Responsibilities

• Architect and develop robust battery management system (BMS) algorithms applicable across different programs and product lines.
• Develop algorithms covering battery state handling, enable/disable switch control, cell balancing, state-of-charge (SOC), state-of-health (SOH), state-of-power (SOP) power limits, communications/drivers, fault handling, isolation monitoring, HVIL, and related functionality.
• Collaborate with battery systems engineers to translate system-level requirements into actionable software and validation requirements.
• Work with battery test engineers and systems engineers to characterize battery cell equivalent circuit models and implement them in BMS software.
• Rapidly develop and validate BMS algorithms in Simulink using test harnesses and battery model simulations or logged data.
• Implement automated software regression testing to improve long-term SIL/HIL testing efficiency.
• Utilize Simulink-to-C auto code generation to convert functional algorithms into compiled artifacts and integrate them into the existing firmware codebase.

Required Qualifications

• Bachelors Degree in Electrical Engineering, Software Engineering or Computer Science
• Demonstrated deployment of robust Battery Management System software or firmware to a multi-cell battery module or pack
• Experience in BMS hardware/software validation methods, including SIL/SITL, MIL/MITL, and HIL/HITL testing
• Proficient C coding for embedded systems
• Experience integrating microcontrollers with analog and digital sensors
• Experience developing firmware in bare-metal or RTOS environments
• Experience in cell equivalent circuit model (ECM) development for BMS
• Experience in battery characterization methods (mission profile validation, ECM characterization, cycle/calendar life, safety features, etc.)
• U.S. Person status due to access to U.S. export controlled information or facilities

Preferred Qualifications

• Graduate degree in Electrical Engineering, Software Engineering or Computer Science with an applied focus on battery management systems
• Familiarity with electrochemical energy storage materials, technologies, and operating boundaries
• Experience in battery testing, modelling, controls, and module/pack integration/operation
• Debugging skills with JTAG, SWD, oscilloscopes, and logic analyzers
• Experience with Simulink model development and auto code generation
