• Lead the technical development of OBCM embedded software and control integration across the product lifecycle.

• Define and evolve software controls interfaces verification methods and production acceptance criteria for OBCM functions.

• Develop and guide control strategies for AC/DC power-factor correction DC/DC conversion voltage and current regulation power-flow management and bidirectional operation.

• Provide technical direction for control-loop design state machines PWM and modulation sampling protection diagnostics fault handling and real-time behavior.

• Review software architecture C/C implementation algorithms and technical deliverables to ensure safe maintainable testable and production-ready solutions.

• Collaborate with Software Architects SSLEs HWIO hardware systems safety validation calibration and supplier teams to resolve integration issues across software controls power electronics and vehicle interfaces.

• Integrate OBCM software with battery-management high-voltage charging thermal-management and supervisory-control systems.

• Lead root-cause analysis and resolution of complex issues identified in simulation software integration hardware testing and vehicle testing.

• Establish and lead verification and validation activities across SIL HIL bench dyno and vehicle environments including automated testing and calibration support.

• Maintain requirements traceability from system and software requirements through implementation and test evidence.

• Ensure compliance with functional-safety diagnostic cybersecurity regulatory quality and applicable coding-standard expectations.

• Support technical planning backlog refinement estimation risk management and resolution of critical product issues.

• Mentor engineers and provide technical guidance that improves software quality development efficiency and reuse across applications.

• Evaluate emerging OBCM and power-conversion technologies and lead advanced engineering activities that produce production-ready solutions.

Your Skills & Abilities (Required Qualifications):

• Bachelors degree in Electrical Engineering Computer Engineering Software Engineering Controls Automotive Engineering or a related discipline.

• 5 years of experience in OBC OBCM automotive power conversion embedded controls software or closely related technology.

• Demonstrated experience taking embedded software or controls from requirements through implementation validation and production release.

• Strong hands-on experience with embedded C/C and real-time software development.

• Working knowledge of AC/DC conversion PFC DC/DC conversion voltage and current regulation PWM sampling protection and control-loop stability.

• Ability to analyze software and controls behavior across the controller subsystem and vehicle levels.

• Experience with software and system requirements interface definition verification methods and requirements-to-test traceability.

• Strong system-level troubleshooting skills across software controls hardware power stages and vehicle interfaces.

• Excellent technical communication collaboration and problem-solving skills.

• Ability to work independently lead through influence and make sound technical decisions in a complex cross-functional environment.

What Will Give You a Competitive Edge (Preferred Qualifications):

• Masters degree in Electrical Engineering Computer Engineering Software Engineering Controls Automotive Engineering or a related discipline.

• 8 years of experience in OBC OBCM automotive power conversion embedded controls software or closely related technology.

• Direct experience launching a production automotive OBC or OBCM.

• Experience with bidirectional charging V2G/V2H EV charging interfaces or charging communication standards.

• Experience with SiC-based high-voltage power electronics.

• Knowledge of functional safety diagnostics fault management high-voltage safety and automotive cybersecurity.

• Experience with SIL HIL automated validation calibration dyno and vehicle-level testing.

• Experience with control modeling simulation or rapid-control-prototyping tools.

• Familiarity with automotive communication and configuration technologies such as CAN LIN Ethernet and ARXML.

• Experience with requirements and engineering tools such as DOORS/DNG Git Jira and continuous-integration environments.

• Advanced degree in Electrical Engineering Power Electronics Controls Computer Engineering or a related field.
