Joby Overview 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 launching our initial commercial service. Overview 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. Responsibilities * Collaborate with the battery design engineering team and other test engineers to perform various Energy Storage and Distribution System (ESDS) performance, reliability, and environmental testing. This includes power/thermal and humidity cycling, vibration & shock, accelerated life testing, and more. * Aid in the integration and maintenance of various ESDS labs including a complete aircraft representative battery lab, as well as various power distribution, power conversion, and battery thermal management subsystem labs. * Perform characterization, qualification, & reliability tests on components of the battery pack (includes contactors, special-connectors, fuses, PCBs). * Organize and maintain the battery test area and equipment while strictly adhering to best practices, proper documentation and safety awareness. * Perform acceptance tests on aircraft representative battery packs and prepare Safety-of-Flight documents. * Work closely with System Engineers to perform battery pack-level verification and validation tests as well as evaluate battery algorithm (SoC, SoE, etc) performance. * Develop formal FAA Certification test plans and procedures with the proper level of instrumentation and data collection capability, such that test results are repeatable and consistent. * 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. * Work closely with other engineers to aid in the incremental automation of pack- & BMS-functional test setup. Required * Minimum Bachelor's Degree in Electrical, Mechanical, Chemical or other relevant discipline with experience working on Battery Packs. * Experience working with high-voltage, high power systems * Experience with high voltage electric vehicle power electronics systems * Experience with environmental stress testing including thermal and humidity cycling, vibration, electromagnetic interference etc * Basic domain knowledge including battery monitoring techniques, cell and pack failure modes and failure mitigation, high voltage safety * Strong data handling, processing, and presentation skills * Positive attitude and willingness to work individually and as part of a team * Excellent problem-solving techniques and analytical ability. * Maintains a clean work-space and inventory of tools and equipment Desired * Experience with Battery Management Systems hardware is a plus * Experience testing hardware to DO-160, DO-311A, SAE, MIL-810 or similar standards * Familiarity with battery pack cycle test equipment. * Experienced with high voltage Lithium-ion battery systems. * Experience with instrumentation (e.g. contactors, current/voltage sensors, thermocouples, accelerometers, strain gauges) and data acquisition.
