Network Architect - ADMS

Responsibilities

• Develop detailed network and system architecture diagrams supporting ADMS infrastructure and integrated utility platforms.
• Design and document secure communication paths, firewall rules, network segmentation, and OT security zoning.
• Define LAN/WAN architectures, VLAN segmentation, routing strategies, redundancy models, and high-availability network designs.
• Support architecture and integration of ADMS platforms including SCADA, OMS, DMS, DERMS, GIS, ICCP, Historian, and enterprise systems.
• Document IP addressing schemes, hostnames, routing requirements, interface mappings, and network topology standards.
• Analyze technical risks, operational dependencies, and mitigation strategies across OT and enterprise network environments.
• Support real-time operational technology requirements including telemetry flows, control center connectivity, and outage management systems.
• Collaborate with cybersecurity teams to implement secure OT/IT boundary architectures and compliance-aligned security controls.
• Perform network failure-mode analysis, resiliency planning, failover validation, and disaster recovery assessments.
• Support cloud integration, enterprise connectivity, and hybrid infrastructure initiatives where applicable.

Requirements

• 8+ years of experience in enterprise network architecture, OT infrastructure, or mission-critical operational technology environments.
• Strong experience with LAN/WAN networking, routing, switching, firewall design, VLAN segmentation, redundancy, and high-availability architectures.
• Experience designing or supporting operational technology (OT) networks and real-time systems.
• Hands-on experience with firewall technologies such as Palo Alto, Fortinet, Check Point, Cisco ASA, or equivalent platforms.
• Strong understanding of secure OT/IT boundary architectures, cybersecurity zoning, and network segmentation strategies.
• Experience supporting utility operational technologies including ADMS, SCADA, OMS, DMS, DERMS, GIS, ICCP, Historian, or related systems.
• Experience documenting network architectures, IP schemas, firewall rules, routing configurations, and technical infrastructure standards.
• Experience supporting network failover testing, redundancy validation, disaster recovery, and resiliency planning.
• Strong knowledge of enterprise networking protocols, routing technologies, and communication architectures.
• Experience with virtualization technologies such as VMware and enterprise infrastructure environments.
• Ability to analyze network traffic flows, telemetry communication paths, and operational dependencies.
• Strong troubleshooting, analytical, and technical problem-solving skills.
• Excellent communication and collaboration skills working with technical, operational, cybersecurity, and business stakeholders.
• Experience supporting electric utility, smart grid, energy, or critical infrastructure environments is highly preferred.
• Familiarity with control center operations, grid modernization programs, and utility operational workflows is highly desirable.
• Experience supporting ADMS modernization, hardware upgrade, or OT transformation programs is a strong plus.
