Our Group
In the Abuse Testing & Engineering group, we push energy storage and power conversion systems to their limits and beyond. Our goal is to understand how robust systems are to abuse, identify weak points and recommend improvements. We accommodate external regulations but have a strong focus on internal requirements and test to failure. We collaborate closely with product design teams, serving as both test engineers and subject matter experts.The Role
We are looking for an engineer to test abusive scenarios that could occur in a manufacturing setting. We produce every component from individual cylindrical cells up to battery packs, and a factory presents a wide range of thermal, electrical, and mechanical hazards. You would collaborate with product and equipment designers as well as the EHS team to assess likely risks, and plan/conduct tests in our runaway-tolerant facilities (with technician support) to evaluate them directly. By aggregating this information across different product lines, you would be a source of truth for battery manufacturing safety hazards, ensuring we build products safely as we rapidly accelerate worldwide production.
  • Serve as point of contact for testing battery safety in a manufacturing setting
  • Tour factories, study production equipment, and understand product designs
  • Create test plans and execute tests, such as dropped products, external short circuits, crush, unprovoked thermal runaway, or pooled conductive fluid
  • Plan and conduct large-scale tests replicating room-level fires and inform sprinkler design
  • Share results and maintain documentation to be easily referenced by other teams
  • Recreate incidents and suggest countermeasures

  • BS or MS in mechanical engineering (possibly electrical or chemical engineering or similar degree). Experience with heat transfer, mechanical, and electrical fundamentals.
  • 2+ years’ experience in physically-applied engineering (lab, machine shop, hobby project…)
  • Must be hands-on (fabrication/modification, instrumentation, sample inspection)
  • Enjoys working in cross-functional groups and leading technicians
  • Experience with instrumentation / data acquisition a plus
  • Able to plan many concurrent activities in a fast-paced, rapidly changing environment
