Joby Overview

Located in Northern California, the Joby Aviation team has been steadily working toward our goal of providing safe, affordable, fully electric air transportation that is accessible to everyone. Imagine an air taxi that takes off vertically, then quietly and quickly carries you over the congestion below, giving you back that time you’d otherwise spend sitting in traffic. Technology has advanced to the point where designing and operating an all-electric aircraft is completely viable. Our team has been discreetly designing and flight testing this vehicle and is looking for talented individuals to see it through certification and high rate production.


Joby Aviation is seeking a talented power electronics engineer to join our team designing electric aircraft. This engineer will work closely with mechanical, software, and other cross functional teams and contribute towards the design of prototype motor-control inverters and DC/DCs from 0.5-200 kW. This is a hands-on position. Engineers are responsible for seeing their projects through from concept design to delivery and support of hardware. Optimizing designs for reliability, weight, and efficiency will be a focus.


  • Collaborate with mechanical engineers to optimize placement of high power modules/components and bus bars
  • Create clear and readable schematics for power electronics boards
  • Component selection for minimum mass and maximum reliability
  • Work with PCB designers to create reliable and low-weight layouts
  • Write requirements, participate in DFMEAs, create and carry out test and validation plans


  • Strong EE fundamentals, including:
  • 5-10 years designing and developing power electronics, in particular inverters for driving 50kW to 200kW motors
  • Strong grasp of motor control theory for surface and interior permanent magnet machines
  • 3-5 years working in aerospace with a strong background in DO-160 compliance
  • 3-5 years writing embedded software in C for control of inverters and/or other power electronics for aerospace applications
  • 3-5 years working with DO-178B software requirements for aerospace applications
  • Schematic capture and PCB design
  • Experience with component selection
  • Completed (designed/built/tested) high voltage/high power designs
  • Great communication skills
  • B.S. in electrical engineering or related discipline


  • M.S./Ph.D. in relevant discipline with a focus in power electronics
  • Familiarity with Altium Designer
  • Wide bandgap semiconductors
  • Exposure to regulatory certification
  • Design-for-reliability, including use of DFMEA and fault trees
  • Designing for high EMI environments 
  • Battery systems
