## Description

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
