Remote working with visits to sites as required.

The Role: As a Senior SCADA & OT Engineer within the Asset Integrity Management (AIM) Team and reporting directly to the Global Head of Engineering, you will act as the technical authority for SCADA systems, control systems, operational technology (OT), telemetry, and operational cybersecurity across OFTO assets. The role ensures secure, reliable, and compliant digital control environments supporting offshore and onshore HV operations. You will provide system ownership, configuration governance, cyber assurance, and expert fault response across the asset lifecycle.

Key Duties and Responsibilities:

• Maintain and optimise SCADA systems, RTUs, PLCs, bay controllers, relays, I/O modules, HMIs, and others.
• Ensure accurate signalling for alarms, events, analogue values, breaker states, and system statuses.
• Manage historian systems (PI, InfluxDB, Genesys, etc.), ensuring data availability and integrity.
• Maintain configuration records, backups, firmware, and version control.
• LCM of SCADA systems, including design, deployment, maintenance, upgrades, and decommissioning, ensuring system reliability, cybersecurity compliance, and integration with control and telemetry systems.
• Manage remote SCADA logins for Senior Authorised Persons, Asset managers, and other responsible persons.
• Compliance with applicable standards - IEC 62443, NIS/NIS2, IEC 61850, ISO 27001, ISO 9001/14001/45001, ISO 55000 asset management, and GDPR.

Control & Automation:

• Implement logic updates, mimic revisions, setpoint changes, and control sequences.
• 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. Effective communication across Operations, Engineering, and Cyber teams is essential. The ability to work proactively during faults or critical events and have a structured and methodical engineering approach is required. Promote safe work practices in control rooms and substations, maintain accurate configuration control and change records. Lead by example on life-saving rules and safe systems of work. Produce or contribute to the production of clear risk assessments, method statements, and technical reports for SCADA / OT related tasks.

Skills and Experience:

• Degree in Automation, Control Systems, Electrical Engineering, or IT/OT Engineering.
• Experience with SCADA systems, PLCs/RTUs, historian platforms, and OT networks.
• Understanding of OT cybersecurity frameworks (IEC 62443, NIS/NIS2).
• Certifications preferred: IEC 62443 practitioner or equivalent; ISO 27001 awareness.
• Experience in transmission, offshore wind, OFTO, or industrial control environments.
• Familiarity with telecoms systems (microwave, fibre, radios, GPS clocks).
• Proven ability to operate as a senior technical authority under operational pressure.
• GWO certifications and Offshore Medical (or willingness to obtain) for offshore access (if desired).

Competitive benefits tailored to the division. Opportunities for career growth and visibility across the organisation. A supportive, inclusive culture that values your ideas and contributions. Work that truly makes a difference in safety, innovation, and global capability.
