About this role

Propulsion Test Engineer Los Angeles, CA At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade. Your Mission We are seeking a Propulsion Engineer to join our Dynamic Propulsion team in Torrance, CA. You will lead the testing, validation and certification of the aircraft's hybrid-electric powertrain system. You will also interface across mechanical, thermal, propulsion, actuation, avionics, and battery teams to develop, execute, and analyze integrated system-level tests of the Electric Propulsion Unit (EPU) and its subsystems. Key responsibilities include but are not limited to: - Lead and execute system-level powertrain testing, including electric motor, inverter, gearbox, disconnect systems, and propeller subsystems. - Design and commission hybrid-electric propulsion test stands, HIL, and Digital Twin, including instrumentation, safety systems, control systems, and data acquisition. - Plan, execute, and document test campaigns to verify performance, safety, and certification compliance. - Collaborate with cross-functional teams to develop test procedures and test plans for integrated propulsion systems. - Coordinate with suppliers and external labs to support component and system-level testing. - Analyze test data, prepare reports, and provide feedback to design teams for iterative development. - Support environmental, endurance, fault-injection, and compliance testing for certification readiness. You'll Bring These Qualifications: - 2+ years of professional experience in powertrain, propulsion, or test engineering, with electric or ideally hybrid-electric systems.
