About this role

Joby Aviation is hiring a Powertrain Mechanical Engineer, Battery, full-time, on-site in San Carlos, CA, in the eVTOL sector.

Company 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. At Joby, we've been working to make that dream a reality since 2009 and we're now in the final stages of certifying our aircraft with the FAA. With plans to launch our aircraft in the US and Dubai, we're now scaling manufacturing and preparing for the launch of our commercial service.

You will be responsible for designing hardware for various systems that power and control the aircraft. This position requires a relentless drive for engineering excellence and the ability to balance complex competing objectives and priorities. The position will work cross-functionally and be responsible for the entire development cycle from early architecture through production.
