create parts and assemblies in SolidWorks
Produce components using 3D printing, CNC machining, sheet materials, and workshop fabrication
Assemble, modify, and troubleshoot the physical system
Conduct airflow, vibration, structural, and mechanical tests
Work closely with flight-control and embedded-software engineers to integrate the wind tunnel into our verification pipeline
Improve the system based on test results and experimental data
QUALIFICATIONS:
Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or a related technical field
Strong SolidWorks or equivalent CAD skills
Experience designing and building mechanical systems or test equipment
Familiarity with motors, propellers, bearings, belts, gears, actuators, and structural assemblies
Experience with 3D printing, rapid prototyping, and workshop fabrication
Comfortable using workshop tools such as drills, Dremels, saws, adhesives, and hand tools
Good understanding of mechanical loads, vibration, tolerances, airflow, and structural design
Experience with wind tunnels, test rigs, drones, robotics, or aerospace systems is a plus
Strong problem-solving skills and a practical, hands-on approach
Why You’ll Love Working Here
Design and build a unique variable-angle wind tunnel from the ground up
Work with an exceptionally talented team
Work on cutting edge drone & AI technology
Build real hardware and see it used in aircraft testing
Good compensation
Equity participation (Stock options)
