About the Opportunity
Over recent years, we’ve developed strong and growing relationships with clients across the East and South-East of England. Demand has now reached the point where we’re ready to establish a new regional office — and we’re looking for an experienced Principal Ecologist to help create, shape, and lead it. We don’t have a fixed location in mind for the new office; we’re driven by finding the right person. This is a rare and exciting opportunity for someone ready to take the next step in their career: the chance to build a team from the ground up, while still enjoying the stability, support, and shared resources of an established consultancy. While you’ll have the space to shape and grow this new office, you’ll also be part of a connected, supportive team with a track record of delivering high-quality ecological services across the UK. You’ll take a key role across the business, helping to set technical standards, guide project delivery, mentor colleagues, and contribute actively to the Ethos Management Team.
