Reliability Engineer, Energy Storage (San Francisco)

Overview

Redwood Materials is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recyclingkeeping critical minerals in circulation and driving the energy transition. Founded in 2019, were delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.

Reliability Engineer, Energy Storage

As an early member of a new engineering team, you will be responsible for defining system reliability requirements, generating damage models, and characterizing the reliability of our new product. You will work cross-functionally to define requirements, analyze designs, and design tests to meet high reliability standards in real-world conditions, including both electrical and mechanical failure modes.

Youre a doer, excited about getting your hands dirty and working in a dynamic, fast-paced setting, and want to shape a new department at Redwood.

Responsibilities

• Define and own the reliability strategy for hardware products with complex PCBAs and electromechanical assemblies
• Plan and execute reliability tests such as HALT, thermal cycling, vibration, drop, humidity, ingress protection (IP) testing, and power cycling
• Collaborate with cross-functional teams to define design-for-reliability (DfR) requirements and drive root cause analysis for test failures
• Track reliability KPIs and deliver reliability insights to guide design improvements and product decisions
• Develop accelerated life test models and support FMEA and DFMEA processes
• Analyze reliability data using Weibull, log-normal, and other statistical models to predict field performance
• Work closely with engineering teams to establish reliability gates through program stages (A/B/C/D)
• Support failure analysis (FA) efforts using tools like X-ray, cross-sectioning, and SEM/EDX to identify failure mechanisms in PCBAs
• Contribute to continuous improvement efforts across reliability processes, lab capabilities, and test methodologies
• Author reports and document findings

Desired Qualifications

• Bachelors or Masters degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field
• 5+ years of experience in hardware reliability engineering, preferably in energy, EV, consumer electronics, or aerospace
• Deep knowledge of electronic and mechanical failure mechanisms (e.g., solder fatigue, corrosion, delamination, sealing failures, thermal expansion mismatch, material fatigue, etc.)
• Proficiency in statistical analysis tools (e.g., Minitab, JMP, or Python)
• Experience with reliability lab equipment and test setup design
• Knowledge of reliability warranty analysis and reliability prediction methods
• Working knowledge of failure analysis techniques such as optical microscopy, SEM, CSAM, X-ray, cross-sectioning and EDX

Physical Requirements

• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other applicable standards, including meeting productivity standards
• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other applicable standards

Working Conditions

• Office or outdoors environments
• Ability to work in challenging conditions including exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods
• Essential physical requirements such as climbing, standing, stooping, or typing
• Occasional weekends, nights, or on-call as part of the job

In accordance with pay transparency laws, the salary range for this position is $112,250 - $151,750 USD. Actual compensation may vary based on experience, education, and skills.

The position is full-time. Compensation will be commensurate with experience.
