Job Description

We are seeking a Propulsion Performance Engineer to own engine calibration and performance for the reciprocating engines that power the V-BAT platform.

This role serves as the technical owner for engine calibration strategy — driving test plans, ECU tuning, and performance analysis from bench through flight test — and is accountable for the torque, power, speed, and fuel efficiency characteristics the engine delivers across its full operating envelope.

You'll work hands-on with engine hardware, electronic fuel injection and engine control systems, and engine test stands, creating and executing engine testing strategies under the direction of senior staff propulsion engineers.

Candidates with a background in air-cooled or aviation two-stroke engines are especially encouraged to apply; at minimum, we're looking for someone with deep hands-on experience on reciprocating engines (four-stroke or two-stroke) who can own calibration decisions with minimal oversight.
