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.

This is your opportunity to lead from the front in a once‑in‑a‑generation transformation of the UK water sector. As a Principal Wastewater / Urban Drainage Modeller, you won’t just deliver projects—you’ll shape resilient, future‑ready communities.

You will be the technical authority. The problem‑solver. The mentor. The trusted voice at the table.
