Senior Engineer - Cell Test

Job Summary

The Cell Product Development team is developing ONE’s battery cells for our rapidly growing business in automotive, grid, and commercial applications. Our objective is to design, prototype, evaluate, and scale-up novel cell product designs with focus on detail, innovation, and pack/systems integration. Successful cell designs will be scaled-up and manufactured in our 20 GWh cell factory in Van Buren Township, MI.

As a Senior Cell Test Engineer, you will develop methods to evaluate and characterize new cell products which considerably improve energy density, power density, DC fast charge capability, safety, and cost over incumbent EV technologies. Your focus will be to develop analysis (analytical, numerical, and empirical), characterization methods, and test plans, to evaluate materials, components, and cell designs, for energy/power density performance, safety performance, structural and thermal performance, DC fast charging, cost down, etc. You will work with suppliers, test/fabrication houses, and various in-house teams at ONE to execute cell and component test plans, to accelerate the time to market for new cell and materials technologies.

We are looking for a passionate individual who shares our values. Our team is comprised of various integrated disciplines, including mechanical, structural, thermal, electrical, materials/chemistry, and software. Therefore, collaboration in group settings, ability to solve system integration challenges, and clear communication are valuable to becoming a successful team member.

You should enjoy working in a small team where you will own substantial and critical parts of the final product. We are working on groundbreaking technologies, so you’ll be energetic, adaptable, and a fast learner who can make quick design judgments with limited information.

Responsibilities

• Develop internal test methods, test plans, and SOPs to characterize and evaluate component/cell designs (sub-scale and full-scale) and grow the cell testing and characterization infrastructure within the team.
• Work with external test houses and internal lab ops teams to execute test plans and ensure that testing conforms to SOPs.
• Routinely execute and analyze tests, including safety and abuse tests, themselves using our in-house test equipment and facilities.
• Continuously identify areas of risk and work quickly to mitigate.

Within 3 months you will:

• Become familiar with the ONE team and internal cell products.
• Become familiar with in-house cell test methods, equipment, and facilities.
• Work closely with ME design teammates to design and fabricate new test fixtures.
• Execute cell and component level tests as required.

Within 6 months you will:

• Take ownership of test execution and analysis and methods development.
• Take ownership of testing and characterization methods development.
• Identify, evaluate, and develop promising internal/external characterization methods and equipment.
• Collaborate with other system disciplines to plan and execute overall project delivery.

Desired Qualifications

You should be familiar with all, proficient with many, and expert at some of the following, in no particular order:

• B.S. or higher in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Materials Science and Engineering, or a related field.
• 5+ years of cumulative experience (academia + industry) in electrochemistry, cell design (Electrodes, stack, enclosure, end caps, terminals, vents, etc.), thermal and structural materials and analysis, cell testing and characterization, cell manufacturing, and cell safety.
• Experience in developing testing and characterization methods for multi-functional hardware components.
• Test methods and fixture development for safety and abuse testing, DC fast charge testing, etc.
• Experience with UN38.3, UL1642, GB/T 38031-2020, UN/ECE 100-03 testing standards.
• Comfortable working in a fast-paced R&D environment.
• Strong written/verbal communication and organizational skills.
• Successful candidates will have meticulous attention to detail, possess outstanding problem-solving skills, and have considerable hands-on laboratory and/or factory experience.

We welcome you to apply even if you don’t match every requirement posted for this role. No one candidate will be a 100% perfect match to our description, so if you are passionate about working on decarbonizing energy and have similar experience to what we are looking for, we encourage you to apply. Diverse backgrounds and experiences promote innovation, and our goal is to build a team that encompasses a variety of backgrounds, experiences, and skills.
