Purpose of the Role

Principal Electrode Process Engineer – Li‑ion Battery Cell Development

Location: Oxford, UK

Function: Cell Development – Electrode Process Development

Reporting to: Head of Formulation and Electrode Manufacturing, Cell Technology & Product Strategy

The Opportunity

Agratas is building the next generation of high‑performance battery technology, and we are looking for a Principal Electrode Process Engineer to play a pivotal role in shaping our electrode development capability. This is a unique opportunity to work at the forefront of Li‑ion battery innovation, collaborating closely with R&D and Cell Development teams to design, optimise, and scale electrode manufacturing processes from laboratory to mass production.

You will lead the formulation of anode and cathode slurries, analyse process and quality data, and drive improvements that directly enhance electrode performance and cell efficiency. As a subject matter expert, you will also support global teams, share best practices, and help build technical capability across the organisation.

This role is ideal for an experieinced Battery Process engineer who thrives in a fast‑paced product development environment and wants to contribute to the future of sustainable energy storage.

Key Responsibility Areas

• Electrode Process Development: Define and optimise slurry formulations, coating parameters, and calendering processes for anode and cathode electrodes. Improve process stability, quality, and throughput across R&D, pilot, and production environments.

Cross‑Functional Collaboration: Work closely with scientists, engineers, and manufacturing teams to troubleshoot issues, develop new processes, and support rapid product development cycles.

Technical Support Across Sites: Act as a global subject matter expert, supporting R&D, intermediate, and mass‑production lines to resolve electrode fabrication challenges.

Process Documentation: Maintain accurate records of process parameters, test results, and development learnings. Communicate findings clearly to R&D and Cell Development teams.

Training & Mentoring: Build organisational capability by training and mentoring engineers and technicians across global locations.
