Lead Controls Engineer

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.

• →Design, develop, deploy, and maintain PLC software for microgrid control management across a variety of platforms — both hardware PLCs and soft-PLCs (PC-based / runtime controllers).
• →Implement control logic in CODESYS and in proprietary / vendor-specific environments — for example Siemens TIA Portal (SCL/STL), Rockwell Allen-Bradley Studio 5000 / RSLogix, Beckhoff TwinCAT, B&R Automation Studio, Schneider EcoStruxure / Unity, Mitsubishi GX Works, or Omron Sysmac.
• →Write robust, maintainable code using the IEC 61131-3 languages (Structured Text, Ladder, Function Block Diagram, Sequential Function Chart) as each platform and task demands.
• →Architect and implement control for complex microgrid systems — managing solar inverters, battery energy storage systems (BESS), grid-tie interconnections, and EV/locomotive chargers, including islanding/reconnection and protection coordination.
• →Integrate diverse industrial hardware using protocols such as Modbus TCP/RTU, OPC-UA, DNP3, and CANbus.
• →Implement and harden the bi-directional Cloud ↔ Edge communication pipeline (e.g. via MQTT), ensuring data integrity and gracefully handling connectivity edge cases.
• →Travel frequently to our deployment sites for on-site commissioning, integration testing, and troubleshooting — this is a meaningful part of the job, not an occasional add-on.
• →Set engineering standards, conduct code reviews, define MVPs, and make architectural decisions that balance speed with reliability — laying the groundwork to build and lead the U.S. controls team.

• 6+ years of hands-on PLC software development, with proven experience implementing multiple types of PLCs — both hardware PLCs and soft-PLCs.
• Strong command at least two PLC environments (e.g. Codesys, Siemens, Rockwell, Beckhoff, B&R, Schneider, Mitsubishi, Omron) — and the ability to ramp quickly on any platform we throw at you.
• Fluency in the IEC 61131-3 languages (Structured Text, Ladder, FBD, SFC) and sound judgment about when to use each.
• Fluency in industrial communication protocols: Modbus TCP/RTU, OPC-UA, DNP3, or CANbus.
• A proven track record integrating software with physical hardware. You are comfortable debugging issues where the "bug" might be a loose wire, a protocol mismatch, or a misconfigured register map.
• Good proficiency in Python. Beyond PLC programming, you build standalone services, data pipelines, and automation tools. We treat this as a signal — the engineers who thrive here move fluidly across the whole stack instead of staying boxed into one layer.
• Range. You can hold the whole system architecture in your head and also obsess over the smallest detail. You adapt fast when requirements change and stay effective when the task is something you've never done before.
• Extreme ownership, strong research and learning ability, and excellent critical-thinking and problem-solving skills.
• Willingness to travel extensively to our sites across the U.S. (and occasionally beyond).
• The ambition and interpersonal skills to grow into a leadership role managing the U.S. team.
