Responsibilities

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.
Support the engine calibration strategy by defining test plans, calibration methodology, and acceptance criteria across dynamometer, bench, and flight test campaigns.
Perform ECU configuration and tuning (including fuel mapping, ignition timing, and injector phasing) to optimize engine performance, fuel efficiency, and reliability across the operating envelope.
Analyze and deliver torque, power, and fuel consumption results, identifying calibration or hardware improvement opportunities and driving corrective action.
Lead troubleshooting and root-cause investigations for engine testing for the development team and production teams.
Reduce and interpret test and flight data to validate performance against requirements, closing gaps between design intent and measured behavior.
Represent engine calibration and performance in design reviews, technical readiness checkpoints, and cross-functional discussions with design, controls, and flight test teams.
Develop and maintain calibration documentation, procedures, and performance reporting to support program milestones.
Support refinement of performance models for the propulsion system and the vehicle through targeted test campaigns and data review.
