About Redwood Materials

Redwood Materials was founded in 2017 to create a circular supply chain for electric vehicles and clean energy products, making them more sustainable and driving down the cost for batteries. We’re doing this by developing and deploying new technologies to increase the scope and scale of recycled and sustainable materials in the global battery supply chain.

Reliability Engineer

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.

You’re 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 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 consistent 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.

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