Job Details

Senior Mechanical/Building Physics Engineer - Cardiff - to £55k

If you'd prefer a hybrid role of Building Performance Engineering and HVAC Design, you are going to love working at this Building Services Consultancy in Cardiff.

Like you, their Sustainability Associate initially started off their career as a Mechanical Building Services Design Engineer, before switching to Building Performance Engineering / Sustainable Design.

In addition to job security, diverse projects, and a great culture; they can also offer you quick progression to Associate as they only ever promote from within. They are also the only UK Engineering business with a Platinum 'Investors in People' accreditation, which illustrates that they do practise what they preach.

You will join a team of twenty engineers and work closely directly with the Sustainability Associate, something that is just isn't available in the large / corporate engineering practices.

As a hybrid Senior Mechanical and Building Performance Engineer you'll use IESVe or ApacheHVAC to model both complex buildings and entire property portfolios on behalf of their clients. Training will be provided, externally by both IES and CIBSE, as well as internally by the Head of Building Performance, who has been with the practice or over five years.

You'll also use a variety of industry benchmarks such as Passivhaus, Nabers and BREEAM to ensure these buildings operate as efficiently as possible.

You will be able to use your skills as a Mechanical (HVAC) Design Engineer and your passion for Sustainability to go into a remarkably high level of detail and model every aspect of the building. I.e., HVAC systems, occupants, metering strategies, IES and IES Apache HVAC.

You'll be based in their Cardiff office (a 5-minute walk from Cardiff Queen Street station) which does support flexible and hybrid working.

The office is open plan, and the Partners and Directors all share the same space. They encourage all staff to communicate, collaborate and share ideas, which creates a positive and enjoyable working atmosphere.

As the company remains privately owned, rather than having to work to the targets of investors, you will work for a team of Directors who are truly enthusiastic about delivering quality to their clients and are still strongly involved in the day-to-day running of projects.

They are genuinely focused on developing your skills and promoting from within, retaining and developing the best talent.


  • At least five years' experience in Mechanical Engineering
  • Keen interest in NZC design, Passivhaus and Enerfit (Retrofit Version)
  • Advanced IES modelling skills
  • Ideally some familiarity with modelling entire portfolios of buildings.
  • Familiar with stage 2 -3 design

Employee benefits

  • 25 days leave
  • Hybrid working, including 2/3 days from the office and flexi hours (Core hours 9am-4pm)
  • Ongoing training and development (everyone in the office has a training budget allocated each year)
  • CIBSE Approved Training and Development Program
  • Five percent Pension
  • Interest free season ticket Loan, or Cycle to work scheme
  • A genuine opportunity to be instrumental into the future direction and success of the Sustainability team.
