The OT Network & I&C Specialist is responsible for maintaining the reliability, performance, and security of operational technology (OT) networks and associated SCADA systems across GRS’s utility-scale solar portfolio. This role forms part of the central I&C team and supports the operation and maintenance phase of assets. The position ensures the integrity of communication systems linking field devices (inverters, trackers, meteorological stations) to plant-level and central SCADA systems. The role interfaces closely with site based I&C technicians, engineering teams, OEM vendors, and the corporate IT function to ensure:
- Implementation of appropriate OT cyber security controls
Key Duties and Responsibilities
- Maintain, configure, and troubleshoot plant-level industrial communication networks, including managed switches and routers.
- Monitor network performance and availability to ensure reliable real-time telemetry across the plant.
- Implement and maintain Layer 2/Layer 3 configurations.
- Support standardisation of network design and configuration across the portfolio.
- Support diagnosis and resolution of communication faults between OT network infrastructure and control systems (PLCs, RTUs, SCADA interfaces).
- Work collaboratively with site I&C personnel during fault-finding and restoration activities.
- Commissioning activities for plant expansions or retrofits.
- Review and validate “as-built” network documentation to ensure compliance with GRS standards.
- Act as technical liaison with OEMs and vendors for equipment issues, firmware updates, warranty claims, and OT Cyber Security Implementation.
- Support the implementation of OT cyber security requirements in alignment with internal standards.
