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 ## Skills ### Required - Model-based development - Embedded C application software - State machine and mode management design - High-voltage sequencing and contactor control - Protection strategy and limit arbitration - Diagnostic strategy design - Thermal control strategy - Balancing demand logic - Calibration and parameter management - Requirements traceability and software documentation - Bench and hardware debug ### Nice to have - Master's degree in Electrical Engineering, Controls, or a related technical field - Battery management control software - High-voltage system experience - Software development under functional safety process requirements - Calibration methodology and parameter management for production programs - Coordination or aggregation logic across distributed controllers - Thermal management control strategy experience --- Source: [Apply at efds.fa.em5.oraclecloud.com](https://efds.fa.em5.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX_1/job/69288?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
