Purpose of the Role

Senior Cell Validation Engineer

Location: Coventry, UK
Department: Cell Product Ownership & Validation


Powering Progress at Agratas

At Agratas, we’re building a cleaner energy future through advanced battery technologies. As Tata Group’s global battery business, we’re focused on designing and manufacturing high-performance lithium-ion cells for electric vehicles and energy storage. To support our mission, we’re looking for a Senior Cell Validation Engineer to ensure our products deliver unmatched safety, reliability, and performance.

 

The Opportunity

As a Senior Cell Validation Engineer, you will lead the validation of lithium-ion battery cells across all stages of development — from concept through to design and process validation (CV, DV, PV). You’ll be instrumental in turning requirements into robust, data-driven test plans, ensuring our products meet customer, legislative, and regulatory expectations.

You’ll work cross-functionally with teams across design, CAE, test, and pack engineering — playing a key role in analysing test results, solving complex problems, and mentoring junior engineers. This is a unique opportunity to influence the technical quality of next-generation battery technologies.

Key Responsibility Areas

Key Responsibilities

  • Lead planning and execution of validation phases (CV, DV, PV) for lithium-ion battery cells
  • Develop robust test procedures to assess performance, durability, and reliability across a range of use cases
  • 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

 

Job Context

What We’re Looking For

Essential Experience & Skills:

  • 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

 

Desirable Skills:

  • Familiarity with lithium-ion cell design and DFMEA processes

  • Experience with failure analysis techniques such as CT scanning, X-ray, or thermal imaging

  • Knowledge of test automation platforms or validation databases

 

Why Join Agratas?

At Agratas, you’ll be part of something big – helping to deliver energy solutions that have global impact. Here’s what you can expect:

  • A mission-driven company shaping the future of energy storage
  • Opportunities to work on cutting-edge lithium-ion cell technology
  • A collaborative, fast-moving environment that values innovation and technical excellence
  • Support for personal and professional growth, including mentoring and development pathways
