Purpose of the Role Sr. Electrode Design Engineer – Cell Design Location: Oxford, UK Department: Cell Technology / Cell Design Reports To: Cell Design Manager – Cell Technology / Cell Development The Opportunity Join Agratas, Tata Group’s global battery business, and help build the next generation of high-performance lithium-ion batteries. As a Senior Electrode Design Engineer, you will be responsible for leading the design, development, and optimization of electrode structures, enabling innovative and scalable battery solutions. This role will be central in defining electrode compositions, collaborating with cross-functional teams, and ensuring designs meet both electrochemical performance and manufacturing processability targets. You will also guide junior engineers and play a key role in technical strategy and execution within our Oxford-based R&D Centre. Key Responsibility Areas Electrode Design & Development Lead test plans and DOE execution to optimise electrode performance, processability, and design robustness. Finalize electrode compositions aligned with product targets and manufacturing feasibility. Material Selection & Specification Evaluate and down-select electrode components (active materials, binders, conductives, foil) based on performance, cost, and manufacturability. Act as a subject matter expert in supplier discussions and validation. Process Integration & DFM Collaborate with process engineers to align electrode designs with manufacturing processes and throughput targets. Integrate Design for Manufacturability (DFM) into all development phases. Innovation & Problem Solving Drive continuous innovation in electrode structure, materials, and coating techniques. Lead root cause analysis and implement improvements based on electrochemical and mechanical performance data. Leadership & Collaboration Mentor junior engineers and coordinate small technical teams. Collaborate closely with R&D, process, and product teams to ensure timely and aligned development milestones. Documentation & Risk Management Support DFMEA/PFMEA development and maintain high standards in technical reporting, specifications, and validation results. Job Context What You’ll Bring Technical Expertise In-depth knowledge of Li-ion cell design, especially electrode structure and its impact on cell performance and manufacturability. Expertise in performance analysis, failure analysis, and electrode testing methods. Industry & Process Knowledge Experience working with APQP milestones and developing material and process specifications. Broad knowledge of electrode manufacturing processes from lab-scale to pilot/prototype levels. Analytical & Communication Skills Proficient in data analysis, modelling, statistical design of experiments (DOE), and technical reporting. Strong stakeholder communication and cross-functional teamwork. Leadership Capability Experience mentoring or line-managing engineers. Proven ability to lead through influence and manage cross-disciplinary challenges. Qualifications Education: PhD or Master’s in Cell Design, Materials Science, Electrochemistry, or a related field. Experience Extensive hands-on experience in Li-ion battery electrode development. Track record of transitioning designs from R&D to prototype scale, with DFM in mind. Why Join Agratas? Agratas is driving the global energy transition by building cutting-edge battery cell technologies. Backed by the Tata Group, we combine the agility of a startup with the strength of a global enterprise. You'll be part of a growing, world-class team at our flagship Oxford R&D Centre, contributing to technologies that will power EVs and energy systems of the future.
