BMS Software Development Engineer

Our advanced energy team at Ford Motor Company is seeking a BMS Software Development Engineer to help establish the foundation for our product execution, safety strategy, and vehicle readiness.

The successful candidate will develop the application-layer control software that determines how a high-voltage battery system behaves, including operating states, high-voltage sequencing, protection, limits, thermal control, diagnostics, and coordination across multiple strings.

Responsibilities:

• Develop and own operating state machines and mode management, including supervisory coordination across multiple controllers.
• Implement high-voltage sequencing: precharge control and completion verification, contactor activation and deactivation, contactor diagnostics including welded and open contact detection, and interlock handling.
• Implement protection strategy: cell and pack overvoltage and undervoltage, overcurrent, overtemperature and undertemperature, isolation loss, and thermal event detection and response.
• Implement current and power limit calculation and arbitration, including derate strategy and coordination of limits across levels of the system.
• Implement cell balancing demand logic and coordinate balancing behavior across modules and strings.
• Implement thermal management control, including actuation, setpoint strategy, and thermal diagnostics.
• Implement aggregation and consolidation of measured and estimated states for reporting at system level, and fault propagation and annunciation to external systems.
• Own diagnostic strategy: fault detection, debounce, classification, storage, clearing, and reporting.
• Integrate and calibrate estimation models delivered by algorithm engineering; own the calibration parameter set and its documentation.
• Develop application software using model-based development with production code generation, plus hand-written C where appropriate.
• Author software requirements and design documentation traceable to system requirements; support safety and security analyses.
• Support validation debug, root cause analysis, and field issue resolution.

Qualifications:

• Bachelor's degree in Electrical, Computer, Mechatronics, Controls, or Mechanical Engineering.
• 5+ years developing embedded application or control software for electronic control units.
• Model-based development proficiency with production code generation, plus working C ability.
• Demonstrated state machine, sequencing, and diagnostic strategy design on a production program.
• Requirements-driven software development with traceability, unit testing, and code review discipline.
• Comfort working directly with hardware, benches, and instrumentation to debug control behavior.
• Strong written and verbal communication skills.
• Ability and willingness to travel occasionally.

Benefits:

• Immediate medical, dental, vision and prescription drug coverage
• Flexible family care days, paid parental leave, new parent ramp-up programs, subsidized back-up child care and more
• Family building benefits including adoption and surrogacy expense reimbursement, fertility treatments, and more
• Vehicle discount program for employees and family members and management leases
• Tuition assistance
• Established and active employee resource groups
• Paid time off for individual and team community service
• A generous schedule of paid holidays, including the week between Christmas and New Year's Day
• Paid time off and the option to purchase additional vacation time.

Salary: $86,600-$144,900 or $99,100-$166,200 depending on the salary grade
