Electric Motor Design Engineer

Heart Aerospace is an electric aviation company focused on electrifying regional air travel through the development of battery-electric aircraft. The company is designing the ES-30, a 30-seat electric regional aircraft intended to serve short-haul routes with zero CO2 emissions, offering airlines a fundamentally lower-cost operating model compared to conventional turboprop or jet aircraft. Heart Aerospace also operates the X1 experimental aircraft as part of its development program to validate core technologies ahead of the ES-30's entry into service. The company's mission is centered on decarbonizing aviation, starting with regional routes where electric propulsion is most technically and economically viable. By targeting short-distance air travel, Heart Aerospace aims to eliminate direct carbon emissions on these segments while making regional connectivity more affordable for both operators and passengers. The company has secured investment from leading venture capital firms aligned with electrification and decarbonization goals, as well as strategic investments from major airlines that have also signed on as early customers. Heart Aerospace was founded in Sweden and has established a presence in the United States, with its listed address in Torrance, California. The company represents a new generation of aerospace manufacturers betting that advances in battery technology and electric drivetrains can transform commercial aviation, beginning with the regional segment where routes are short enough to make today's battery energy density practical.

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 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).

Key responsibilities include but are not limited to:

• Design, develop, commission, and certificate 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).

You'll Bring These Qualifications:

• 2+ 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 MotorCAD.
• 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.

These Qualifications Would Be Nice to Have:

• 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).

Education:

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