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 elicitation and documentation of vehicle and system-level requirements for Powertrain and charging systems features using JAMA / DOORS.
• Decompose vehicle-level requirements into system 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, OBC (signals, messages, LIN schedules, IO mapping) requirements.
• Collaborate with software, electrical, validation, and vehicle integration teams to ensure consistent feature behavior.
• Support supplier interactions including requirements clarification and issue tracking.
• Development of validation strategies, test cases, and acceptance criteria for Powertrain and charging features.
• Participate in bench, rig, and vehicle testing activities and lead issue investigation.
• Track issues, actions, and requirements traceability using JIRA and related tools.
• Ensure system implementations align with functional safety and cybersecurity expectations.
