This role is highly technical and hands-on, requiring deep knowledge of networking, industrial protocols, controls, and OT/SCADA systems. The technician will support commissioning, troubleshooting, and secure connectivity for distributed site networks across utility-scale renewable energy and energy-storage deployments. Network Deployment & Configuration * Collaborate with control systems, SCADA, EMS, IT, cybersecurity, and commissioning teams to ensure complete, secure, and reliable connectivity for field assets. * Specify, deploy, and configure routing, switching, wireless, and security hardware (Cisco, Fortinet, Ubiquiti, Cradlepoint, etc.). * Implement segmented OT networks including VLAN management, VPN configuration, firewall policies, and redundant network pathways. * Integrate and support industrial communication protocols such as Modbus TCP, Modbus RTU, DNP3, MQTT, OPC-UA, and vendor-specific interfaces. * Support commissioning of BESS, SCADA servers, RTUs/PLCs, and EMS platforms. * Establish communication between field devices, HMIs, sensors, relays, networking gear, and remote operations centers. * Validate I/O, device polling, SCADA mappings, and command pathways between site-level control systems. * Diagnose issues across hardware, software, and protocol layers in active construction and live plant environments. * Analyze packet flows, latency, port conflicts, routing loops, and device misconfigurations using industry tools (Wireshark, SolarWinds, etc.). * Provide remote access and secure tunneling support for engineering, OEMs, and operations teams. Cybersecurity & Compliance * Implement cybersecurity controls aligned with NERC CIP, NIST 800-82, ISO/IEC * Monitor, log, and mitigate vulnerabilities in OT network infrastructure. Documentation & Quality * Maintain as-built network diagrams, IP addressing plans, fiber/copper maps, and equipment inventories. * Update network and control architecture drawings in coordination with SCADA/Engineering teams. * Follow strict change-management and version-control processes. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [Optimizing Land-Based Fish Feeding with Node-RED](https://www.wearedevelopers.com/videos/2032-optimizing-land-based-fish-feeding-with-node-red) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [Enabling intelligent logistics automation: home-grown Industrial IoT platform at Austrian Post](https://www.wearedevelopers.com/videos/2018-enabling-intelligent-logistics-automation-home-grown-industrial-iot-platform-at-austrian-post) - [Turning Container security up to 11 with Capabilities](https://www.wearedevelopers.com/videos/718-turning-container-security-up-to-11-with-capabilities) ## Related Articles - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The Best Job Search Websites of 2025](https://www.wearedevelopers.com/magazine/368-the-best-job-search-websites-of-2025) - [Best Coding Boot Camps in Germany](https://www.wearedevelopers.com/magazine/237-best-coding-boot-camps-in-germany) - [Finding IT & Technology English-speaking Jobs in Germany ](https://www.wearedevelopers.com/magazine/446-finding-it-technology-english-speaking-jobs-in-germany)
