Senior/Staff Motor Control Software Engineer
About The Position
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. Overview This senior engineer will play a key role in a small, fast-moving team and participate in architecture, design, and implementation of motor control systems within our electric-powered, fly-by-wire aircraft. This engineer will work closely with the hardware, mechanical, integration, and flight-testing teams to design, develop, test and improve system-level behaviors.
