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
