Job description

Who We Are:

At Voltify, we are building the next generation of rail - battery locomotives that fast charge autonomously and dynamically through a dedicated self-sustained microgrid network.

We are bringing back the power to the industry and eliminating the dependency on fossil fuels.

Lowering the rail industries main expense - energy - by more than 20%.

This is over $3B yearly just in North America.

We are already working with some of the largest global rail companies with over $50M in contingent orders.

We have raised over $30M from top tier funds and strategics and rapidly growing.

Our founding team has a proven track record in building billion $ public companies in renewable energy and infrastructure.

About The Role:

We're looking for a Firmware/Embedded Software Engineer to write and test software for our battery electric locomotive control systems. You'll work on everything from low-level embedded firmware to industrial HMI interfaces, collaborating closely with electrical and mechanical teams to bring our locomotive to life.

We want a driven, fast-paced self-learner who can move between embedded C/C++ development, Linux system configuration, and high-level HMI design while maintaining rigorous safety standards.

We offer a competitive salary, comprehensive benefits, and the opportunity to build the software backbone of the future of rail technology.

What You'll Do:

  • Write and test embedded software and firmware for locomotive system controls (C/C++, Python)
  • Design and implement industrial HMI interfaces using HTML or GUI programming frameworks
  • Configure and maintain Linux systems, including BASH scripting and network configuration
  • Implement robust communication stacks for Ethernet, CAN Bus, I2C, and SPI protocols
  • Develop control algorithms for high-voltage systems including BMS and power routing
  • Create and maintain software architecture documentation and technical specifications
  • Implement simple signal filtering and data processing algorithms
  • Develop network APIs and integrate with SCADA systems and MQTT protocols
  • Design software for safety-critical systems with proper validation and verification
  • Collaborate with electrical engineers on embedded controller integration
  • Support system testing and validation in lab and field environments

What We're Looking For:

  • 3+ years of embedded software/firmware development experience (automotive, marine, industrial, or rail preferred)
  • Strong proficiency in C, C++, and Python
  • Experience with Linux system administration, configuration, and shell scripting
  • Hands-on experience with communication protocols: CAN Bus, Ethernet, I2C, SPI
  • Knowledge of high-voltage system control (BMS, power routing, contactor control)
  • Experience designing industrial HMI interfaces (web-based or native GUI)
  • Understanding of software architecture and documentation practices
  • Familiarity with safety-critical software development principles
  • Nice to have: STM32 microcontroller experience
  • Nice to have: MATLAB/Simulink experience for model-based design
  • Nice to have: Experience with SCADA systems, MQTT, or industrial IoT protocols
  • Ability to thrive in fast-paced, high-pressure startup environments
  • Proactive problem-solver who takes ownership from concept to deployment
  • Passion for clean energy and sustainable transportation
  • Bonus: Experience with battery management systems or electric vehicle controls
  • Bonus 2: Loves trains
