National Grid is hiring a Senior Engineer for our DC&I Engineering department in Northboro, MA

As a Senior Engineer in DC&I, you will serve as a technical leader supporting National Grid's ESMPaligned Grid Modernization initiatives, with a primary focus on operational technology (OT) network engineering and communications for distribution field devices outside of the substation. This role enables the reliable, safe, and secure operation of distribution automation systems such as DERMS, FLISR, Volt/VAR Optimization (VVO), and other intelligent grid applications deployed across the distribution network.

In this position, you will own and influence OT communications architecture and network design for gridedge devices including reclosers, voltage regulators, switches, RTUs, and other distribution automation assets. As a senior engineer, you will act as a technical subjectmatter expert and escalation point, working handson with IPbased networking, field and widearea communications, and cybersecurity controls. You will collaborate closely with DC&I peers, SCADA/ADMS, IT, telecom, and cybersecurity teams to deliver scalable, resilient, and secure communications solutions, while helping guide technical standards and mentor engineers supporting distribution automation.

• Serve as a technical lead for OT network engineering and communications architecture supporting distribution field devices deployed outside of substations, including reclosers, voltage regulators, switches, RTUs, and other gridedge automation assets.
• Design, implement, and support IPbased network architectures enabling reliable and secure communications between distribution field devices, control centers, and enterprise systems.
• Own and influence field area and widearea communications solutions leveraging technologies such as private LTE, carrier Ethernet, MPLS, and SDWAN to support realtime distribution automation and control.
• Support the deployment, integration, and operation of distribution automation and grid modernization applications including DERMS, FLISR, Volt/VAR Optimization (VVO), and Conservation Voltage Reduction (CVR).
• Apply deep working knowledge of TCP/IP networking (routing, switching, VLANs, subnetting, segmentation) to ensure resilient, scalable, and observable OT communications.
• Collaborate with IT, telecom, and cybersecurity teams to design and implement secure OT network solutions, including firewalls, access control, segmentation, monitoring, and secure remote access, aligned with industry and regulatory requirements.
• Act as a technical subjectmatter expert and escalation point for complex communications and networking issues impacting SCADA, ADMS, DERMS, and other distribution automation systems across lab, pilot, and production environments.
• Evaluate emerging technologies, participate in equipment specification and selection, and lead validation, testing, and integration of new distribution communications and automation solutions.
• Contribute to the development and maintenance of technical standards, design patterns, and best practices for distribution OT networking and communications.
• Mentor and provide technical guidance to engineers and project teams, supporting consistent and highquality implementation of distribution automation solutions.
• Support project planning and execution to deliver grid modernization capabilities aligned with ESMP vision, operational needs, and safety priorities.

• Bachelor's degree or higher in Electrical Engineering, or a related technical discipline from an accredited institution is required.
• 6+ years of relevant experience, or equivalent demonstrated expertise, supporting distribution automation, OT networking, or control system communications in utility or missioncritical environments preferred.
• Strong handson experience with IPbased networking in OT environments, including routing, switching, VLANs, subnetting, segmentation, and network troubleshooting preferred.
• Working knowledge of distribution automation and control systems such as SCADA, ADMS, DERMS, FLISR, VVO, or similar intelligent grid applications preferred.
• Understanding of cybersecurity principles for OT and industrial control systems, including defenseindepth, network segmentation, access control, monitoring, and secure remote access preferred.
• Ability to translate operational and engineering requirements into robust network and communications designs, and to interpret network diagrams and interface specifications preferred.
• Strong communication skills, with the ability to clearly explain technical concepts to engineering peers, operations personnel, and leadership.
• Willingness to work flexible hours and travel as needed.
• A valid driver's license is required.

The DC&I Engineering team at National Grid drives the development and implementation of advanced grid modernization technologies. Our core mission is to equip the Distribution and Transmission Control Centers with innovative solutions that enhance efficiency, reliability, and above all-safety of grid operations. As Distributed Energy Resources (DERs) continue to expand across the power system, we apply our deep expertise to advance grid-edge technologies that enable seamless integration of these assets into our Distributed Energy Resource Management System (DERMS).
