About this role

ALSO seeks a Battery Controls Engineer to develop and validate BMS algorithms for electric vehicles, including state estimation, thermal management, and protection strategies. You'll design control systems in MATLAB/Simulink, generate embedded code, and collaborate across teams to deliver production-ready battery management solutions.

What you'll do

  • Design and develop BMS control algorithms for thermal management, charging, and power distribution
  • Develop and validate battery state estimation algorithms (SOC, SOH, SOF) using physics-based or data-driven approaches
  • Design protection strategies including overvoltage/undervoltage, overcurrent, cell balancing, and thermal limits
  • Build and validate system models in MATLAB/Simulink/Stateflow and support MIL/SIL/HIL testing
  • Generate production-quality embedded C/C++ code for microcontroller deployment
  • Analyze field data to refine predictive models for battery degradation and performance

What they're looking for

  • Battery management systems and SOC/SOH estimation
  • Lithium-ion chemistry and electrochemical degradation mechanisms
  • Control theory and state estimation (Kalman filtering)
  • MATLAB/Simulink/Stateflow and model-based development
  • C/C++ embedded systems programming
  • Embedded code generation tools (Simulink Coder/Embedded Coder)
  • Vector tools (CANalyzer, CANape, CANoe)
  • ISO 26262 functional safety standards

Benefits

  • Health, dental, and vision insurance covered up to 100% by employer
  • One Medical membership and dedicated insurance advocates
  • Fertility and family-building benefits through Progyny
  • Flexible time off
  • 401(k) matching
  • Limited remote work flexibility after ramp-up period
