At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

The water sector in Ireland is undergoing a major transformation. Unprecedented investment and technological advancement are creating a once-in-a-generation opportunity to redefine water and wastewater infrastructure.

We’re proud to be at the forefront of this transformation, partnering with large companies across Ireland to deliver water and wastewater services and better manage water related risks. From strategic planning and flood management at various stages of the project lifecycle - from concept through to commissioning, we bring together exceptional talent and expertise to deliver success.

We’ve secured multiple long-term frameworks and programmes with leading clients across Ireland, including Uisce Éireann (Irish Water), Northern Ireland Water, and the Northern Ireland Department for Infrastructure (DfI). These major initiatives span water, wastewater, flood management, and environmental protection—delivering critical infrastructure that makes a real difference to communities.

To support our expanding portfolio and future growth ambitions in Ireland, we are looking for Senior Water Networks Engineers/Modellers to join and strengthen our established Water team, based across our Dublin, Cork and Belfast offices.

You will have the opportunity to lead a diverse range of projects, including water trading, capital design, water quality modelling, network design, zonal studies, leakage optimisation, and model maintenance. You will apply industry‑leading solutions and be encouraged to introduce innovative approaches. In addition, you will support and mentor local teams while contributing to the continued growth of our Irish water business.

This is your chance to influence the future of water. Join us and be part of the transformation. Together, we will make it happen.
