Job description

Mechanical Building Services Engineer (Intermediate / Senior)

Design it. Own it. See it built.

If you’re a mechanical building services engineer who’s tired of being one name on a drawing register at a big consultancy, here’s the alternative. An independent, director-led M&E consultancy where your designs go from first sketch to commissioning with your fingerprints all over them, and the person running the business knows exactly what you’ve delivered.

Why this one’s different

• Independent and personal. No layers of associates between you and the decisions. The practice was built on giving every client, big or small, a properly professional but personal service, and that’s how they treat their engineers too.
• Low carbon is the day job, not a slide in a pitch deck. The director is a Chartered Environmentalist, and the team has been ripping fossil fuel plant out of school estates and replacing it with CO2 heat pumps. They’ve even put their own PV and battery storage to work charging the company EV.
• Proper variety. Education, student accommodation, commercial, healthcare, industrial and public sector. A new-build sports hall one month, a full strip-out and refurb the next.
• Real progression. A growing team with a clear route to Senior and Principal, with your CIBSE or IMechE membership and CPD backed.

What you’ll be doing

• Leading mechanical design from concept to detailed design: HVAC, heating, cooling, LTHW, CHW and public health
• Running the numbers yourself: heating and cooling loads, hydraulics, pipe sizing
• Laying out plantrooms and selecting the kit
• Writing the specs, reports and technical schedules
• Coordinating in Revit / BIM with architects, electrical and the wider design team
• Getting out from behind the screen for client, design team and site meetings
• Seeing projects through construction, commissioning and handover, and sorting contractor queries along the way
• At Senior level, bringing junior engineers on

What you’ll bring

• A strong mechanical building services design background from consultancy or Design & Build
• Confidence in Revit and AutoCAD
• Hands‑on experience with MagiCAD, Hevacomp, IES VE or TAS
• Real technical depth in HVAC and mechanical systems
• The ability to juggle multiple projects and hit deadlines
• The communication skills to hold your own with clients, contractors and the design team

What’s on offer

• £50,000 to £70,000 depending on experience, plus benefits
• CIBSE / IMechE membership support
• CPD and technical training
• A genuine path to Senior and Principal
• Technically challenging projects where your input actually changes the outcome
• A supportive, collaborative team that’s growing
