Mechanical Design Engineer (Building Services)

📍 Cardiff

💰 £45,000 - £55,000

🕒 Full-Time | Permanent

We are recruiting for a Mechanical Design Engineer to join a well-established Building Services consultancy working across a diverse portfolio of commercial, industrial, and public sector projects.

The successful candidate will have proven experience in mechanical building services design and be comfortable delivering projects from concept through to detailed design. This role would suit an Intermediate to Senior level engineer with a strong technical background in HVAC and building services systems.

Key Responsibilities

  • Design and develop mechanical building services solutions including heating, ventilation, air conditioning, public health, and associated systems.
  • Produce mechanical calculations, specifications, reports, and technical documentation.
  • Coordinate designs using Revit and work closely with multidisciplinary project teams.
  • Utilize industry-standard software for mechanical calculations and system design.
  • Attend design team meetings and support project delivery through all stages.
  • Ensure designs comply with current regulations, standards, and client requirements.

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.
