Ampira Energy is recruiting a Battery Systems Engineer for a leading industrial energy storage client operating across the UK. This contract role supports the design, development, and deployment of grid-scale Battery Energy Storage Systems (BESS). The successful candidate will bring hands-on experience in battery cell characterisation, BMS development, or BESS system integration, and will contribute to a programme that is directly supporting the UK's net-zero transition.
Key Responsibilities
- Design and develop battery energy storage systems (BESS) for grid-scale and industrial applications
- Lead or support Battery Management System (BMS) development and validation activities
- Conduct battery cell characterisation, testing, and performance analysis
- Perform system-level integration and commissioning of BESS installations
- Develop and maintain battery system models for performance prediction and optimisation
- Produce technical documentation including system specifications, test plans, and safety assessments
- Support compliance activities against relevant standards (IEC 62619, BS EN 62933, UL 9540)
Essential Requirements
- Degree in Electrical Engineering, Chemical Engineering, or a related discipline
- Proven experience in battery systems engineering — BESS, EV, or aerospace battery applications
