Staff High Voltage Battery Mechatronics Test Engineer

We are looking to hire an experienced mechatronics engineer for our HV Battery test team where you will work with passionate and multi-disciplinary engineers while using hardware, firmware, and software tools to validate Tesla vehicle battery products to rigorous internal and automotive-industry reliability standards.

This role influences product design through reliability risk identification and testing. We start at early concept phases, going through product development and launch, and continuing into mass production. The candidate will be responsible for developing test plans, designing and implementing automated test rigs, pushing test samples to failure, and reporting on findings. In addition, as an experienced engineer, you will be put in leadership positions to drive validation programs and manage other engineers.

We are interested in candidates with over 5 years of relevant experience, with priority given to curious and driven engineers that have a proven track record of strong technical problem solving, leadership, communication, and cross-functional collaboration.

• Lead validation of new battery products by identifying risks with the cross-functional team through DFMEA, defining validation plans and schedules, and managing test execution towards milestones such as phase exits and start of production
• Develop test infrastructure including mechanical fixtures, electrical testers, and software libraries to allow other test engineers to effectively execute testing. Past examples include pack-scale impact abuse rig, high power (>500 kW) electrical pack cyclers, and ground-up software libraries for bench-level debug and operation of battery packs
• Design and commission complex automated test rigs that involve electrical, mechanical, instrumentation, and software elements
• Draft organized and clear engineering documentation from schematics and drawings, to test plans and test reports
• Devise novel test strategies to derisk new technologies
• Manage and delegate work to junior engineers. Mentor them on technical subjects and check the integrity of their work
• Communicate with engineering leaders the status of a validation program, risks, and failures discovered from testing
• Step in to resolve critical issues and make decisions to help the cross-functional team move past roadblocks
• Investigate test and field failures to resolve design deficiencies and improve test coverage

• Degree in Mechatronics, Electrical, or Mechanical Engineering, or 5+ years of equivalent experience
• Strong understanding and demonstrated experience of most of the following: digital electronics, measurement and instrumentation, data acquisition, statics, solid mechanics, materials science, fatigue, fluids, heat transfer, failure analysis, physics of failure, accelerated lifetime testing
• Experience designing automation systems, mechatronic systems, mechanical structures, and machinery in 3D CAD software
• Experience designing and debugging analog circuits, digital or embedded systems; experience using electrical test equipment such as digital multimeters, hipot testers, micro-ohm meters, oscilloscopes, signal analyzers; experience with EDA and SPICE software
• Experience with an object-oriented coding language and scripting (Python, C++, etc.) for hardware control and data analysis; experiencing writing software libraries that will be used by others
• Experience creating, and executing design validation plans and test methods to validate performance requirements
• Familiarity with high voltage systems and safe work practices
• Experience leading, and driving technical projects to completion, especially when multiple teams' input and consensus are required
• Comfort with balancing competing priorities and timelines and aligning those prioritizations with cross-functional team
• An appetite for hands-on technical problem solving and first-principles thinking
