Benefits
This is a chance to run live sites for one of the UK’s fastest-growing life safety specialists — the kind of work where you can see what you’ve delivered at the end of every week and know it makes residents safer. At Harmony, we ask a lot — and we give a lot back. The hours are real, the standards are high and the work is demanding, but for those who show up, deliver and go the extra mile, the rewards follow. A-players here enjoy a competitive salary, a Personal Development Plan with ongoing training and coaching, unlimited holiday, a bonus scheme paying up to 50% of annual salary, enhanced maternity and paternity, lunch, snacks and refreshments on us every day at the office (fresh fruit and Takeaway Fridays included), a team social budget, cycle to work, an auto-enrolment pension, two major company events a year and our Reward and Recognition scheme — including European mini-breaks for those who go above and beyond. It is a collaborative, high-energy environment focused on doing things the right way — technically, practically and safely — and none of it is a perk for showing up; it’s what we share with the people pulling the business forward.
Harmony is an equal opportunity employer. We consider all applicants for employment regardless of age, disability, sexual orientation, gender identity, family or parental status, race, colour, nationality, ethnic or national origin, religion or belief. We want everyone who works with us to feel valued and to make a difference.
