Sr. Electrical Design Engineer

Role Overview

Job Description – Senior Electrical Design Engineer

The Electrical Systems Engineer is responsible for the design, development, integration, and validation of electrical and electronic systems for off-highway machines. The role involves system architecture development, high-voltage system design, electrification solutions, power distribution, and electrical component integration across the complete product lifecycle from concept to production.

The engineer collaborates with cross-functional teams including mechanical, controls, software, manufacturing, and validation teams to deliver safe, reliable, and regulatory-compliant electrical systems.

Key Responsibilities

• Electrical System Architecture & Design
• Design and develop complete electrical architecture for machines and vehicles including HV/LV systems.
• Develop system architecture for battery packs, power distribution units (PDU), traction drives, inverters, converters, and auxiliary systems.
• Lead electrical design activities for machine electrification, motor drives, switchgear, and power systems.
• Develop electrical schematics, wiring harness layouts, and component packaging using electrical CAD tools.
• Define system-level requirements, electrical interfaces, and component specifications.
• Design and integrate HV battery systems, traction motors, inverters, and charging systems.
• Develop HV safety architecture including HVIL, insulation monitoring, pre-charge circuits, and battery disconnect units.
• Support electrification initiatives for mining equipment.
• Electrical Component & Subsystem Development
• Develop PDU design, HV/LV wiring harnesses, and electrical distribution systems.
• Integrate CAN-based vehicle networks (CAN J1939) for system communication.
• Develop CAN DBC files and diagnostic strategies.
• Conduct system diagnostics using tools such as CANalyzer, PEAK CAN, and other diagnostic platforms.
• Perform electrical load analysis, power system studies, and fault simulations.
• Conduct short circuit analysis, arc flash studies, and transient analysis using tools such as ETAP and MATLAB.
• Evaluate thermal behaviour and energy efficiency of electrical systems.
• Develop Design Validation Plans (DVPSR) for electrical systems and components.
• Perform HIL testing, functional safety validation, and EMC/EMI testing.
• Support New Product Development (NPD) programs from concept to production.
• Conduct DFMEA, DFMA, risk analysis, and design reviews.
• Collaborate with global engineering teams on product development initiatives.
• Support prototype builds, testing, and field validation activities.
• Cross-Functional Collaboration
• Support supplier development, component sourcing, and technical reviews.
