Mechanical Design Engineer [Propulsion]

We are looking for a Mechanical Design Engineer with 3-8 years of experience to own the mechanical design and integration of propulsion components on a hybrid-electric VTOL aircraft that is on the cusp of transitioning from prototype flight testing to customer delivery. You'll join a lean, high-impact propulsion team responsible for the entire powertrain—high-speed generators, motors, inverters, turbines, battery packs, and cooling systems. This is a hands-on role where you'll take real ownership of critical flight hardware, driving designs from concept through build, test, and iteration. The ideal candidate can operate independently, has experience resolving real-world build and test issues, and is excited to shape propulsion systems that will scale into production.

What will you be doing?

Own the mechanical design and integration of propulsion subsystems including motors, high-speed generators, inverters, engine-generator coupling, ducting, and cooling systems

Drive resolution of hardware issues discovered during prototype builds and testing—tolerance stack-ups, fitment issues, and non-conforming parts

Contribute to a new in-house motor design cycle from concept through detailed design, testing, and validation

Perform DFM trade studies and work with suppliers on manufacturing feasibility, primarily involving machining and additive processes

Collaborate cross-functionally with electrical, manufacturing, test, and flight teams to package and integrate propulsion components into the aircraft
