We are backed by strategic investment and product partners such as TDK Ventures and Eclipse Ventures.
We are a team of engineers, operators, entrepreneurs, and partners driven by a shared ambition to set the new performance standard for renewable energy and grid resilience.
About the Role – Staff Reliability Engineer
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 across all aspects of the product life cycle, from concept development through field deployment.
This role sits at the intersection of design, testing, manufacturing, and field operations — with direct influence on architecture decisions and reliability outcomes that matter most. You will creatively apply reliability expertise in a fast-paced, hands-on environment where your work has immediate and measurable impact.
The ideal candidate brings deep technical expertise, a proactive ownership mindset, and the ability to think critically and act decisively in a dynamic startup environment.
What You'll Do
- Take independent DfR ownership for existing subsystem reliability and a lead DfR role for 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 modeling 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 and 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, and cost-down projects
What You'll Bring
- 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 including statistics, data analysis, physics-of-failure, lifetime prediction models, accelerated life testing, and DFMEA
- Demonstrated ability to independently lead product reliability through multiple stages of development
- Proficiency using statistical analysis tools in Python or equivalent for modeling 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 PV solar products
- Hands-on experience designing, executing, and reporting complex electromechanical 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
