As we scale these advanced electrification initiatives, we are seeking technically strong engineers who can help establish the foundation for our product execution, safety strategy, and vehicle readiness. In this position The Battery Management Controls Software Engineer develops the application-layer control software that determines how a high-voltage battery system behaves: operating states, high-voltage sequencing, protection, limits, thermal control, diagnostics, and coordination across multiple strings. Assignments may include supervisory system-level control software or string-level control software and may shift across the product architecture over the life of the program. The ideal candidate has designed state machines, protection strategy, and diagnostic logic on a production program, works fluently in a model-based development environment with production code generation, and is comfortable debugging control behavior on real hardware. What you'll do... * 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. ## Related Videos - [Cyber Security: Small, and Large!](https://www.wearedevelopers.com/videos/259-cyber-security-small-and-large) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Are Code Reviews Worth It?
