Tesla Reliability Engineer High Voltage Battery 

United States, California, Palo Alto 

464063065

We are looking for a Reliability Engineer for high-voltage batteries with a strong background in batteries on cell, module, or pack-level. In this role, you will play a key role in designing reliability into our powertrain systems for our Tesla vehicles. As a successful candidate, you will follow the reliability lifecycle of these products from concept to design, development, manufacturing, and field operation to design-in, confirm and grow exceptional reliability at every stage.

This role is highly engaging, and you will also be working on one of our most exciting products. You will collaborate with cross-functional engineering teams to understand emerging designs and architectures. You will be responsible for identifying risks associated with these architectures. You will identify appropriate stresses that our products must pass and create test plans, which will be used to assess the reliability of our products. You will provide reliability analyses and suggestions to improve the reliability of our products.

The level of this position will be determined at the time of the interview.

• Apply solid knowledge of reliability methods and battery packs / high voltage systems to design accelerated test plans for design validation, burn-in testing, environmental stress screening (ESS), ongoing reliability testing (ORT), and demonstration of reliability growth
• Analyze field usage and environmental conditions to optimize requirement setting, test methods, and reliability specifications
• Facilitate and lead design FMEA sessions to assess product risks, determine validation test plans and drive reliable design choices
• Work with manufacturing quality, service engineering, supplier quality and design teams to identify root causes and drive resolution for failures originating in testing and in the field
• Generate process validation test plans to implement at suppliers, and drive root cause corrective action with suppliers to resolve production process issues
• Provide reliability design guidelines and apply reliability lessons learned to enable continuous improvement

• Degree in Mechanical Engineering, Material Science, Electrical Engineering or equivalent experience
• 2+ years of experience working on battery systems / high voltage laboratory testing environment (including relevant internship or academic lab work experience)
• Experience with burn-in testing, Environmental Stress Screening (ESS), Ongoing Reliability Testing (ORT)
• Understanding of Highly Accelerated testing methods and governing equations for different types of acceleration models
• Experience with developing reliability guidelines and inventing novel ways of reliability testing
• Working knowledge of reliability statistics including Weibull analysis, and experience with statistical software such as JMP, Minitab, etc.
• Working knowledge of failure analysis techniques such as optical microscopy, SEM, CSAM, X-ray, cross-sectioning and EDX
• Self-driven and focused individual with a proven ability to manage parallel tasks effectively, with a desire to work in a fast-paced environment
• Proven ability to remain engaged, proactive, and positive in tough circumstances
