Power Electronics 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 highly motivated Senior Power Electronics Engineer to join our Propulsion team. You will lead the design and integration of the hybrid propulsion, including but not limited to the inverters, motors, HV cables, with batteries, and in parallel with Turbomachinery. You will interface across mechanical, thermal, electrical, and flight control systems to deliver a fully integrated and certifiable hybrid Electric Propulsion Unit (EPU). Key responsibilities include but are not limited to: This role is a Responsible Engineer (RE) who focuses on the integration of power electronics and high voltage electrical systems into our hybrid aircraft. Full ownership over design, fabrication, commissioning, and certification of the hybrid propulsion system. Lead and execute system‑level tests, such as motor and propeller test stands. Collaborate with suppliers to ensure delivery of integrated, certifiable subsystems. Model the electrical and power electronics systems in our high fidelity Digital Twin for optimization of our hybrid mission profile. Perform topology selection trade studies. You’ll Bring These Qualifications: 5+ years of professional experience working with power electronics components. Strong experience in high voltage power electronics design (+800 V) including AC/DC inverters, and DC/DC converters. Strong understanding of HV filter design, grounding analysis, coordination of protective devices. Hands‑on experience with integration of propulsion and/or powertrain test stands, including instrumentation, controls, and mechanical assembly. Extensive experience with Altium/Cadence/similar circuitry analysis (SPICE), gate driver design, and lab work (common tools like oscilloscopes, network analyzers). Experience with C/C++, Python, Matlab/Simulink, or PLECS. Strong knowledge of Avionics communication, ARINC, CAN, and Ethernet. Strong understanding of Microcontrollers, Multicore processors, Firmware Development, and digital power conversion. These Qualifications Would Be Nice to Have: Understanding of certification requirements (EASA CS‑23/25 or FAA FAR Part 23/25). Knowledge of hardware design and airworthiness DO‑178C, DO‑254, DO‑160. Demonstrated leadership qualities through cross‑functional teamwork on challenging problems. Working knowledge of EMI/EMC, underlying physics and specifications, along with best practices for design, and strategies. Hands‑on experience with Matlab/Simulink Auto Code Generation. Education Master’s or PhD degree in Electrical Engineering with focus on Power Electronics, or Power Systems. Base Pay Range:

$147,000 — $184,000 USD
