Electrical Site Supervisor

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 have an opportunity for an Electrical Supervisor to join our M&E Projects team across Scotland. You will oversee the installation, testing, and commissioning of electrical fire safety systems including fire alarms, emergency lighting, and associated systems across a range of residential and commercial sites. This is a field-based role requiring flexibility across multiple sites — a willingness to travel across Scotland is essential. This is more than a trades role. It is about bringing the right energy, accountability and resilience to our mission of saving lives through fire and height safety — and setting the standard for quality and safety on every site you walk onto. Quality and Compliance — Ensure all works are completed to Harmony and BMTRADA standards. Carry out timely checking of works on site and ensure accurate data input throughout. Site Management — Oversee site set up and sign off, stock management, delivery of prelims, pre-condition surveys, and post inspections to allow for final sign off by the Project Manager. Identify and flag variation opportunities immediately. People Management — Resolve day-to-day issues, boost team morale, manage conflict, and identify resource requirements. Maximise the productivity and utilisation of colleagues and subcontractors on site. Quality Control — Ensure all works are certifiable and compliant, delivered to both client and Harmony expectations. Carry out regular spot checks and record findings accurately. Client Management — Attend pre-start meetings and ensure the site is always tidy and representative of Harmony’s brand. Communication — Provide regular progress updates to the Project Manager and weekly reports to the client. Attend calls as needed and agree reporting frequency with the Project Manager. Health and Safety — Implement Harmony’s H&S policy across all sites. Induct new trades, ensure completion of all H&S paperwork, deliver regular toolbox talks, and maintain a safe working environment at all times. An A-player mindset — high standards, extreme ownership and the drive to do things properly, the first time. Proven experience in an electrical supervisory or senior trades role within fire safety or a closely related discipline. Hands-on experience with fire alarm systems and emergency lighting installations, including testing, commissioning, and certification to BS5839 and BS5266. Experience running projects to time and on budget across multiple sites. Comfortable working flexibly across Scotland, with a willingness to travel as required. Strong understanding of relevant electrical regulations and compliance requirements. A strong problem solver who sees things through to completion. Ability to build and maintain good working relationships with clients, subcontractors, and colleagues. Proactive, confident, tenacious, and resilient.
