Senior Systems Engineer, High-Voltage Battery Management Systems (HV BMS)

Quick Facts

• Senior Systems Engineer for High-Voltage Battery Management Systems (HV BMS)
• Own system architecture and embedded control architecture for automotive and stationary applications
• Lead safety/security integration and end-to-end traceability for requirements and validation

Description

Own and steer the architecture and implementation of high-voltage battery management systems (HV BMS) for automotive and stationary applications. Translate customer needs into system, hardware, software, safety, and validation requirements, and lead embedded control architecture (including AUTOSAR) to support scalable software, diagnostics, and integration. Drive key BMS functions (SoC/SoH/SoP, cell balancing, contactor control, thermal management, fault diagnostics) and integrate ISO 26262 functional safety and ISO/SAE 21434 cybersecurity, supporting development-to-field issue resolution.

Responsibilities

• Own and steer the complete HV BMS architecture: controllers, system functions, software/hardware interfaces, and safety mechanisms
• Analyze and decompose customer requirements into system, hardware, software, safety, and validation specifications with full traceability
• Define the embedded control architecture for BMS software (including AUTOSAR): application/basic software, drivers, diagnostics, and communication
• Guide software partitioning, resource management, and implementation concepts for scalability and reuse
• Architect and lead core BMS functions: state estimation (SoC/SoH/SoP), cell balancing, monitoring, contactor control, thermal management, and fault diagnostics
• Drive integration of functional safety (ISO 26262) and cybersecurity standards into the system architecture
• Support safety analyses (FMEA, FTA) and ensure compliance with relevant industry and customer regulations
• Provide technical leadership and define/review system interfaces for integration into battery packs, vehicles, and test environments
• Lead complex debugging and root-cause analysis across domains, including field incidents
• Serve as senior customer-facing technical contact for design reviews, workshops, and stakeholder alignment

Requirements

• Bachelor’s degree in Electrical, Computer, or a related engineering field (Master’s preferred)
• 10+ years of embedded control systems experience with substantial direct HV BMS involvement
• Proven real-world HV BMS deployment experience in automotive/commercial vehicle/BESS applications across the full development lifecycle
• Deep HV BMS architecture knowledge (master/slave controllers, AFEs, SOC/SOH/SOP, cell balancing, contactor control, pre-charge, HV safety strategies)
• Embedded C and AUTOSAR proficiency (MCAL, diagnostics, communication stacks)
• Embedded communications experience: CAN, LIN, SPI, Ethernet; UDS diagnostics and calibration concepts
• Hardware/systems knowledge for sensing circuits, power supplies, and high-voltage design considerations (creepage, clearance)
• Working knowledge of ASPICE and safety/security standards (ISO 26262, ISO/SAE 21434) plus FMEA/FTA methods

Benefits

• Competitive compensation and comprehensive benefits package
• Premium health coverage
• 401(k) with generous matching
• Ample paid time off and parental leave
• Life and disability protection
• Employment contingent on successful drug screen and background check
