Job Description

This role is central to supporting Heathrow’s world‑leading expansion by designing and assuring the utility systems that underpin the airport today and into the future. As a Senior Design Engineer – Utilities, the role plays a key part in shaping thermal, electrical, potable water, foul water, and stormwater networks that support terminals, airfield assets, highways, structures, and the wider passenger experience across the expansion programme. Working within one of the most complex infrastructure environments globally, the role is responsible for delivering integrated, coordinated, and fit‑for‑purpose utility design solutions that align with Heathrow’s sustainability ambitions and evolving operational needs. Utilities form a critical foundation of airport operations, and decisions in this role directly influence safety, resilience, carbon performance, customer experience, and long‑term asset value.

The role ensures that safe, secure, and efficient construction, operation, and maintenance are embedded from the earliest stages of design. This includes a strong focus on whole‑life performance, climate resilience, future capacity, and adaptability enabling utility systems to respond to changes in technology, regulation, and demand while maintaining operational continuity. A system‑wide perspective is essential. Utility solutions must align with Heathrow’s design principles, integrate effectively with highways, structures, and buildings, support airline and passenger growth, meet planning requirements, remain cost‑effective, and be delivered to defined timescales. Through this work, the role contributes to the development of a resilient and high‑performing utility network capable of supporting one of the world’s busiest airports through its next phase of growth.
