Responsibilities • Modeling and design of mechanical components and assemblies for power electronics converters including plastics, sheet metal, heat sinks, insulation systems, magnetic components, high voltage connectors, fasteners, and other components. • Mechanical design analysis including thermal, CFD, structural, design for assembly, and design for test. • Solve electronics packaging issues including electrical isolation, sealing, thermal management, interconnection, shock and vibration management, electromagnetic interference (EMI), RF communications, etc. • Create drawing packages and manufacturing instructions for parts and assemblies. • Assist in engineering prototype builds and component fabrication. • Collaborate with other mechanical, systems, electrical, firmware, manufacturing, industrial design, and test engineers to take designs from prototype through mass production.

STM (Site Technical Manager) is the single threaded owner for manufacturing technical issues for assigned projects with our Contract Manufacturers, focus on: - Ensure technical readiness for product ramp and serve as manufacturing engineering owner for product PVT and mass production. - Driving manufacture test flow optimization, process and yield improvements to exceed our volume production goals. - Define the manufacture process qualification criteria, manage the qualification activities, and complete the documentation. - Leading our efforts for root cause and corrective action for all manufacturing process related issues, dive deep to analyze the problems found both in and out of the factory. - Participation in design & planning through DFM, Line balancing , as well as Process Yield, Capacity and Cost Modeling. - Work with CM’s engineering teams to identify and escalate manufacturing challenges by enforcing DFM and DFT principles. - Review and approval of Fixtures Designs & Qualification (FATP, Device build) - Review and execute Manufacturing Test Coverage Documents to ensure new products launch. - Work with sustaining engineering team on the opportunities to improve our product, owns the technical readiness of PRQ in CMs. - Periodically audit the CM for manufacture process quality management system.

• Lead testing and verification of power converters, power protection products and DC power distribution systems; develop and maintain stage-specific test plans and protocols per product requirements, design specs and relevant domestic & international standards. • Conduct multi-dimensional tests covering electrical performance, firmware, EMC, safety, reliability and components per schedules; identify and report issues, and support designers in troubleshooting. • Process, analyze and interpret test data to pinpoint potential risks and performance bottlenecks; deliver high-quality test reports & summaries, and maintain the defect database. • Partner closely with the R&D team to root-cause test-identified issues, track progress and drive defect closure. • Ensure agile and cost-effective test execution aligned with project delivery timelines. • Contribute to the development roadmap of the our new innovation lab, and advance its automation and digital transformation. • Establish the R&D test case database and streamlined test workflows to achieve end-to-end test coverage. • Mentor junior technical engineers.

About the team The Industrial Energy team designs the eyes, ears, and brains of Tesla’s Energy Storage (Megapack) products. These system boards control the central processing, communications, thermal systems, high voltage safety, and system level components including breakers, contactors, and pyrofuses. The Role The Industrial Energy team is looking for a skilled and motivated individual to support the development, debug and continuous improvement activities of the Megapack PCBAS and factory test infrastructure. This person will serve as a first line of support to trouble-shoot PCBA failures from factory test as well as field returns. They will also perform sustaining activities such as designing in alternate components, cost-downs and design improvements. This person will interface with PCBA vendors and Tesla staff in the supply chain, factory test, field service and design engineering groups, requiring clear and organized communication. Responsibilities • Troubleshoot Megapack PCBA failures and drive corrective actions. • Start to finish design of tester PCBAs to support factory test stations. • Collaborate on the design and improvement of electronics test infrastructure hardware and software. • Support design updates to Megapack PCBAs. • Develop and execute test plans to validate circuit performance.
