An exciting opportunity has arisen for a Battery Systems Engineer to join a pioneering startup developing next generation battery technology. This is a hands on role for someone who loves building, testing and iterating quickly. You''ll take ownership of battery pack design from concept through to flight, working collaboratively within a fast moving, inventive engineering team. The Battery Systems Engineer will: Design and develop lightweight, high performance battery packs for drone applications. Create and implement effective thermal management solutions for performance and safety. Assemble prototype packs in-house and support development toward manufacturable designs. Design and integrate power electronics and BMS hardware within the overall system architecture. Establish and run test programmes for performance, cycle life, thermal behaviour and safety validation. The Battery Systems Engineer will have: A hands on, practical approach with enthusiasm for building, testing and improving hardware. A degree in Electrical Engineering, Mechanical Engineering or a related discipline. 3+ years'' experience working on battery systems, including pack design and power electronics. Strong understanding of BMS architecture, protection strategies and charge/discharge behaviour. Experience with PCB design tools (Altium, KiCAD or similar). If you enjoy end to end ownership, thrive in a collaborative startup environment and want to help develop cutting edge battery systems for next
