ON.energyis 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.
Location: Site based in United States (Amarillo, TX initially), 90% site based travel
Compensation: Hourly with overtime eligibility and per diem
Position Overview
The Field Network Technician is responsible for deploying, configuring, and maintaining field-level communications infrastructure for Battery Energy Storage Systems located within Data Centers. This role is highly technical and hands-on, requiring deep knowledge of networking, industrial protocols, controls, and OT/SCADA systems. The technician will support commissioning, troubleshooting, and secure connectivity for distributed site networks across utility-scale renewable energy and energy-storage deployments.
This is a highly hands on, field based role focused on OT network deployment, commissioning, troubleshooting, and onsite implementation within active energy and industrial environments, best suited for candidates who enjoy travel and practical field execution over enterprise IT administration or network architecture.
Network Deployment & Configuration
• Collaborate with control systems, SCADA, EMS, IT, cybersecurity, and commissioning teams to ensure complete, secure, and reliable connectivity for field assets.
• Specify, deploy, and configure routing, switching, wireless, and security hardware (Cisco, Fortinet, Ubiquiti, Cradlepoint, etc.).
• Implement segmented OT networks including VLAN management, VPN configuration, firewall policies, and redundant network pathways.
• Integrate and support industrial communication protocols such as Modbus TCP, Modbus RTU, DNP3, MQTT, OPC-UA, and vendor-specific interfaces.
• Support commissioning of BESS, SCADA servers, RTUs/PLCs, and EMS platforms.
• Establish communication between field devices, HMIs, sensors, relays, networking gear, and remote operations centers.
• Validate I/O, device polling, SCADA mappings, and command pathways between site-level control systems.
• Diagnose issues across hardware, software, and protocol layers in active construction and live plant environments.
• Analyze packet flows, latency, port conflicts, routing loops, and device misconfigurations using industry tools (Wireshark, SolarWinds, etc.).
• Provide remote access and secure tunneling support for engineering, OEMs, and operations teams.
Cybersecurity & Compliance
• Implement cybersecurity controls aligned with NERC CIP, NIST 800-82, ISO/IEC
• Monitor, log, and mitigate vulnerabilities in OT network infrastructure.
Documentation & Quality
• Maintain as-built network diagrams, IP addressing plans, fiber/copper maps, and equipment inventories.
• Update network and control architecture drawings in coordination with SCADA/Engineering teams.
• Follow strict change-management and version-control processes.
Requirements:
• 2+ years of hands-on network engineering experience in project-based, industrial, utility, or field-deployment environments.
• Proven experience in IT, commissioning, or deploying project networks (not only operations or enterprise IT support).
• Strong understanding of networking fundamentals and protocols: TCP/IP, BGP, OSPF, STP, VLANs, VPNs, NAT, DHCP, DNS.
• Experience working with OT, SCADA, industrial controls, or power-system environments.
• Ability to read, interpret, and create network, single-line, and control architecture drawings.
• Strong communication skills with the ability to interface across technical and non-technical teams.
• Willingness to travel up to 80% for commissioning, site integration, FAT/SAT, and network deployment.
