OT Network & Site Infrastructure Engineer

About This Role

As an OT Network & Site Infrastructure Engineer on Intersect's Corporate IT team, you'll build and secure the physical and logical communication backbones that connect our utility-scale clean energy facilities to corporate systems and the grid. You'll operate as the primary on-site technical authority for greenfield infrastructure deployments, establishing resilient IT/OT network segmentation, managing enterprise firewalls, and integrating industrial detection tools across our solar, storage, and generation assets. Partnering closely with Engineering, SCADA, and Operations teams, you'll ensure continuous, secure telemetry and high operational uptime across distributed sites. This role is planned to start on August 3, 2026.

Location: Dallas, Houston, Abilene, Pampa, or Amarillo

Team Overview

This team plays a critical role in advancing Intersect's mission to accelerate the clean energy transition. The Corporate IT and OT Infrastructure team designs, secures, and maintains the digital tissue connecting remote field assets, control systems, and enterprise tools. Joining this team means stepping into a high-ownership environment with a lean hierarchy, driving greenfield network implementations from scratch, and growing alongside cross-functional experts dedicated to operational excellence.

What You'll Do

Architect and Implement Greenfield OT Networks

• Deploy and configure industrial switches, Palo Alto firewalls, and routing infrastructure across new clean energy site locations.

• Establish robust IT/OT network segmentation architectures adhering to industry best practices and NERC CIP controls.

Maintain Field Security and Remote Access Platforms

• Administer secure remote access solutions including Site-to-Site VPNs, Zero Trust Network Access (ZTNA), and dedicated jump servers.

• Integrate and manage OT Network Intrusion Detection Systems (Nozomi, Claroty, Dragos) alongside CrowdStrike endpoint protection across remote locations.

Troubleshoot Communication Networks and SCADA Connectivity

• Diagnose and resolve complex industrial network issues affecting SCADA Ignition connectivity, RTU telemetry, and field sensors.

• Perform site-level network performance optimization, bandwidth management, and failover validation to maintain high asset availability.

Provide On-Site Technical Leadership

• Serve as the primary technical authority on-site during commissioning and integration, directing vendor activities and physical network handoffs.

• Collaborate cross-functionally with IT, SCADA, and Field Operations to establish standardized network configuration, documentation, and monitoring procedures.

What You'll Bring

• Bachelor's degree in Network Engineering, Information Technology, Computer Science, or equivalent industrial field experience.

• 5+ years of network and infrastructure engineering experience, with explicit focus on OT, industrial control systems, or utility environments.

• Hands-on expertise administering enterprise and industrial network hardware (Palo Alto, Cisco, Hirschmann) and implementing IT/OT segmentation standards (Purdue model).

• Proven track record managing remote access architectures (S2S VPN, ZTNA, jump servers) and troubleshooting SCADA/Ignition network communication layer issues.

• Direct experience deploying OT threat detection platforms (Nozomi, Claroty, or Dragos) and endpoint detection (CrowdStrike).

• Self-directed operational mindset, comfortable acting as the primary technical authority on project sites with up to 50% travel.

• Strong collaborative instinct and alignment with Intersect's core values of Equity, Humility, Authenticity, Long-run Value, and People Come First.
