• Experience establishing internal engineering ownership of an externally developed electronic system.
• Experience with large series-connected battery systems and production or end-of-line test requirement definition.
• Familiarity with network and bus analysis tools (e.g. CAN/Ethernet traffic analysis, Wireshark) for reviewing supplier communication behavior and diagnosing interface issues.
• Technical Skills
  • System architecture and functional partitioning; product attribute allocation; requirement decomposition and bidirectional traceability; verification strategy, acceptance criteria, and verification level allocation; interface control documentation; operating state and fault handling architecture; measurement accuracy and error budget allocation; functional safety and cybersecurity concept development, FMEA and FMEDA; communication architecture and timing analysis; model-based systems engineering; high-voltage battery and cell-level fundamentals; supplier design assessment and technical review leadership.
    Tools: JAMA and Codebeamer, JIRA, SysML modeling tools, MATLAB/Simulink, CANalyzer/CANoe, GitHub, Python, Wireshark.

 What you'll do...

• Architecture and Requirements
  • Own the BMS architecture and the functional allocation, partitioning, and design rationale across its components and control levels.
  • Own product attribute requirements - usable energy, power and current capability, charge and discharge rate, efficiency, and service life - and allocate them into system, subsystem, and component requirements.
  • Decompose customer, safety, and program requirements with bidirectional traceability; author and release requirement sets across multiple concurrent programs and suppliers, maintaining a common core with program-specific variants.
  • Define operating states and transitions, and the fault handling architecture covering detection, classification, propagation, annunciation, and recovery.
  • Define the internal communication architecture, including message sets, timing budgets, and degraded-mode behavior.
  • Define measurement and accuracy requirements for voltage, temperature, current, and isolation, and allocate error budgets across the sensing chain.
  • Own architectural trade studies and document decisions, alternatives, and rationale. 
• Verification Basis
  • Own the design verification strategy and ensure full verification coverage of released requirements, with methods assigned by requirement class.
  • Define acceptance criteria, test method, level of test, instrumentation, and evidence to be retained; allocate requirements to analysis, simulation, bench, subsystem, or full-system verification.
  • Own requirement-to-verification-to-result traceability and its completeness at each program gate.
  • Review and disposition verification results against acceptance criteria; approve deviations, retests, and resulting requirement changes.
  • Define verification methods for supplier-executed testing and review returned evidence for method conformance and sufficiency.
  • Interrogate test, bench, and field data to assess design performance and close issues to root cause.
• Interfaces, Safety, and Technical Leadership
  • Author and maintain interface control documentation to thermal, power electronics, safety and protection, and higher-level control systems, including software-visible signals, diagnostic, and calibration interfaces.
  • Own the functional safety concept to ISO 26262: hazard analysis and risk assessment, integrity level allocation, safety mechanism specification, diagnostic coverage targets, and the safety argument; support FMEA, FMEDA, and safe state definition.
  • Author cybersecurity requirements in partnership with the owning cybersecurity organization, aligned to ISO/SAE 21434, and cascade them to suppliers.
  • Define interface requirements to externally executed enclosure and packaging design, including board outline, connector position, thermal path, creepage and clearance, grounding, and sealing.
  • Lead architecture and design reviews with internal teams and suppliers; adjudicate technical deviations and concessions.
  • Provide technical direction to hardware, software, controls, and validation engineers, and act as escalation for cross-domain design conflicts.
  • Present architecture status, technical risk, and recommendations to senior management
