This position is eligible for remote work at the present time. The arrangement may be delayed for training or other job acclimation purposes and remains subject to change. Ideally, the chosen candidate will live near or be willing to relocate to Cary, NC.
John Deere is seeking engineers to help develop lithium-ion battery solutions. John Deere sees demand growing for batteries as a sole- or hybrid-propulsion system for vehicles. Some products in Deere's portfolio such as turf equipment, compact utility tractors, small tractors, compact construction, and road building equipment could rely solely on batteries as a primary power source in the future. Deere intends to continue to invest in and develop technologies to innovate, deliver value to customers, and work towards an electrified future. This is an exciting opportunity to join an innovative leader in precision agriculture and construction equipment and technology solutions as we continue our electrification journey towards a more sustainable future.
Your Responsibilities
As a Senior Battery Management System Controls Engineer for JD Power Systems located in Cary, North Carolina you will:
