(IT/OT & SCADA COMMUNICATION INFRASTRUCTURE)
SUMMARY- IT/OT & SCADA COMMUNICATION INFRASTRUCTURE
The Network Systems Engineer is responsible for the design, configuration, testing, commissioning, and ongoing support of communication networks and networked devices that enable both Information Technology (IT) and Operational Technology (OT) systems. This role supports mission‑critical infrastructure such as distributed telemetry networks, SCADA systems, industrial control systems (ICS), and enterprise networks.
The engineer applies application‑level engineering judgment to translate functional and operational requirements into secure, reliable, and high‑availability communication and computing solutions. This role supports geographically distributed assets including plants, substations, control centers, and remote field installations, and collaborates closely with engineering, operations, application programmers, cybersecurity experts, and field teams.
KEY RESPONSIBILITIES- Network & Telemetry Engineering
- Design, integrate, configure, test, and support industrial communication networks and telemetry systems supporting SCADA and OT environments
- Perform application engineering to ensure network solutions meet customer objectives, system requirements, performance targets, and environmental constraints
- Evaluate existing network and telemetry systems and recommend improvements or upgrades
- Integrate, configure, and support industrial network devices including:
- Core and edge Ethernet switches
- Layer 3 switches and routers
- Firewalls, VPN appliances, and secure gateways
- Radio transceivers, cellular modems, and telemetry devices
- Configure and maintain network equipment in accordance with internal standards and cybersecurity best practices
- Assist with equipment deployment, on‑site configuration, and system troubleshooting
- Design industrial network topologies supporting reliability, redundancy, and deterministic communications
- Configure Layer 3 switches to support:
- VLAN creation and segmentation
- Inter‑VLAN routing
- Traffic isolation and access controls
- Develop IP addressing schemes, subnetting strategies, and routing designs appropriate for OT environments
- Support secure IT/OT separation using firewalls, DMZ architectures, and VPN technologies
- Physical Computing Infrastructure Integration
- Ensure proper integration server rack infrastructure and network interconnection interfaces in accordance with project design, best practices, and engineering, safety, and documentation standards
- Establish physical and logical network interconnections between devices to support core network infrastructure and defined topologies
- Ensure rack and infrastructure builds align with cybersecurity, maintainability, and operational best practices
- Virtualized Computing & SCADA Support Systems
- Configure and assist with deployment of computer hardware including terminals, engineering workstations, and servers used to support SCADA and OT environments
- Install and configure hypervisors on physical hardware to enable secure, virtualized system implementations
- Deploy and configure operating systems in preparation for use by internal teams, including Automation Engineers responsible for SCADA application development and programming
- Collaborate with automation, controls, and IT teams to support development, testing, and deployment of SCADA applications
- Wireless, RF & Telemetry Communications
- Engineer and support distributed telemetry networks using wired and wireless communication paths
- Coordinate and perform radio feasibility studies and radio frequency (RF) assessments
- Analyze signal strength, interference, latency, throughput, and reliability issues
- Apply RF propagation principles to evaluate coverage, interference, throughput, and reliability
- Prepare formal documentation and reports for radio studies and system assessments
- Apply radio frequency (RF) propagation principles to design and troubleshoot wireless links
- Coordinate licensed and…
