Job Description:

Our client is looking for a senior reliability leader who will lead reliability requirements for our energy storage product. The individual will lead and define test plans and test methods, sample size, and lifetime definitions, driving the FMEA process to help define priority areas across various aspects of the system. Experience understanding reliability from a material science, physics, electrical and mechanical engineering perspective is critical and experience defining reliability requirements that often would be at the interface of science and engineering is required. The individual would look at reliability right from the start of the concept stage of the product and would need to define reliability requirements along various stages of product development for components and subcomponents that are a part of the energy storage system besides the system itself. You will be working alongside an experienced team of engineers and scientists to build products for a more sustainable future.


Define and drive reliability requirements for the product, subsystem, and components, and first pilot units.
Own design for reliability, define DFMEA, test specs, plan testing and provide clarity on clear pass-fail criteria for various stages of testing in the product development process.
Based on test outcomes, propose/recommend appropriate materials, components, and engineering concepts that minimize or eliminate the risk of failure.
Develop/conduct Design of Experiments (DOE) and reliability studies that would lead to an understanding of multiple variables that may affect product performance and lifetime.
Define field reliability test plans and define testing requirements for warranty analysis.
Ability to do root cause analysis and ability to define solutions that address failure conditions.
Define/establish test methods and statistical process control procedures to achieve desired product reliability.
Evaluate the current manufacturing hardware/software/process and make recommendations for achieving high reliability as the company scales and gears up for increased production and field deployment.
Ability to analyze multiple types of products, subsystem, and component test data and draw conclusions that provides confidence in the reliability of the system.
Ability to carry out statistical analysis to test (accelerated life) and field (life) data to inform reliability physics modeling/analyses.
Build a data-based statistical approach to quantifying reliability where sample size, test criteria, and significance of pass/fail is clearly defined. Determine the statistical sample size required for technical reliability studies.
Define an accelerated testing strategy to ensure that energy storage components are designed to meet product and performance requirements.
Work closely with product management, manufacturing, electrical, and mechanical engineering teams for definition and execution of test plans.


BS/MS/Ph.D. degree in Mechanical Engineering, Electrical Engineering, Physics, or a related technical discipline.
5-10 years of experience in battery hardware design, design validation, hardware testing, mechanical system reliability, and durability testing.
Knowledge of programming in scripting languages for test automation and data analysis/post-processing. Experience in working with large data sets. Experience with Tableau for big data analytics.
Working knowledge of applied statistics and experience with statistical software such as JMP.
Proficient with applying FMEA, DOE, statistical analysis tools to identify failure modes at system, sub-system, and component level
Knowledge and experience with HALT and HASS/ESS for electronic and/or electro-mechanical systems.
Experience specifying sensors for test instrumentation and utilizing data acquisition systems. Knowledge of Battery Management Systems and HV Electronics.
Proven ability to develop reliability and durability test setups including environmental, mechanical, and electrical stress testing highly preferred.
