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:


  • Lead the design, development, and model-based implementation of battery management system algorithms including state of charge (SOC), state of power (SOP), state of health (SOH), balancing, state machine, charging, thermal management, diagnostics, and safety functions, etc.
  • Lead the integration of model-based battery management system algorithm software code to the rest of the embedded system hand-coded software.
  • Lead battery management system algorithm tuning based on application requirements as well as algorithm verification & validation efforts.
  • Interface with battery testing team to design relevant software-in-loop, hardware-in-loop and hardware tests.
  • Interface with battery modeling team to create model-in-loop simulation for virtual testing of battery management system algorithms as well as to support higher level system simulation (e.g. drivetrain simulation or vehicle simulation).
  • Lead the exploration of advanced battery management system algorithms (e.g. SOH estimation using machine learning methods) with deep theoretical understanding.
  • Create algorithm design, flow chart, tuning, verification & validation, and associated documentation.
  • Interface with battery systems & applications teams to ensure proper battery management features are developed in support of expected battery functionality, performance, safety, and compliance.
