On-siteEngineeringFull-time

Calibrate the engine across the full aviation operating envelope: fueling, ignition, idle stability, transient response, knock, and closed-loop strategy on a standalone ECU, with the propeller governor tuned to performance and reliability targets.
Run the engine test program on an instrumented test stand: break-in, bring-up, performance mapping, and endurance/qualification runs that prove each engine flight-ready.
Bring up the integrated engine from assembled hardware through verification: outfit assemblies, prepare systems, diagnose faults, and close out anomalies.
Operate test instrumentation and DAQ: specify and collect required data to drive propulsion system improvements and validation in a safe and traceable manner.
Translate & Present findings: distill, document, and present data to validate requirements, limits, and drive design changes.
Work closely with other teams to refine and improve propulsion systems.
Refined & Develop the break-in, operating, inspection, and maintenance procedures: document and collect the procedures that carry the propulsion systems through test stand runs, ground runs, and flight tests.

Hands-on experience tuning, calibrating, and bringing up EFI piston engine systems: aviation, motorsport, engine-swap, or standalone-ECU backgrounds are strongly relevant.
Experience qualifying or validating engines on a test cell, dyno, or test stand, and ideally through ground and flight testing.
Practical knowledge of aviation and automotive fuels (AvGas, MoGas) and their effect on calibration.
Comfortable working at the bench and on the aircraft, with strong, self-directed troubleshooting instincts.
Strong collaboration skills to communicate verification findings and design feedback clearly across disciplines.
