    Mechanical (Building Services) Engineer - To £48K

    Quality of delivery, quality of staff, innovative projects, and a great company culture. These are the founding principles of this multi-disciplinary engineering consultancy based near Liverpool Street.

    Quality runs deep through the practice, and every project is overseen by a director all the way through the various RIBA stages. They produce quality designs that are low in energy and carbon, are properly coordinated and, actually fit within the space that was allocated by the client.

    In terms of recruitment, they only employ permanent staff with stable employment histories, as they would prefer to turn work away rather than employing average engineers to just churn out poor quality designs.

    Innovation exists across everything they do, they analyse every completed project, compare how the building is performing in use, and then use building performance engineering to improve the next project. They also continuously research and invest in new and emerging technologies, in order to make their existing software, processes or templates more efficient.

    And, they also adopt a bold approach to building design, never shying away from the opportunity of trying something totally new, to solve an issue or overcome a challenge. Recent examples include their use of stone bearing masonry rather than steel, their investment in R&D into the use of advanced phase change materials or their ability to use CLT on larger, complex structures.

    In terms of culture, the founding partners remain hands on and actively encourage all employees to make suggestions on how things can be improved. They operate an open plan studio environment, with MEP Engineers siting alongside the structural engineers, civil engineers, and BIM staff, which ensures constant collaboration. They have weekly and monthly social activities, and provide all staff with an annual bonus, and an annual salary review and increase.

    As an Mechanical Engineer, you'll get involved in designing and modelling a variety of low carbon, interesting buildings such as theatres, museums, galleries, schools, castles, cinemas, offices, churches, universities, and data centres.

    You'll work as part of a friendly, experienced, and supportive team of around 30 engineers on one off projects, typically from concept all the way through to construction.

    You will attend design team and site meetings, and liaise directly with clients, architects, and specialist external consultants. You will also carry out heating and cooling loads, size plants, ducts, or pipes, use Revit MEP to produce 3D models, and also ensure all projects adhere to CIBSE guidelines, British standards and also promote a circular economy.


    • At least two years' experience as a Mechanical Design Engineer,
    • Previous experience working directly with Architects.
    • Comfortable communicating technical terms, to a non-technical audience.
    • Easy to work with, able to work as part of a team.
