About Redwood Materials

we're 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.

Essential Duties

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.

Responsibilities Will Include

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 / document findings

Desired Qualifications

Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field

5 years of experience in hardware reliability engineering, preferably in industries like 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 consistently safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and / or quantitative productivity standards

Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards

Working Conditions

Environment, such as office or outdoors

Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time

Essential physical requirements, such as climbing, standing, stooping, or typing

Occasional work weekends, nights, or be on‑call as a regular part of the job

Occasional travel requirements

Salary Range (California Pay Transparency)

$112,250—$151,750 USD

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