Job description

Motive Workforce is seeking an Electronic/Electrical Engineer to support the design, integration, testing, and production of battery-electric locomotive systems. This hands‑on position will work across electrical architecture, embedded controls, high‑voltage systems, wire harnesses, communication networks, and system testing.

• Support electrical system design and architecture for battery-electric locomotives
• Develop schematics and low-speed PCB layouts for control systems
• Design wire harnesses, cable routing, and electrical interfaces for high-reliability applications
• Develop and integrate embedded controllers using STM32 or similar platforms
• Implement CAN Bus, Ethernet, Modbus, I2C, and SPI communications
• Support electrical systems operating at 1,500V DC and above
• Apply EMC and EMI mitigation techniques within high-voltage systems
• Conduct system and subsystem testing, including automated test development
• Integrate controllers and embedded systems with mechanical and software teams
• Support Linux-based system configuration and embedded software integration
• Partner with production engineering on DFM and production optimization
• Troubleshoot electrical integration and test issues during prototype builds

Qualifications

• Bachelor's degree in Electrical Engineering, Electronics Engineering, or a related discipline
• Three or more years of electrical or electronic systems design experience
• Hands‑on experience with high‑voltage DC systems, preferably at 1,500V or above
• Experience with schematic capture and PCB layout tools, preferably KiCad
• Working knowledge of CAN Bus, Ethernet, Modbus, I2C, and SPI
• Experience integrating embedded controllers and electromechanical systems
• Knowledge of wire harness design and cable‑routing principles
• Experience designing for vibration, temperature, EMC, and EMI requirements
• Basic Linux experience
• Familiarity with automated electrical testing
• Comfortable working in a hands‑on prototype, test, and production environment
• Able to work independently in a fast‑moving engineering organization

Preferred Experience

• Battery‑electric vehicle, BMS, marine, industrial, locomotive, or rail experience
• Safety‑critical systems experience, including ISO 26262 or EN 50126, EN 50128, and EN 50129
• Experience designing EN 50155‑compliant electronic equipment
• High‑voltage electrical safety and protection‑system experience
• Experience taking electrical systems from prototype through production

This position will begin as a project‑based contract and may convert to direct employment based on performance, project demand, and business needs.

Pay Rate: $65.00 to $80.00 per hour, depending on experience
