This role is ideal for a technically strong IES modeller who enjoys analysing data, solving complex building performance challenges, and communicating practical solutions to clients. You will play a key part in supporting the company's commitment to measurable carbon reduction, including a targeted 5% decrease in overall emissions for 2024-25.

This is a hands-on technical role within a business that takes sustainability seriously - both in its projects and its own operations.

  • Healthcare cash plan

  • Cycle-to-work scheme

  • Death in service benefit

  • Retail discount scheme

  • Performance-related tax-free bonus (up to 3,600)

What You'll Be Doing

  • Delivering detailed thermal and energy modelling using IES VE

  • Producing clear, well-structured technical reports for clients and internal teams

  • Attending meetings to explain modelling outputs and recommend performance improvements

  • Supporting design teams with evidence-based energy and carbon reduction strategies

  • Contributing to internal carbon reporting and wider sustainability initiatives



Your Key Responsibilities

  • Carry out Part L compliance modelling and dynamic simulation modelling

  • Assess overheating risk and building performance against relevant regulations

  • Interpret modelling data and translate it into actionable design recommendations

  • Work collaboratively with engineers, architects and project stakeholders

  • Keep up to date with building regulations, compliance standards and emerging best practice in low-carbon design



What We're Looking For

  • 3-4 years' experience in building performance or thermal modelling

  • Strong working knowledge of IES VE and building physics principles

  • Confident communicator, comfortable explaining technical findings to non-technical audiences

  • Motivated individual with a genuine interest in sustainability and performance-led design

  • Relevant degree in Building Services, Engineering, Architecture or similar (preferred)
