About this role

ALSO is seeking a Battery Test Engineer to develop and execute comprehensive validation strategies for battery systems in small electric vehicles. You'll move beyond test execution to define what needs testing, design methodologies, build hardware, analyze data, and make critical engineering decisions about product safety and readiness.

What you'll do

  • Define battery validation strategy including safety testing protocols and production sign-off criteria
  • Design test methodologies covering performance, reliability, durability, thermal, and abuse scenarios across mechanical and electrical domains
  • Build, instrument, and debug prototype and test hardware hands-on
  • Own root-cause analysis and failure investigation when systems underperform
  • Design fixtures, automation tools, and test infrastructure to improve quality and repeatability
  • Analyze test data and translate findings into actionable design recommendations and risk assessments

What they're looking for

  • Battery testing and validation strategy
  • Electromechanical system design and troubleshooting
  • Test instrumentation (DAQ, oscilloscopes, power supplies, environmental chambers)
  • Python or MATLAB for test automation and data analysis
  • First-principles problem solving (electrochemical, thermal, mechanical)
  • Test plan development and production readiness assessment
  • Hands-on prototyping and fixture design
  • Supplier and regulatory coordination

Likely interview questions

  • Walk us through a time you owned the complete validation strategy for a complex electromechanical system—from defining what to test through production sign-off. What were the key decisions and how did you handle disagreement with design or program leadership?
  • Describe your hands-on experience building and instrumenting battery test hardware. What instrumentation have you used, and tell us about a time you had to debug unexpected test results.
