Technical Specialist, Cell Modelling
Elysia Battery Intelligence
Kidlington, Oxford, United Kingdom

Elysia Battery Intelligence is building the intelligence layer for battery storage.

Backed by Fortescue, Elysia combines deep battery R&D with real-time software and cloud-based analytics, turning complex battery data into actionable intelligence across automotive, off-highway and stationary energy storage.

As Elysia continues to grow its cell modelling capability, the business is hiring a Technical Specialist to take ownership of key battery modelling programmes while leading and developing a specialist team of engineers.

This is an opportunity for an experienced cell modeller to remain close to the technical work while taking broader ownership across people, projects, technical standards and customer delivery.

Role

Purpose:

Lead cell modelling delivery across multiple customer programmes, translating complex laboratory and real-world battery data into robust engineering models that can be used across live battery development programmes.

You will lead a team of five engineers, manage competing technical priorities and work closely with customers and internal technical teams to ensure high-quality technical delivery.

The role combines hands-on battery modelling expertise with technical leadership, giving you the opportunity to shape modelling standards, team capability and delivery as Elysia's modelling function grows.
