Mechanical Supervisor - South England

Since 2017, Harmony Fire has become the 72nd fastest-growing company in Europe, but we're aiming even higher. It is our mission to continue that growth with the knowledge that the more we grow the greater the impact we can have, reaching more people, increasing our social impact and providing more progression opportunities for our team.

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% compliant.

We now have an opportunity for a Mechanical Supervisor to join our M&E Projects team across the South of England. This is a field-based role requiring flexibility across multiple sites and locations, so a willingness to travel is essential.

Key Aspects of the Role

  • Quality and Compliance Management - Ensure all mechanical works including ductwork, dampers, and associated systems are completed to Harmony and industry standards. Carry out timely checking of works on site and ensure accurate data input and record keeping 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 to the Project Manager 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. Carry out onsite resident liaison where required and communicate works clearly to those affected.
  • 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 relevant H&S paperwork, deliver regular toolbox talks, and maintain a safe working environment through ongoing training and auditing.

Key Requirements

  • Proven experience in a mechanical supervisory or senior trades role, with a background in ductwork, dampers, or associated mechanical systems.
  • Experience running projects to time and on budget across multiple sites.
  • Comfortable working flexibly across the South of England, with a willingness to travel as required.
  • 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.
  • An ambassador for Harmony's values and behaviours on every site.
