Senior Building Physics Engineer

The Opportunity

We are recruiting a Senior 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.

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. This is our purpose:
Purpose & Values | Stantec

• Support building physics work streams on complex projects, including thermal, energy, daylight, overheating, natural ventilation, and comfort analysis.
• Develop, review, and optimise energy strategies, operational energy assessments (TM54), and low‑carbon design solutions.
• Provide expert advice on façade performance, passive design strategies, solar control, and building fabric optimisation.
• Ensure compliance with UK regulations (Part L, TM52/TM59, EPC) and contribute to BREEAM, WELL, or LEED credits.
• Produce high‑quality technical reports and clearly communicate findings to clients and design teams.

• Work closely with MEP, architecture, sustainability, and digital engineering teams to integrate building physics principles into design solutions.
• Influence early‑stage design decisions including massing, orientation, glazing ratios, shading, and ventilation feasibility.
• Support the development and adoption of digital modelling workflows and best practices.

• Provide technical guidance to graduate and early‑career engineers.
• Contribute to internal knowledge sharing, technical workshops, and thought leadership.

• Extensive experience in building physics, energy modelling, and performance analysis in a consultancy environment.
• Advanced proficiency with IES-VE (or equivalent) including complex simulation, calibration, and QA.
• Strong technical knowledge of passive design, low‑carbon buildings, façade performance, and dynamic environmental behaviour.
• Experience delivering multi‑disciplinary projects and presenting technical information clearly to clients and teams.

• Experience supporting net‑zero carbon strategies, operational energy modelling, heat decarbonisation, or embodied carbon analysis.
• Familiarity with parametric modelling, digital workflows, or automation tools.
• Mentoring or supporting junior engineers within projects.

• Degree (ideally MSc/MEng) in Building Physics, Mechanical/Environmental Engineering, Building Services Engineering, or related field.
• Chartered Engineer (CEng) via CIBSE, IMechE, or equivalent preferred.
