Junior M&E Designer

Harmony is on a mission to be the best life safety partner to work with and for. Rated an ‘Outstanding Employer’ by Best Companies in 2025, we are only getting bigger and stronger — and we’re looking for A-players to help us get there. 

We are passionate about making a difference and obsessed with quality. Our goal is to build a world where every resident can sleep safely at night, knowing their home is 100% safe. 

We are looking for a Junior M&E Designer to join our M&E Pre-Construction team in London. You will support the design and specification of mechanical and electrical fire safety systems — including fire alarms, emergency lighting, sprinklers, and associated M&E works — producing drawings, design packages, and technical documentation that underpin our tender submissions and pre-construction programmes across a nationwide portfolio. 

This is a great opportunity for an early-career M&E designer to develop their skills in a fast paced, technically demanding environment, supported by experienced engineers and working on projects that directly contribute to the safety of buildings and residents across the UK.
