Key Objectives
* Support delivery of reliable HVPT and Charging system features from concept through validation.
* Ensure system requirements are clear, traceable, and verifiable.
* Enable smooth integration of ECUs, networks, sensors, and actuators.
Key Responsibilities
* Create, elicit, and document vehicle-level and system-level requirements for Powertrain and Charging system features using JAMA/DOORS.
* Decompose vehicle-level requirements into system-level and ECU-level functional requirements.
* Create and maintain system specifications, feature descriptions, and Interface Control Documents (ICDs).
* Design and validate Battery Pack (HV), Inverter, Motor, and On-Board Charger (OBC) requirements, including signals, messages, LIN schedules, and I/O mapping.
* Collaborate with software, electrical, validation, and vehicle integration teams to ensure consistent feature behavior.
* Support supplier interactions, including requirements clarification and issue tracking.
* Develop validation strategies, test cases, and acceptance criteria for Powertrain and Charging features.
* Participate in bench, rig, and vehicle testing activities and lead issue investigations.
* Track issues, actions, and requirements traceability using JIRA and related tools.
* Ensure system implementations align with functional safety and cybersecurity expectations.
