Electric Motor Design 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.

We are seeking a highly motivated Senior Electric Motor Design Engineer to join our Propulsion team. You will lead the design and development of the HV electric motors for our aircraft’s hybrid propulsion. You will interface across mechanical, thermal, power electronics, airframe, and battery teams to deliver a fully integrated and certifiable hybrid Electric Propulsion Unit (EPU).

• Design, develop, commission, and certify innovative cutting‑edge electric motors for hybrid propulsion system.
• Lead and execute system‑level tests, such as motor and propeller test stands.
• Collaborate with suppliers to ensure delivery of integrated, and certifiable subsystems.
• Perform avionics‑optimized electric motor topology trade studies.
• Create 2D/3D CAD models of electric motors in drawing tools (e.g., Siemens NX).

• 5+ years of professional experience designing high voltage, high power electric motors.
• In depth understanding of permanent magnet motor design, principles, modeling, and analysis techniques.
• Proficiency with JMAG, Ansys Maxwell, RMxpert, or Motor
  
  CAD.
• Design and optimize electromagnetic active parts for manufacturing and certification.
• Hands‑on experience with integration of propulsion and/or powertrain test stands, including instrumentation, controls, and mechanical assembly.
• Strong understanding of electric motors manufacturing processes such as stator winding, lamination stacking, and stator varnishing.
• Strong knowledge of motor manufacturing, heat treatment, statics, dynamics and mechanics of materials.

• Understanding of certification requirements (EASA CS-23/25 or FAA FAR Part 23/25).
• Knowledge of aerospace airworthiness standards, e.g. DO-254, and DO-160.
• Develop and maintain design failure mode and effects analysis (DFMEA).

• Master’s or PhD degree in Mechanical, or Electrical Engineering or related fields.
