Power Electronics Engineer

Joby Overview

Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. Since 2009, our team has worked steadily to make this dream a reality. We’ve designed and tested many generations of prototype aircraft capable of serving in a network of electric air taxis.

We’re looking for talented, committed individuals to join our team as we push onward toward certifying the Joby aircraft, scaling our manufacturing, and launching our initial commercial service.

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, on-site position based in San Carlos, CA. 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.

• Create clear and readable schematics for power electronics boards
• Create optimized and reliable layout designs
• Component selection for minimum mass and maximum reliability
• Create optimized and reliable layout designs
• Write board bring-up test plans, execute them and collect data for new boards
• Collaborate with mechanical engineers to optimize placement of high power modules/components and bus bars
• Support manufacturing by troubleshooting critical production issues and designing test procedures
• Participate in detailed root cause and failure analysis

• B.S. in electrical engineering or related discipline
• Strong EE fundamentals, including:
• 3-5 years designing and developing power electronics, in particular, inverters for driving 50kW to 200kW motors
• Understanding of motor control theory for surface and interior permanent magnet machines
• Schematic capture and PCB design
• Experience with component selection
• Completed (designed/built/tested) high voltage/high power designs
• Great communication skills

• M.S./Ph.D. in relevant discipline with a focus in power electronics
• Experience working in aerospace or automotive industries
• Experience working in aerospace with a strong background in DO-160 compliance
• Experience writing embedded software in C for control of inverters and/or other 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
