System Engineer

Role Overview

The Systems Engineer – High Voltage PowerTrain & Charging Systems is responsible for end-to-end systems engineering ownership of in-vehicle HVPT & Charging system features across vehicle programs. With 7 to 10 years of experience, the role focuses on requirements definition, architecture design, integration, validation, and issue resolution delivered in line with performance, safety, regulatory, and user experience objectives.

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.
