Chartered Mechanical Engineer | Building Services | Belfast
Shape the design of complex, sustainable buildings across the UK and internationally.
A multidisciplinary engineering consultancy is looking for a Chartered Mechanical Engineer to join its Building Engineering team in Belfast. This is an opportunity to lead the design and delivery of Mechanical Building Services solutions on technically demanding projects spanning science and technology, rail, higher education, healthcare, residential and industrial developments.
Working within a collaborative design environment, you'll play a key role in developing innovative, low-carbon engineering solutions while working alongside architects, structural engineers and specialist consultants from concept through to project completion.
If you enjoy solving complex engineering challenges, influencing design decisions and delivering high-quality Building Services projects, this role offers plenty of variety and long-term career development.
The Role
As a Chartered Mechanical Engineer, you'll take ownership of the design and technical delivery of Mechanical Building Services systems across a diverse portfolio of projects.
You'll develop building services strategies, coordinate multidisciplinary design teams and ensure projects are delivered to programme, budget and the highest engineering standards.
The role also includes undertaking thermal comfort and building performance analysis, producing technical documentation and mentoring junior engineers as projects progress through design and delivery.
Projects range from highly serviced commercial and public buildings to technically complex science, technology and transport facilities, providing the opportunity to work on challenging schemes where sustainable design is a key priority.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
