Principal Building Physics Engineer

The Opportunity

We are recruiting a Principal Building Physics Engineer to help lead and grow our national capability across the Southwest. Working closely with the senior leadership team, the role will ideally require weekly travel to the Plymouth office.

About The Team

Our Building Physics specialists play a critical role in shaping our design strategy, influencing early-stage decisions, driving energy performance, and ensuring our solutions stand up to technical scrutiny. We work across a broad portfolio that includes science & technology, healthcare, education, commercial, transport hubs, and regeneration projects throughout the UK and internationally.

At Stantec, we create the connections that get people and communities moving. Across our Buildings & Sustainability teams, we design high‑performing, low‑carbon, human‑centred environments. Our collaborative culture brings together engineers, designers, modellers and sustainability specialists to deliver buildings that are resilient, efficient, and ready for a net‑zero future.

When we say community, we mean everybody with a stake in the work we do – from the clients we collaborate with across many sectors, to the populations we reach, to the thousands of us working together to serve them.

Our promise, our values, and our voice support our purpose and guide us in all that we do.

We are defined by more than our services. We are defined by what we stand for, what we believe, and why we do what we do. We make a difference in the world by creating communities.
