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, Mod Bus, 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 development

    Integrate 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, Mod Bus, I2C, SPI
  • Understanding of embedded systems and controller integration - we use STM
    32
  • 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.
