We are looking for an experienced Project Principal/Project Director with a background in the water sector and demonstrable commercial acumen to join our International Water Portfolio as a senior member of our team.

We are an equal opportunity employer and value diversity at our company. We do not discriminate and take positive steps to create an inclusive culture.
