Job description

Senior Design Engineer Mechanical – Compressors (x2)

Gas Networks Ireland operates and maintains Ireland’s €3bn, 14,758km national gas network, which is considered one of the safest and most modern renewables-ready gas networks in the world.

Almost 720,000 Irish homes and businesses trust Ireland’s gas network to provide efficient and reliable energy to meet their heating, cooking, manufacturing and transport needs.

The gas network is the cornerstone of Ireland’s energy system, securely supplying more than 30% of Ireland’s total energy and over 40% of the country’s electricity generation.

Gas Networks Ireland is aiming to deliver a repurposed, resized and fully decarbonised gas network by 2045. Its “Pathway to a Net Zero Carbon Network” envisions transforming the existing gas network into two separate systems carrying 100% renewable gas, one dedicated to biomethane and the other to green hydrogen, with the potential to carry approximately 30% biomethane and 70% green hydrogen, as well as offering significant long term energy export opportunities.

Gas Networks Ireland is an organisation with a very strong legacy and a culture founded on pride in our purpose, to keep Irelands energy moving, and commitment to our vision, to be at the heart of Irelands energy future. Our organisational values demonstrate what is important across the organisation including building on our experience across our organisation to build towards our sustainable future, doing what's right for each other and for the people and communities that we serve and finally energised for the change of our future towards a renewable energy landscape.
