Senior Engineer Propulsion - Engine Performance

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.
