Design Engineer – CNG & Biogas

Gas Networks Ireland operates and maintains Ireland’s €2.7bn, 14,664km national gas network, which is considered one of the safest and most modern renewables-ready gas networks in the world.

Over 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, including 40% of all heating and almost 50% of the country’s electricity generation.

By working to replace natural gas with renewable gases, such as biomethane and green hydrogen, and complementing intermittent renewable electricity, Gas Networks Ireland is supporting Ireland’s journey to a cleaner energy future.

Gas Networks Ireland is now seeking to appoint a Design Engineer to work primarily on the design of renewable natural gas (RNG) injection facilities. However, flexibility and the willingness to work on other projects, e.g., CNG/RNG automotive refuelling facilities, as business needs dictate will be necessary.
