Job Description

Staff Reliability Engineer

Location: Burlingame, CA (Onsite)

Department: ESS Engineering

Position Type: Full-time

About the Job

Peak Energy is looking for a Staff Reliability Engineer to help scale ESS hardware reliability with a focus on HV electronics, devices, and power conversion. You will work cross-functionally to realize industry-leading reliability in all aspects of the product life cycle from concept development through field deployment. You will creatively apply reliability expertise in a fast-paced, hands-on environment to make an impact where it matters most whether that’s in design architecture, testing, manufacturing, or field operations.

Responsibilities:

• Take independent ownership of reliability for subsystem reliability of current and future products with a focus on HV electronics, devices, and power conversion
• Fully develop reliability test programs (DV, PV, ORT) by leading DFMEA, defining mission profiles, analyzing test acceleration, and specifying test requirements
• Build and contribute to custom Python reliability analysis and modelling tools to automate workflows for life prediction, test design, test/field data, and reporting
• Define reliability requirements and acceptance criteria at key program milestones and clearly communicate risk and reliability confidence to engineering leadership
• Develop physics-of-failure lifetime models and close the loop by performing failure root cause analysis and statistical analyses of test and field reliability data
• Partner with the SIE team and suppliers to verify component quality by overseeing outsourced testing, defining qualification and inspection requirements
• Collaborate across all teams to embed DfR principles into engineering decisions throughout the product cycle. Including early architecture decisions, manufacturing process development, cost-down projects, etc

Minimum Qualifications:

• Bachelor’s or master’s degree in electrical engineering, mechanical engineering, reliability engineering, materials science, or a related field
• 5+ years of experience in hardware reliability engineering in power electronics, high-voltage systems, or consumer electronics
• Strong understanding of reliability engineering principles - statistics, data analysis, physics-of-failure, lifetime prediction models, accelerated life testing, DFMEA
• Demonstrated ability to independently lead product reliability through multiples stages of development
• Proficiency using statistical analysis tools in Python or equivalent for modelling and data analysis
• Strong documentation and technical communication skills — able to clearly present findings and reliability principles to cross-functional and leadership teams
• Ability to think critically and act decisively to efficiently grow reliability confidence in a fast-paced startup environment

Preferred Qualifications:

• Direct reliability experience with high voltage batteries, DC-DC converters, inverters, battery management systems, or P-V solar products
• Hands-on experience designing, executing, and reporting complex, electro-mechanical reliability tests (HTHE, PTCE, HTOE, HALT, vibration, corrosion)
• Experience with PCBA failure analysis tools such as SEM and X-ray
• Experience using DOEs, accelerated life testing, and field failure data to develop physics-based models for design margin analysis and lifetime failure prediction

The salary range for this role is $180,000-$230,000 with actual pay varying based on work location, experience, and skills. Our competitive benefits package includes flexible time off, comprehensive medical, dental, and vision coverage, a strong 401(k) plan, and equity opportunities. Join us to thrive in a supportive environment while making a meaningful impact in the energy sector!
