Job summary

OneSec is seeking a hands-on R&D Mechanical Engineer to design and build a variable-angle wind tunnel for testing VTOL delivery drones. The wind tunnel will generate controlled wind speeds and directions while the aircraft remains mounted on a force‑measurement test stand.

This is a highly practical role involving CAD design, prototyping, fabrication, assembly, instrumentation, testing, and continuous improvement.

Qualifications

• Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or related field.
• Experience designing and building mechanical systems or test equipment.
• Strong CAD skills with SolidWorks or equivalent.

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 with flight-control and embedded-software engineers to integrate the wind tunnel into verification pipeline.
• Improve the system based on test results and data.

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)
