Senior Principal (Associate Director) Ecologist

Biodiversity is no longer a box to tick on an infrastructure project. It is a central part of how the best work gets designed, delivered and measured. At Stantec, our Ecology Team approaches it that way, combining scientific rigour with genuine innovation to deliver outcomes that make a real difference to the natural environment.

We are looking for a Senior Principal Ecologist to join a growing team that is ambitious, collaborative and deeply committed to doing ecology well. If you are ready to take on more complex work, grow your career and be part of something that is genuinely building towards a better natural environment, this could be exactly the right move.

About The Role

You will work closely with our national team across a varied portfolio of projects spanning multiple sectors, with strong links to our existing water utility partnerships and an active pipeline of new opportunities.

Day to day, you will lead on projects across Scotland. That work will span the full range of ecological consultancy: conducting surveys and assessments, designing and implementing mitigation and enhancement measures, applying for and obtaining protected species licences, and contributing ecological input to multidisciplinary project teams alongside planning, engineering and design colleagues.

As a senior member of the team, you will also play an important role in mentoring junior ecologists, helping them develop the skills and confidence to take on more complex work of their own. You will have real autonomy in how you approach your work, with the backing of an experienced team and access to training and networking opportunities that support your continued professional growth.

Your Impact

The projects you work on here will shape how biodiversity is considered, protected and enhanced across some of the UK's most significant infrastructure programmes. Your ecological assessments, mitigation strategies and species licences will translate directly into better outcomes for habitats and wildlife that cannot advocate for themselves.

Beyond the projects, your influence will be felt in the team around you. By mentoring junior colleagues and helping to build a culture of technical curiosity and high standards, you will leave a mark that lasts well beyond any individual survey or report.
