The HV Battery Management System (BMS) Systems Engineer technically defines, architects, and steers the implementation of high-voltage BMS for automotive and stationary applications. This role merges the responsibilities of a System Architect and a Software System Designer (SW-SD). The architect will translate customer needs into clear system, hardware, software, safety, and validation requirements, ensuring the final product meets customer, project, and regulatory targets. This highly technical role requires significant real-world experience with HV BMS deployments.
Key Responsibilities:System Architecture & Design: Own and steer the complete HV BMS architecture, including controllers, system functions, software, hardware interfaces, and safety mechanisms. Develop scalable architectural views and lead technical decisions for all BMS components.Requirements Engineering: Analyze customer requirements to derive and decompose system, hardware, software, safety, and validation specifications. Translate needs into actionable work packages and maintain full traceability.Software & Control Architecture: Define the embedded control architecture for BMS software (including AUTOSAR), covering application/basic software, drivers, diagnostics, and communication. Guide software partitioning, resource management, and implementation concepts to ensure scalability and reuse.Core Function Steering: Lead the architectural implementation of key BMS functions such as State of Charge/Health/Power (SoX), cell balancing, monitoring, contactor control, thermal management, and fault diagnostics.Safety & Compliance: Drive the integration of functional safety (ISO 26262) and cybersecurity standards into the system architecture. Support safety analyses (FMEA, FTA) and ensure compliance with all relevant industry and customer-specific regulations.Technical Leadership & Integration: Provide expert guidance to hardware, software, and validation teams. Define and review system interfaces and support the integration of the BMS into battery packs, vehicles, and test environments.Problem Resolution: Lead complex technical debugging, root cause analysis, and issue resolution across all system domains, from development to field incidents.Customer & Stakeholder Interface: Serve as the senior technical contact for customers, leading technical discussions, design reviews, and workshops. Clearly communicate complex topics to all stakeholders to ensure project alignment.
