Purpose of the Role
The R&D Battery Cell Assembly & Cycling Engineer plays a key hands-on role in the assembly, testing and performance evaluation of next-generation lithium-ion battery cells within Agratas’ R&D facilities.
Working as part of a multidisciplinary battery research and prototyping team, the role is responsible for supporting the build of laboratory and prototype cells, preparing cells for electrochemical testing, operating battery cycling and test equipment, and generating high-quality experimental data to support the development of new battery materials, electrodes and cell technologies.
You will work closely with scientists, technicians and engineers to execute experimental programmes from electrode and component preparation through cell assembly, formation, cycling and post-test analysis. The role requires a strong practical approach, attention to detail and a commitment to producing safe, repeatable and traceable experimental results.
The role will involve working in controlled environments, including dry rooms and glovebox environments, and operating a range of specialist battery assembly and electrochemical test equipment.
The role is located in Abingdon, Oxfordshire, and requires full onsite presence.
