About the Role
The UK water sector is entering a period of unprecedented investment and transformation. Egis is expanding rapidly in the UK, backed by a global team of more than 23,500 experts across 70+ countries, designing and delivering intelligent, sustainable infrastructure to address climate challenges and strengthen community resilience. As part of our fast-growing UK Water team, you will join an agile environment where progression is quick, visibility is high, and your impact is immediate.

We are building a high-performing Process Engineering team to help shape the next chapter of water and wastewater programmes in the UK municipal and industrial sectors. Working within a collaborative, multidisciplinary environment, you will contribute to technically robust, sustainable, and innovative treatment solutions across nationally significant projects.

This is a rare opportunity to join at a key stage of our UK growth journey, helping to establish, shape, and expand a process engineering capability built on Egis’ global infrastructure expertise and long-term commitment to the sector.
