Grid Stor is looking for a Senior Network Engineer who will be responsible for making critical networking decisions and managing all network-related activities for Utility Scale Battery Energy Storage Systems (BESS). This role will drive network infrastructure from late‑stage development through construction and commissioning, leading into operations, both within budget and on schedule. This position will report to the SCADA & Controls Manager and will be based in Portland, OR, with a hybrid work schedule.

• Own and execute network engineering for projects in late-stage development through construction stage, including leading the design and configuration of LANs/WANs, procuring networking hardware such as switches, routers, and firewalls, managing scope, risks, network schedules, budgets, and coordinating with major stakeholders and decision makers to ensure seamless integration with BESS control systems.
• Maintain network systems for operating projects, including monitoring performance metrics, applying security patches and firmware updates, conducting regular audits for reliability and cybersecurity, optimizing bandwidth and latency for real-time data transmission, and ensuring compliance with operational standards such as NERC/CIP and IEEE guidelines.
• Deploy network systems related to utility scale BESS for in-house EMS, including installing and configuring switches, routers, firewalls, cellular devices, and fiber optic infrastructure; integrate with SCADA/EMS protocols like Modbus, DNP3, and IEC 61850; and troubleshoot and maintain existing EMS for operating projects by resolving connectivity issues between BMS, PCS, protection relays, and remote monitoring platforms.
• Interface with EPC, major equipment suppliers, consultants, independent engineers, and other cross-functional teams, acting as the main technical point of contact for networking matters by coordinating design reviews, providing technical guidance on network requirements, reviewing deliverables, and facilitating resolution of integration challenges during commissioning and operations.
• Act as the subject matter expert in utility scale BESS networking, with expertise in one or more of the following areas and ability to quickly pick up other areas along with additional support (through consultants or in-house expertise):
  • Network design and integration, including modeling Balance of Plant network architecture, and ensuring grid-tied compatibility with inverters and control systems.
  • Firewall and VPN configuration, including setting up secure remote access, intrusion detection systems, and encryption for OT environments.
  • Switch and fiber optic logic implementation, including VLAN segmentation, routing protocols, and fiber optic standards for high-reliability connections.
  • AWS integration and management, including cloud-based monitoring, virtual servers, and hybrid on-prem/cloud networking for data acquisition and analytics.
  • SCADA/EMS system networking for utility scale BESS, including protocol configuration for real-time control, data historian integration, and fault-tolerant redundancy.
• Review and ensure compliance to Interconnection Agreements, Interconnection Handbooks, all applicable codes and standards including relevant networking protocols (e.g., TCP/IP, DNP3, Modbus), security standards (e.g.,…
