Job description

This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

Company Description

At Allye, our innovative smart energy storage systems are redefining the way batteries are designed, connected, distributed, and utilised to the grid. Flexible and modular, our systems are intelligently managed, making energy storage more affordable and accessible for everyone.

Job Description

A software focused role responsible for the development of Allye's battery systems, integrating battery hardware and software for the MAX energy storage system. Lead R&D activities, battery diagnostics and prognostics and the EMS to control batteries, power electronics and related systems.

Lead the CAN control of embedded battery BMS, to support integration, testing and characterisation of repurposed EV battery packs. This includes developing the end-to-end procedure for battery assessment using remote diagnostics and advanced prognostics to determine SoH and SoU (state of usability). The role will lead the qualification of the battery to full integration and development of a unified CAN controller for multiple batteries from a range of manufacturers, SoH and chemistries.

Lead the development and integration of multiple embedded systems, including the BMS, CAN gateway, EMS, AC-DC bi-directional inverters, control and communications modules. As the overall lead, you will coordinate efforts across the team and suppliers to ensure our systems remain at the forefront of safety and performance while delivering full compliance to grid code regulations across a range of countries.

The role is a unique opportunity to lead development, testing and validation of battery system engineering within a rapidly growing and dynamic company. The ideal candidate will have a background in electrical engineering having gained significant experience in their career working on battery systems and integration of electrical architecture for electric vehicles. You will be hands-on and adept at developing new concepts as well as supporting the commissioning and troubleshooting of systems at customer premises.
