The Team
Ireland's offshore grid programme is a critical national infrastructure initiative supporting the country's 2030 renewable energy targets. EirGrid, as the designated Offshore Asset Owner (OAO), is responsible for ensuring the timely delivery, readiness, and operation of offshore transmission assets. The Offshore Programme Management Office (PMO) and Offshore Phase 1 Delivery Team play a central role in coordinating this transformation, ensuring robust governance, regulatory alignment, and delivery assurance across a multi-billion euro capital programme.
The Offshore Asset Readiness Programme (OARP) is responsible for ensuring EirGrid is operationally ready to assume ownership and management of offshore transmission assets. Cybersecurity is a critical capability within OARP, ensuring offshore infrastructure is designed, delivered, and handed over in compliance with statutory obligations, regulatory requirements, and industry best practice. The Offshore Cybersecurity Systems Specialist will play a key role in establishing and maturing EirGrid's offshore cybersecurity capability in support of critical national infrastructure.
The Opportunity
The Offshore Cybersecurity Systems Specialist will provide technical leadership and subject matter expertise across all cybersecurity aspects of Offshore Asset Readiness.
The role is responsible for supporting the establishment of offshore cybersecurity capabilities, ensuring regulatory compliance, reviewing cyber risk assessments, and embedding security and resilience by design throughout the delivery lifecycle.
The successful candidate will work across business, engineering, operational technology (OT), information technology (IT), and programme delivery teams to ensure offshore assets are delivered and transitioned into operation with effective cybersecurity controls and governance arrangements in place.
About you
Essential
- Degree or professional qualification in Cybersecurity, Computer Science, Computing, Electrical Engineering, Electronic Engineering, or equivalent.
- 10+ years cybersecurity experience within critical infrastructure, utility, industrial control system, or operational technology environments.

- Experience undertaking cybersecurity risk management and assurance activities in regulated environments.
- Demonstrated experience implementing security and resilience by design approaches.
- Experience converting technical cybersecurity requirements into project plans, deliverables, schedules, and business outcomes.

- Familiarity with OT protocols including IEC 61850, DNP3, OPC-UA and IEC-104.
- Experience with SIEM, SOC, detection and monitoring platforms such as Microsoft Sentinel, Splunk or QRadar.
- Experience in offshore wind, transmission system operations, or critical national infrastructure.
- Experience working with EPC contractors and major infrastructure delivery programmes.
- Knowledge of IT/OT convergence, segmentation, secure remote access, and cyber incident response.

About EirGrid Group
Company Overview
EirGrid Group
Dublin, Ireland
2006
Approximately 900 employees and revenue of $812.2 million in FY 2024 (source: rocketreach.co).
What They Do
EirGrid Group specializes in the operation and development of Ireland's national high-voltage electricity transmission grid. The company manages the flow of electricity from various generation sources, including a significant focus on renewable energy such as wind and solar farms, to end-users and the distribution network (source: countymeathchamber.ie). Their services encompass real-time grid operation, ensuring a safe and reliable electricity supply, and planning future infrastructure upgrades. EirGrid also operates the Single Electricity Market (SEM) across Ireland and Northern Ireland, facilitating efficient energy trading (source: eirgrid.ie). The company is committed to transitioning to a grid capable of handling 80% renewable electricity by 2030, currently achieving up to 65% renewables, and aims for a 95% operational capacity in the near future (source: rocketreach.co). Their target markets include the wholesale electricity market on the Irish island, serving both large industrial users and the ESB Networks distribution system.
Projects & Track Record
EirGrid Group has a robust portfolio of projects, including the East-West Interconnector (EWIC), a high-voltage subsea link completed in 2012 that connects Ireland's grid to Great Britain with a capacity of 500 MW (source: eirgrid.ie). The company is also jointly developing the Celtic Interconnector with RTE, a significant 2 GW subsea link from Ireland to France, which is currently under construction (source: siliconrepublic.com). Additionally, EirGrid manages the Greenlink Interconnector, another vital link between Great Britain and Ireland. The North-South Interconnector is another ongoing project, which involves a high-voltage line planned across counties Monaghan, Cavan, and Meath, with landowner engagements already underway (source: cbinsights.com). EirGrid is also leading offshore wind grid development, targeting an additional 10,000 MW of renewable capacity by 2030.
Recent Developments
In 2024, EirGrid Group reported maintaining its revenue at $812.2 million while continuing its grid transformation efforts (source: rocketreach.co). The company is advancing its five-year strategy aimed at achieving 70% renewable electricity by 2030, which includes significant updates on renewable connections, particularly in offshore wind (source: energyireland.ie). Progress on the Celtic Interconnector has been highlighted by CEO Mark Foley, emphasizing its importance for Ireland's energy security in light of Brexit (source: siliconrepublic.com). While there have been no major acquisitions or new funding rounds reported since 2020, the company continues to leverage its earlier SONI acquisition and EU funding to support ongoing projects (source: cbinsights.com). EirGrid's capability to operate the grid at 65% renewables is a significant milestone as they scale towards 95% by 2030.
