You will own site-level architectures, M2M integrations, and secure connectivity between sites, utilities, and cloud platforms.

The role requires 5+ years in utility communications/OT, with strong knowledge of Modbus TCP/IP, DNP3, IEC 61850, OPC UA, and OT cybersecurity.

Qualifications

Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related discipline, or equivalent relevant work experience.
At least 5 years of utility communications, industrial networking, OT systems, or energy management systems experience.
Strong understanding of firewalls and network security fundamentals.
Ability to debug network connections using tools such as Wireshark.
Extensive hands on experience with utility scale OT communication systems, including RTUs, PLCs, industrial gateways, and edge/data collection devices.
Strong experience with industrial and utility protocols such as Modbus TCP/IP, DNP3, IEC 61850 (preferred), and OPC UA.
Strong understanding of OT cybersecurity principles, including defense in depth architectures, secure remote access/VPNs, and network segmentation and monitoring.
Experience implementing secure communication paths between OT and IT systems.
Comfort working with field data, diagnostics, and system telemetry.
Proficiency in English, both written and verbal.

Responsibilities

Lead integration of site controllers, inverters, and auxiliary equipment into a unified plant communications architecture.
Design and configure machine to machine (M2M) communications between site controllers, inverters, and plant level gateways and data concentrators.
Define and deploy end to end communication networks, including industrial Ethernet (fiber/copper), layered OT network segmentation, and integration of secure connectivity platforms, data collectors, and industrial gateways.
Design and support OT networks, including firewalls, routers, switches, VLANs and segmentation, and fiber optic networks.
Manage secure communication interfaces between sites and utilities, transmission operators, ISOs/RTOs, asset owners, and cloud based platforms.
Configure and validate protocols for wide area communications, including real time telemetry, dispatch and control signals, and event and disturbance reporting.
Design and implement multi layer cybersecurity architectures, including segmented network zones, secure data replication layers, and unidirectional gateways (data diodes) for critical assets.
Support compliance with NERC CIP standards, utility interconnection requirements, and internal cybersecurity frameworks.
Enable inverter monitoring, diagnostics, and fault detection through integration with cloud based dashboards.
Collaborate with O&M and engineering teams to troubleshoot issues and optimize system performance.
Maintain auditable data and communication structures to meet regulatory compliance requirements.
Other duties as assigned.
