Senior Building Services Engineer

About the Role:

As a Senior Building Services Engineer, you will lead the delivery of mechanical building services/ MEP design for energy, industrial and commercial projects within a multidisciplinary building services consultancy environment. The role focuses on the design of base-build and building services systems for complex and regulated facilities, rather than process or manufacturing equipment design.

You will manage the full project lifecycle from concept through to client handover, build strong client relationships, and mentor engineering staff to ensure all deliverables meet the required technical and quality standards.

This is a hybrid role based in Ireland, with attendance at the Dublin office aligned to team and project requirements.
