Egis is expanding rapidly in the UK, backed by a global team of more than 23,500 experts across 70+ countries. We design and deliver 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.

The UK water sector is entering a period of unprecedented investment and transformation. As Egis accelerates the growth of its Water Business in the UK, we are building a high-performing Civil Engineering team to help shape this next chapter.

We are inviting applicants who want to play a meaningful role in delivering major water and wastewater programmes. 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 civil engineering capability built on Egis’ global infrastructure expertise and long‑term commitment to the sector.
