Good understanding of mechanical services (HVAC, heating, hot/cold water systems) and design principles.
*
Strong knowledge of UK building regulations, CIBSE standards, and sustainability frameworks.

Analytical mindset: ability to produce and interpret design calculations.
*
Excellent communication and teamwork skills: able to work collaboratively with multidisciplinary teams.
*
Self-motivated, organised, and able to prioritise in a multi-project environment.
