About the Company
Our client is a rapidly growing lithium-ion battery lifecycle and recycling specialist, helping accelerate the circular economy for electric vehicle (EV) and energy storage batteries.
They work with high-voltage battery systems from EVs and Battery Energy Storage Systems (BESS), providing services including diagnostics, repair, safe handling, repurposing, and end-of-life processing.
Due to continued growth, they are looking for a High Voltage Battery Engineer to support technical operations both on-site and in the field.
The Role
This is a hands-on engineering role working with high-voltage lithium-ion battery systems (400V–1000V+ DC) across EV and BESS applications.
You will play a key role in diagnosing, repairing, safely isolating, and dismantling HV battery systems, while supporting site operations, safety compliance, and technical reporting.
The role involves working in live operational environments, so strong HV safety awareness and RAMS experience is essential.
Key Responsibilities

* Maintain accurate records for EV and BESS assets
Essential Requirements
✔ 3+ years’ experience working with HV lithium-ion battery systems
✔ Hands-on experience with EV battery packs and/or BESS systems
✔ Strong understanding of battery architecture (cell / module / pack)
✔ Experience with Battery Management Systems (BMS)
✔ Knowledge of HV isolation, testing, and fault finding
✔ Experience working under HV safety rules and permit-to-work systems
✔ Ability to write and implement RAMS
Desirable
⭐ Experience working with large-scale BESS installations
⭐ HV Authorised Person (AP) certification
⭐ Experience in battery recycling or end-of-life processing
Benefits
* Competitive salary + overtime opportunities
* Pension scheme
* 20 days holiday + bank holidays
* High-voltage training and career development
* Access to company vehicle
💡 Opportunity:
This role offers the chance to work at the frontline of EV battery lifecycle and energy storage technology, supporting the safe management of next-generation high-voltage battery systems
