Build the future of low-carbon building services

Are you the kind of Mechanical Design Engineer who gets excited by complex plantrooms, heat pumps, energy centres and design that actually gets built?

This is not a “design in isolation” role.

You’ll be joining a specialist offsite MEP and low-carbon building services business delivering major decarbonisation, modular plantroom, district heating and commercial MEP projects across the UK and beyond.

You’ll take the lead on mechanical design from early-stage concept through detailed design, fabrication support, installation interface and commissioning input.

What you’ll be working on

Heat pumps, ASHP, WSHP and low-carbon heating systems

Energy centres, packaged plantrooms and modular MEP solutions

LTHW, DHW, pump sets, thermal stores, calorifiers and heat exchangers
