Degree‑qualified in Mechanical or Building Services Engineering (or equivalent), with relevant industry experience. Membership of a professional body such as CIBSE, IMechE or IET is expected, with Chartered status or progress towards it desirable. Proficiency in tools such as AutoCAD, Revit, IES or similar is advantageous, alongside knowledge of BREEAM, thermal modelling and engineering calculation software. Experience in sectors such as healthcare, education or defence is beneficial.


Working Environment

This role is based in Belfast, with a hybrid working model typically involving 2–3 days in the office and flexibility for remote working. Occasional travel across the UK and Ireland is required, with opportunities for short international assignments. Flexible working arrangements are supported to promote a healthy work‑life balance.
