Principal Power Electronics Engineer

Zunum Aero has an immediate opening for a highly experienced principal power electronics engineer for development of hybrid-electric powertrain for regional aircraft. Candidate must have at least 15 years of experience with power electronics, preferably in aviation, or with high-power mobile applications. Candidate should be knowledgeable in electric motor driven fans.

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 Kirkland, Washington or northern Illinois; compensation DOE.

Roles and Responsibilities:

Tasks include, but are not limited to:

  • Lead the development of the Electrical Power Train of a fully integrated, electrically driven, low pressure, quiet ducted fan from initial design through final certification
  • Lead trade studies for an electrical system architecture that is consistent with the company’s strategic roadmap
  • Architect and oversee the sizing, design, development and integration of components and subsystem comprising the electrical power train
  • Oversee the development of specifications of component and subsystems
  • Evaluate and select components and subsystems suppliers
  • Develop the engineering plan and work with Project Engineering for flawless execution
  • Be the main presenter and advocate for the design and development in all program reviews (PDR, CDR, Qual Review, etc).


  • Candidate is required to have detailed hands on experience in the design and development high frequency power converters with emphasis to high power high switching frequency AC/DC conversion.
  • Detailed knowledge power switching device types and technologies knowledge such as silicon IGBT’s SiC MOSFETS and the decisions trades to select each.
  • Trade power circuit topologies with particular emphasis on high efficiency multi-level inverter modules
  • Detained magnetic design capability with emphasis on high efficiency low loss materials and topologies.
  • Detailed knowledge of power dissipation calculations and device temperature rise.
  • Knowledge of motor torque and speed control algorithms utilizing Field Oriented Control techniques
  • Fluency with simulation tools (Matlab Simulink, Pspice, Simplorer or equivalent), power analyzers, timing analyzers, and advanced rapid prototyping tools such as dSpace and National Instruments LabView
  • Strong technical writing, presenting, and team leadership skills


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