Do you have a passion for Civil Engineering and are you driven to create solutions for the unprecedented climate, environmental, and efficiency challenges facing our communities? Then make a real difference and join the award-winning team at Stantec!

• Driving Environmental Sustainability: Play a direct role in enhancing local ecosystems and river health by minimizing pollution risks, reducing carbon footprints in design, and implementing sustainable drainage and circular water solutions.

• Shaping Next‑Generation Infrastructure: Directly influence how critical infrastructure is delivered across Northern Ireland and the UK during AMP8—helping modernize aging assets with smart, efficient, and innovative civil engineering solutions.

• Building Lasting Legacy: Leave a tangible, positive footprint on the environment and society, delivering essential public assets that will safely serve communities for generations to come.
