Network Architect -ADMS / SCADA / OMS

· Develop detailed, accurate network and system architecture diagrams for ADMS components and integrations (OMS, SCADA, DMS, DERMS, GIS). · Document system processes, network flows, and interface points aligned with enterprise architecture standards. · Support design and optimization of ADMS capabilities within the broader enterprise architecture.

1. Firewall Rule Definition & Security Design · Draft and verify firewall rules and communication paths required for ADMS, ensuring cybersecurity and real-time performance. · Define architecture standards and secured interfaces for ADMS components including OMS, SCADA, DMS, DERMS, and supporting systems.

2. IP Addressing, Hostnames & Network Segmentation Documentation · Document IP schemes, hostnames, LAN/VLAN segments, and routing requirements for all ADMS hardware and integrated platforms. · Maintain comprehensive documentation supporting ADMS hardware upgrades, data integrity, and cloud/enterprise integration.

3. Network Failure-Mode Analysis & Testing · Identify technical risks, potential failure modes, and mitigation strategies across the ADMS network architecture. · Support or lead testing of failover scenarios, redundancy models, segmentation behaviors, and real-time performance validation. · Ensure network design supports reliability, outage management, switching operations, and real-time situational awareness. Collaboration & Communication · Work closely with Grid Operations, OT teams, SCADA engineers, cybersecurity, and vendors to ensure alignment of network designs with ADMS operational needs. · Communicate complex technical subjects clearly to technical and business stakeholders.

· Proven experience in enterprise network architecture, including LAN/WAN, routing, switching, firewall design, segmentation, redundancy, and security zoning. · Experience designing networks for real-time systems or mission-critical operational technologies. · Ability to document architecture clearly and proactively identify technical risks.

Highly Desirable Experience (ADMS / SCADA / OMS) · Familiarity with ADMS systems, including SCADA, OMS, DMS, DERMS, and GIS integration. · Experience supporting large-scale ADMS modernization, hardware upgrade, or OT network transformation programs. · Knowledge of secure OT/IT boundary architectures and real-time operational technology requirements. · Understanding of telemetry flows, control center operations, and connectivity requirements for grid modernization initiatives.
