• Collaborating with internal design teams and external clients to influence project direction and improve building performance
• Contributing to operational energy analysis in line with the London Plan and GLA guidance
• Getting exposure to Climate-Based Daylight Modelling, Overheating assessments, and net zero strategies

• Expert IESVe skills (dynamic simulation, Part L, EPCs)
• Comfortable using CIBSE guidance, TM54, TM52, TM59, TM65 etc
• Confident communicator, able to engage with clients, present findings, and collaborate with multidisciplinary teams

• Committed to CPD, willing to attend CIBSE courses, and sustainability workshops.

What’s in it for you:

You’ll be joining a supportive, forward-thinking MEP Consultancy with around 100 MEP and Energy and Sustainability Engineers. Your voice will be heard and your input will shape how buildings are designed, delivered, and operate in use.

You’ll enjoy working in a relaxed, collaborative culture and will have exposure to interesting projects across the commercial, residential, education, healthcare, and mixed-use developments.

You’ll have a clear path to Director and be fully backed and supported by the current Partners and Associates.
