The Opportunity
Stantec’s Nuclear team is entering an exciting phase of growth. Having secured positions on several significant multi-year frameworks, we are expanding our capability to support some of the most complex and impactful projects across the nuclear sector.
We are looking for a Principal or Senior Principal Consultant in Environmental and Radioactive Waste Management to join our growing team. With opportunities to be based in Warrington, Manchester, Glasgow, Bristol, Northampton, or Cambridge, this role offers the chance to work with a wide range of clients including Gigawatt-scale and Small Modular Reactor (SMR) developers, nuclear site licensees, waste management organisations, regulators, and the defence sector.
This is a unique opportunity to influence the future of the nuclear industry, supporting projects across the entire nuclear lifecycle - from new build and operational facilities through to decommissioning and the safe management of radioactive waste.
About The Role
As a Principal or Senior Principal Consultant, you will play a senior leadership role within our Nuclear team, providing specialist environmental and radioactive waste consultancy services to clients across the UK and internationally.
- Lead the delivery of technically complex projects, supporting nuclear new build and decommissioning programmes through the development of waste strategies, environmental safety cases, permitting strategies, and regulatory compliance programmes.
- Help clients navigate environmental and radioactive waste management challenges while ensuring compliance with evolving regulatory requirements.
- Drive the continued growth of the business through business development activities, ranging from identifying opportunities and developing client relationships to leading bids and preparing technical proposals.
- Take an active role in developing our people, mentoring colleagues, building team capability, and supporting the growth of a high-performing consultancy team.
- Contribute to continuous improvement initiatives, helping to shape internal processes, standards, and procedures to ensure we continue to deliver excellence across our projects and services.
Your Impact
In this role, you will directly influence the safe, sustainable, and effective management of radioactive materials and environmental challenges across some of the UK's most important nuclear programmes. Your advice and technical leadership will support clients in making informed decisions that balance operational, environmental, regulatory, and commercial considerations.
- Help organisations successfully navigate complex challenges throughout the nuclear lifecycle.
- Contribute to the safe decommissioning of legacy facilities, the development of next-generation nuclear technologies, and the responsible management of radioactive waste.
- Play an important role in shaping the future of our Nuclear business.
- Strengthen our market position, expand our client base, and support the development of the next generation of nuclear consultants.
