Hybrid: This position does not require an employee to be on-site full-time to perform most effectively. The employee’s role enables them to be onsite approximately 3 days per week

The Role:

Welcome to the new era of ELECTRIFICATION!  

Our vision is a world with ZERO Crashes, ZERO Emissions and ZERO Congestion.  We embrace the responsibility to lead the change that will make our world better, safer, and more equitable for all.  We are going to ELECTRIFY the WORLD with exciting new electric vehicles and much more!!

Do you have a passion for coding and take pride in the quality of the software you create?  Consider joining our GM family of Software Engineers in VMEC (Vehicle Mechatronic Embedded Controls).

The VMEC team is comprised of inclusive and diverse Agile teams, where everyone has a voice in the conversation.  Our Software Development process translates Customer requirements into designs, creates code, executes testing, and then integrates our solutions into reality.   Our team’s software is demonstrated in vehicles today like the recently launched Cadillac Lyriq, or the upcoming electric Chevy Silverado and many more.   You can collaborate with the team that has a direct impact on the dramatically growing electric vehicle portfolio and help bring our vision to production.

We are specifically hiring for the Software responsible for the High Voltage Battery State Estimation: This area implements the algorithms responsible for monitoring the battery state of health, such as battery pack capacity, battery limits, and battery pack state of charge based on cell chemistry.  The team also provides voltage, current and power limits for charging and driving, as well as performing active cell balancing of the battery pack for improved efficiency.  Additionally, this team works closely with R&D to help productionize future models and integrate them into production software and with calibration and testing teams to investigate and resolve issues. With new battery cell chemistries new challenges are presented to the Battery State Estimation space: This role will mainly work with Lithium Iron Phosphate (LFP) chemistry-based battery cells.

Please review the Software Engineer role descriptions and required skillsets.  All skillsets are NOT required collectively.  Passion, ability to learn quickly, and interest in the products are important to us!
