Sr Test Engineer (Energy Storage and Distribution Systems), Powertrain and Electronics

Located in Northern California, the team at Joby Aviation is driven by our goal of creating an affordable, all-electric air transportation system. 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 onwards toward certifying the Joby aircraft with the Federal Aviation Administration, scaling our manufacturing, and preparing to launch commercial service in 2025.

Joby Aviation is seeking a highly organized, passionate individual to join our Testing team. As part of this team as a Sr Test Engineer (Energy Storage and Distribution Systems), you will contribute to the development of flight-critical components and subsystems for VTOL electric aircraft. The Joby Aviation team is made up of extremely talented, hardworking, proactive, and hands-on individuals, operating in a very fast-paced and rewarding environment. We are looking to expand this team with like-minded individuals looking to make a mark in the transportation industry.

• Work closely with Battery Management System (BMS) firmware engineers and perform battery pack-level verification and validation tests to evaluate battery algorithm (SoC, SoE, etc) performance.
• Develop formal test plans and procedures with proper level of instrumentation and data collection capability, such that test results are repeatable and consistent.
• Perform acceptance tests on flight intended battery packs (for flight integration) and prepare flight article documents.
• Collaborate with battery design engineering team and other test engineers and perform various battery pack environment compliance testing. This includes thermal and humidity cycling, vibration & shock, electromagnetic interference, and more.
• Prepare and conduct long term durability tests on the pack mechanical structure.
• Perform characterization, qualification, & reliability tests on components of the battery pack (includes contactors, special-connectors, fuses, PCBs).
• Analyze data collected during the aforementioned tests to generate reports to provide quantifiable feedback to the battery design engineering team that will allow them to optimize their designs.
• Coordinate and lead test kickoff, test preparation, preliminary and critical test review, and data review meetings to align the above activities.
• Organize and maintain the battery test area and equipment, while strictly adhering to best practices, proper documentation and safety awareness.
• Work closely with battery design engineering team and other test engineers to aid in the incremental automation of pack- & BMS-functional test setup.
