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
