Job Description

Overview

Shape the future of our cities and environments.

You might know us for the great work we do across our wide variety of projects. We're proud to say it's thanks to our people's diversity of thought, expertise and knowledge. And when you join us, you'll be a part of this genuinely collaborative environment, where everyone's voice is valued and treated equally.

We're passionate about what we do, but we don't take ourselves too seriously. Simply put, this a great place to be. So, when it comes to your life outside of work, ask us about our flexible and remote working policies designed to help you get the most out of life.

Our ecology team truly strives to make a positive difference to the natural environment, by working closely with other disciplines across our business to engage in projects from the outset, ensuring ecology is considered at the earliest possible stage. This collaborative working helps to drive forward nature positive schemes that we are proud of. Our award-winning team of over 130 ecologists (including the President of the Chartered Institute of Ecology and Environmental Management (CIEEM) and three CIEEM Fellows) work across a range of exciting habitat creation, research, development and major infrastructure projects; we also design new innovations and help inform policy.

At AtkinsRéalis our people are the foundation of our business and that's why we put our people first. With this in mind, we provide an incredibly flexible and inclusive working environment with staff wellbeing being front and centre of all our decisions. We also understand that not everyone chooses to take the university route in terms of education - we are open to taking on ecologists without a degree and we are working closely with the Chartered Institute of Ecology and Environmental Management (CIEEM) to make entry into the environmental industry more inclusive for all. For us, it is the experience, knowledge and, above all, your ability to fit in well with our existing team of ecologists, that really matters.
