## Description

Our client is seeking a Senior EV Systems Engineer with 10+ years of relevant experience to support the architecture, integration, commissioning, validation, and continuous improvement of electric vehicle systems.

This is a hands-on senior engineering role focused on vehicle-level integration across high-voltage batteries, electric propulsion, controls, charging, thermal management, hydraulics, low-voltage systems, diagnostics, and vehicle communications. The role will also support diesel-to-electric conversion programs for commercial and heavy-duty equipment.

Responsibilities

 * Lead EV system integration programs from requirements and architecture through commissioning, validation, production release, and field deployment.
 * Develop vehicle-level requirements, system architectures, engineering specifications, bills of materials, and validation plans.
 * Assess diesel-powered commercial vehicles and industrial equipment for conversion to electric propulsion.
 * Integrate batteries, BMS, motors, inverters, chargers, DC-DC converters, vehicle control units, cooling systems, and charging interfaces.
 * Design and review high-voltage and low-voltage electrical architectures, schematics, wiring, grounding, fusing, contactors, and protection systems.
 * Integrate CAN-based vehicle communications, including SAE J1939, diagnostics, and fault-handling strategies.
 * Develop and calibrate controls for propulsion, regenerative braking, charging, thermal management, hydraulics, and auxiliary systems.
 * Perform commissioning activities, functional testing, validation, troubleshooting, and root-cause analysis.
 * Maintain engineering documentation, change control, test records, and technical reports.
 * Work with manufacturing, quality, procurement, software, service, customers, and suppliers.
 * Support design reviews, customer acceptance testing, field troubleshooting, and regulatory or certification activities.
 * Mentor junior engineers and technical staff.
