Electric Motor Design Engineer or Senior Engineer

Zunum Aero has an immediate opening for a highly experienced electric motor design engineer for development of hybrid-electric powertrain for regional aircraft. Candidate must have at least 5 years of experience with different types of high efficiency motors, preferably in aviation, or with high-power mobile applications.

Zunum is an emerging leader in hybrid-electric propulsion for aircraft; this position is a unique opportunity to work with a small, dynamic team of dedicated engineers on the next generation of aircraft propulsion. Position is full time, and located in northern Illinois; compensation DOE.

Roles and Responsibilities:

Tasks include, but are not limited to:

  • Participate in the development activities of an electric motor integrated with a propulsor for an electrically driven quiet ducted fan from initial motor design through qualification and certification
  • Execute trade studies for optimum motor topology for torque production and fan speed requirements
  • Participate in the sizing, design, development and integration of components and subsystem comprising the electrical powertrain
  • Collaborate with other disciplines to produce a mechanically sound design including the rotor dynamics stability, power conversion effects on the bearing system and on the stator windings and insulation system
  • Collaborate on the motor cooling approach and oversee the testing and qualification
  • Document component and subsystems requirements and/or specifications
  • Collaborate to develop and execute the engineering project plan for rapid product development


  • Detailed knowledge of the electromagnetic design rules and limitations of Axial Flux, Radial Flux machines and Halbach Arrays.
  • Trade motor architectures and topologies with particular emphasis on high-efficiency low torque-ripple motor topologies, high performance materials, and power density
  • Detailed knowledge of electromagnetic loss calculations and thermal management
  • Knowledge of motor control algorithms utilizing Field Oriented Control techniques and maximum torque-per-amp trajectories
  • Fluency with simulation tools (Matlab Simulink, Pspice, Simplorer or equivalent), power analyzers, and advanced testing and development tools such as dSpace and National Instruments LabView
  • Fluency with both lumped parameter and finite element modeling of electric machines
  • Strong technical writing and presenting


  • M.S. or higher in electrical engineering with 10 years of relevant experience
  • B.S. in electrical engineering with 15 years of relevant experience
  • Technical contributions to the field including patents and publications


  • PhD in electrical engineering with 10 years of experience in aerospace applications
  • First-hand experience with high-efficiency 300-500 kW motors.
