Position: Mechanical Design Engineer

Location: London (with Remote Working available)

Salary: £60,000 + Package

Got a basic grounding in mechanical design and want to be mentored by some of the best in the low-carbon MEP space? Want to work on real-world projects that are cutting carbon in hospitals, schools, and public buildings across the UK? Let’s talk.

We’re working with a fast-growing, forward-thinking renewables contractor (circa £10M turnover) that’s delivering high-impact decarbonization schemes across government frameworks. Typical projects range from £2M–£5M and involve replacing old boiler systems and MEP infrastructure with cleaner, more energy-efficient alternatives — including air source heat pumps, low-temperature heating systems, and upgraded mechanical plant.

They’re now looking for an Intermediate or Trainee Mechanical Design Engineer to support their in-house design team. This is an ideal opportunity for someone early in their career who wants hands-on project exposure and structured progression in a business that’s scaling rapidly and invests heavily in its people.

Role/Responsibilities:

·      Supporting the mechanical design team on low-carbon retrofit projects

·      Assisting with drawings, schematics, and basic calculations

·      Helping to carry out site surveys and gather existing installation data

·      Learning to use design tools such as Hevacomp, IES, and AutoCAD

·      Working with senior engineers to ensure designs meet client and project requirements

·      Coordinating with internal electrical teams and project managers

·      Getting involved in client meetings and technical reviews as experience grows

The ideal candidate:

·      Has a basic understanding of mechanical systems (heating, ventilation, air conditioning, and plumbing)

·      Some experience using AutoCAD or similar design software

·      Either holds or is working towards an HNC/HND or degree in Mechanical Engineering or Building Services Engineering

·      A strong interest in sustainability and low-carbon technologies

·      Organised, enthusiastic, and keen to learn from experienced engineers

What’s on offer:

·      Competitive starting salary with regular reviews as you progress

·      Full support and mentoring from experienced design leads

·      Friendly and supportive team culture

·      20 days holiday + bank holidays

·      Flexible working arrangements between home and site locations
