  • Analyse test data using tools like Python or MATLAB, draw conclusions, and present clear technical insights
  • Implement and improve validation methodologies, including data automation and traceability
  • Ensure alignment with industry standards, regulations, and customer-specific validation requirements
  • Support failure investigations with structured problem-solving tools such as 8D or Six Sigma
  • Maintain accurate and traceable records of all validation activities
  • Work collaboratively with Cell Design, Test Operations, CAE, and Pack teams to embed validation throughout the development cycle
  • Provide mentoring and technical guidance to junior team members

  • Degree in Engineering, Physics, or a related discipline
  • 3+ years of experience in lithium-ion cell development or validation
  • Hands-on experience validating large-format Li-ion cells
  • Proven track record developing and executing CV/DV/PV test methodologies
  • Strong data analysis skills using Python, MATLAB, or similar tools
  • Confident communicator, able to collaborate effectively across technical teams

  • Experience with failure analysis techniques such as CT scanning, X-ray, or thermal imaging
  • Knowledge of test automation platforms or validation databases
