• Support inter-trip schemes, GOOSE messaging, automation protocols, and protection interface signals.
• Validate control logic changes in coordination with the Senior HV Protection & Control Engineer.

OT Network & Cybersecurity:

• Maintain secure OT networks including firewalls, VLANs, DMZs, routers, switches, and time-synchronisation systems (GPS/NTP/PTP).
• Support NIS/NIS2, IEC 62443, and CNI cyber compliance through patching, vulnerability assessments, and incident response.
• Monitor OT network health, cyber logs, and communication performance.

Data Availability & Telecoms:

• Ensure high telemetry availability for Operations, outage planning, and engineering analytics.
• Manage telecoms: microwave links, fibre networks, radios, and GPS-based timing infrastructure.
• Support historian data pipelines for condition monitoring and performance analysis.
• Support the Senior HV Protection & Control Engineer during protection-related events and system disturbances.
• Contribute to technical investigations and post-fault reports requiring digital/telemetry insight.

Future Capability Development:

• Support future SCADA/OT projects in offshore wind, interconnectors, and digital engineering consultancy.
• Align with our HV Remote Control Centre to enable secure, resilient remote SCADA monitoring - advising on enhanced cyber-secure connectivity mechanisms and supporting the delivery of the organisation's wider digital and OT security objectives.

Who are we looking for?

You will have strong system diagnostic and problem-solving skills and rigorous configuration control and documentation discipline.
