About the Role

We’re looking for an Intermediate Mechanical Design Engineer to join a busy and fast-growing Building Services team working out of a South London office. With a strong pipeline of high-end residential and prestigious commercial fit-out projects—including work at landmark sites – this is a fantastic opportunity for a technically capable engineer who’s ready to hit the ground running.

You’ll be working alongside a close-knit team, supported by a hands-on director. The atmosphere is collaborative, delivery-focused, and suited to someone who’s self-motivated, organized, and ready to take ownership of their work.

What You’ll Be Doing

• Designing and coordinating mechanical building services systems (HVAC, plumbing, etc.) across high-end residential and commercial projects
• Supporting project delivery from concept through to completion
• Liaising with clients, architects, contractors, and internal design teams
• Attending site and design meetings
• Producing technical drawings and specifications
• Ensuring designs meet current building regulations and sustainability goals

What We’re Looking For

• 3–6 years’ experience in mechanical building services design (consultancy-side preferred)
• Strong technical ability and confidence in taking on project work with minimal supervision
• Proficiency in design tools such as AutoCAD, Revit, and IES
• Understanding of UK Building Regulations and CIBSE standards
• Excellent communication and team collaboration skills

Why Join?

• Flexible hybrid working – work from home and the office as needed
• Exciting, design-led projects with elite-level clients
• Small, growing team where your voice matters
• South London location – ideal for locally-based engineers
• Direct exposure to a variety of projects, allowing you to build a portfolio fast
• Clear opportunity for progression as the company scales

If this sounds like it could be a good fit for you or someone you know, please get in touch today. We would love to be of assistance!
