Are you ready to lead at a strategic level and shape the ecological direction of major infrastructure and development projects? At Assystem UK, you will step into a senior leadership role within our Ecology Consultancy team, influencing projects from early planning through to construction and operation while driving the growth and performance of the ecology practice itself.
