Job description

About the Role

We’re looking for a skilled Electronic/Electrical Engineer to collaborate on the design of our battery electric locomotive. This is a hands‑on role where you'll work across the full electrical system lifecycle—from design and integration to testing and production optimization.

We want a driven, fast‑paced self‑learner who thrives in multidisciplinary environments and isn't afraid to take on technical challenges in a rapidly growing company.

We offer a competitive salary, comprehensive benefits, and the opportunity to shape the future of rail technology while building a generational multi‑billion dollar company.

What You’ll Do

• Collaborate on system design and architecture for a battery electric locomotive
• Partner with production engineering to optimize designs for manufacturing (DFM)
• Develop schematic designs and low‑speed PCB layouts for control systems
• Design wire harnesses and cable routing for high‑reliability applications
• Implement robust communication protocols including CAN Bus, Ethernet, ModBus, and board‑level protocols (I2C, SPI)
• Design controllers and embedded systems for harsh industrial/automotive/locomotive environments
• Conduct system and subsystem electrical testing, including automated test developmentIntegrate embedded systems and controllers with mechanical and software teams
• Implement EMC mitigation strategies for high‑voltage DC systems
• Support embedded software integration and Linux‑based system configurations
• Ensure electrical safety in high‑voltage DC environments (up to 1500V+)

What We’re Looking For

• 3+ years of experience in electrical/electronic system design (automotive, marine, industrial, or rail preferred)
• Hands‑on experience with high voltage DC systems (1500V+)
• Proficiency in schematic capture and PCB layout tools - we use KiCAD
• Experience with communication protocols: CAN Bus, Ethernet, ModBus, I2C, SPI
• Understanding of embedded systems and controller integration - we use STM32
• Familiarity with design techniques for harsh environments (vibration, temperature, EMC/EMI)
• Basic Linux experience and comfort with automated testing concepts
• Knowledge of wire harness design and routing principles
• Experience with EMC/EMI mitigation techniques
• Nice to have: Safety‑critical system design experience (ISO 26262, EN 50126/8/9, or similar)
• Ability to thrive in fast‑paced, high‑pressure startup environments
• Proactive self‑starter who can execute with minimal supervision
• Passion for clean energy and sustainable transportation
• Bonus: Experience with battery electric vehicles, BMS systems, or locomotive/rail applications
• Bonus: Have built EN 50155 compliant devices, or familiarity with the standard.
