Battery Management System Architect

• At Ford, we are the movers of the world and the makers of the future. We get up every day, roll up our sleeves, and build a better world - together.
• In this position...
• 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.
• 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.
• 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
• You'll have...
• Bachelor's degree in Electrical, Electronics, Computer, Mechatronics, or Systems Engineering.
• 6+ years in embedded electronic control system development, including 3+ years on battery management or comparable high-voltage electrical systems.
• Demonstrated ownership of system architecture and requirement decomposition on a production program, including requirement release to multiple suppliers or programs.
