Purpose of the Role

Join Agratas – Where Innovation Meets Impact

Job Title: Characterisation Scientist (X-ray Technique Specialist) – Li-ion Battery Cell (Advanced Characterisation)
Location: Oxford, UK

The Opportunity

At Agratas, a Tata Group enterprise, we are developing world-leading lithium-ion battery technologies to power the transition to a net-zero future. As a Characterisation Scientist (X-ray Technique Specialist), you will play a critical role in unlocking material and component insights through advanced X-ray analysis—including XRD, XRF, and tomography.

This hands-on role is central to our R&D efforts in Oxford, supporting the development and validation of high-performance, next-generation battery materials. You'll work with state-of-the-art tools, collaborate with internal experts and external partners, and help evolve Agratas' in-house analytical capabilities.

If you’re driven by technical depth, data accuracy, and real-world impact, this is your opportunity to help shape the energy storage technologies of tomorrow.

Key Responsibility Areas

• X-ray Characterisation
  Lead the application of X-ray diffraction (XRD) to analyse Li-ion active materials and electrodes. Support additional characterisation through XRF and X-ray tomography on components and small prototype cells.

• Sample Preparation & Analysis
  Prepare solid and liquid samples for X-ray analysis. Conduct experiments, process data (e.g. using Highscore, GSAS), and generate actionable insights for R&D teams.

• Lab Operations & Equipment
  Maintain and calibrate X-ray instruments. Ensure compliance with safety protocols, assist with Radiation Protection procedures, and support laboratory best practices.

• Collaboration & Insight Delivery
  Work closely with electrochemists, scientists, and engineers to deliver meaningful interpretations that accelerate materials development. Build links with external partners and university facilities to access novel techniques.

• Documentation & Reporting
  Maintain accurate experiment records, support method development, and contribute to internal knowledge sharing across R&D.
