Principal Engineer - Water D&B

Your Impact

Shape the Future of Water. Lead What Matters.

The UK water sector is changing faster than ever before. With unprecedented investment and sector‑wide reform underway, this is a once‑in‑a‑generation moment to leave your mark on critical national infrastructure.

If you’re a Civil Engineer/Senior Civil Engineer or a Principal Civil Engineer ready to lead, influence and shape complex water and wastewater projects, this is your opportunity to step into a role where your expertise truly counts.

You’ll be at the heart of transformational water and wastewater programmes, setting technical direction, mentoring future talent and influencing how vital assets are designed, built and operated for decades to come.

Your work will:

• Safeguard communities and the environment through safe, compliant and buildable designs
• Drive low‑carbon, sustainable solutions using modern methods of construction and digital engineering
• Shape smarter, safer infrastructure by embedding constructability, operability and CDM best practice
• Leave a lasting legacy across some of the UK’s most high‑profile water frameworks

We’re proud to be at the forefront of transformation in the UK water sector, partnering with major water companies including United Utilities, Northumbrian Water, Thames Water, Severn Trent Water and Anglian Water.
