We are seeking a Battery Testing Engineer to plan, execute, and analyze battery tests at the cell, module, and pack levels. This role is highly hands-on and data-driven, focusing on performance validation, safety testing, and reliability of battery systems throughout development and production phases.

Key Responsibilities

  • Develop and execute test plans for battery cells, modules, and packs, including performance, lifecycle, safety, and environmental testing.
  • Support prototype builds and validation testing.
  • Operate battery test equipment such as cyclers, thermal chambers, power supplies, load banks, and DAQ systems.
  • Analyze test data to evaluate capacity, efficiency, degradation, thermal behavior, and failure modes.
  • Define test procedures, acceptance criteria, and reporting formats in alignment with product requirements and standards.
  • Support abuse, stress, and safety testing (thermal, electrical, mechanical) in controlled lab environments.
  • Investigate test anomalies and failures, perform root-cause analysis, and support corrective actions.
  • Collaborate with mechanical, electrical, and thermal engineers to correlate test results with design assumptions.
  • Maintain test documentation, lab records, and calibration status of equipment.

Qualifications

  • Bachelor’s degree in Electrical Engineering, Mechanical Engineering, or a related field.
  • Experience with battery testing at cell, module, or pack level.
  • Strong understanding of lithium-ion battery behavior, degradation mechanisms, and safety considerations.
  • Hands-on experience with battery test systems and lab equipment.
  • Ability to analyze and interpret large datasets using tools such as Python, MATLAB, or Excel.
  • Familiarity with battery management systems (BMS) and related measurements (voltage, current, temperature).

Preferred Qualifications

  • Familiarity with battery system components and requirements: cells, modules, enclosures, etc.
  • Experience designing test fixtures or instrumentation setups.
  • Experience with automation or scripting for test execution and data processing.

Personal Attributes

  • Detail-oriented and methodical with a strong safety mindset.
  • Curious and analytical, with a passion for understanding battery behavior.
  • Comfortable working hands-on in a lab environment.
  • Strong communicator who can clearly present test results and conclusions.
