ON.energy is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers.
The EMS team is looking for a SCADA Engineer to own the core configuration of our SCADA platform in Ignition, primarily tag structures, UDT setup, and communication with field devices. This person will support the HMI team and the controls team by developing tools that speed up SCADA configuration, deployment, and ongoing support of our current and evolving SCADA solution across battery energy storage systems (BESS) and grid connected assets.
KEY RESPONSIBILITIES
• Configure and maintain SCADA tags, UDTs (User Defined Types), and device connections in Ignition, ensuring a consistent and scalable foundation across sites.
• Design and maintain MQTT based communication for SCADA, including broker configuration, topic structure, and integration with Ignition.




• Integrate SCADA systems with PLCs and other field devices across BESS and grid connected inverter topologies, using protocols such as MQTT, Modbus TCP/RTU, OPC UA, and DNP3.
• Build and maintain tools that support the HMI team, such as automated UDT and tag generation, configuration templates, and data validation utilities.
• Build and maintain tools that support the controls team, such as scripts for point checkout, configuration comparison, and deployment automation.
• Identify and implement improvements to the efficiency, performance, and reliability of the current SCADA configuration and deployment process as it continues to develop and scale.
• Troubleshoot SCADA and communication issues in both development and live production environments, including field support as needed.
• Support commissioning activities, including point to point checkout, alarm validation, and system testing.
• Document SCADA confi
