Site Engineer – Drive a Greener Future with the @One Alliance
Location: @one Sites
Who are we?
We’re the @one Alliance – a ground-breaking collaboration between Anglian Water and seven industry-leading partners: Balfour Beatty, Barhale, Binnies, MMB, MWH Treatment, Skanska and SWECO. Together, we deliver over half of Anglian Water’s capital investment programme.
As we prepare for AMP8, our most ambitious period yet, we’ll be delivering an even broader range of innovative and environmentally-driven infrastructure projects – from urban drainage to nature-based solutions like constructed wetlands.
Why join us?
This is an opportunity to take real ownership of engineering works on site, working closely with the site management team to plan and deliver projects safely, efficiently and to a high standard. Health, safety and environmental excellence are central to our work, and you’ll play an active role in supporting these standards on site.
You’ll be hands-on with day-to-day quality assurance activities, including surveying, setting out, inspections and approvals, all aligned with digital design models and modern project systems.
You’ll also contribute to the development of Graduate and Apprentice Engineers, helping to build future talent while developing your own leadership and mentoring skills.
