Cell Testing Engineer

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 hardworking, innovative, and passionate engineer to help take our cell testing to the next level.

This person will be part of the team focused on developing and quantifying the performance metrics unique to EVTOL applications and be engaged in all levels of cell-testing, including design-of-experiments, test protocol development, and data analysis and interpretation.

This person will be integral to driving insights that impact design decisions related to the battery architecture and will work closely with design, safety, electrochemical, and simulation engineers to make our design the best in the industry.

• Develop novel and targeted methods of characterizing cell performance as they relate to aircraft performance and regulatory requirements
• Define comprehensive performance criteria for new cell designs, encompassing electrochemical, mechanical, and safety requirements, in partnership with internal engineering teams
• Own test planning and execution for validation of new cell technologies, root-causing of degradation/failure mechanisms, and battery algorithm certification
• Actively monitor data, trouble-shoot tests and equipment, and use data manipulation and visualization skills (e.g., Python, MATLAB) to effectively convey complex model and test results to fellow engineers and cross-functional teams
• Process data for parameter estimation and develop simulations and models to conduct sensitivity studies for cell design relative to aircraft performance metrics such as range, lifetime, and product value
• Synthesize complex technical test results into clear, program-level impacts and support key engineering decisions by acting as the primary point of contact across internal and external organizations
• MS or above in in materials science, chemistry, electrical engineering, or related field
