Senior Site Supervisor

Department: Building Fabric - Delivery

Employment Type: Full Time

Location: Dudley

Description

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 now looking for a Senior Supervisor to lead our Building Fabric site teams across our West Midlands pod. Based out of our Dudley office, you will take ownership of how supervisors and site teams deliver passive fire protection and building fabric works across a range of residential, social housing and commercial sites — making sure every job runs to programme, quality and safety standards without compromise.

This is a step up from running a site yourself. You will be the supervisor of supervisors — coaching, auditing and holding the line on standards across multiple live projects in the Dudley pod, with the Project Manager and Project Director relying on you to be their eyes, ears and intervention point on the ground.

This is more than just a site role. It is about bringing the right energy, accountability and resilience to our mission of saving lives through fire and height safety.

Key Responsibilities

Lead and oversee a team of Site Supervisors across multiple live Building Fabric projects in the Dudley / West Midlands pod.
Coach, develop and hold accountable the supervisors reporting to you — setting clear standards and making sure they’re met on every site.
Drive consistency in quality, programme and safety across all projects in the pod, intervening early when standards slip.
Carry out site quality audits and inspections, identifying non-conformances and making sure they are resolved at root cause, not papered over.
Ensure all Building Fabric works are delivered to Harmony standards and the relevant industry codes (passive fire protection, fire stopping, fire doors and associated works).
Support Project Managers with site set-up, mobilisation, stock management, pre-condition surveys and final sign-off across projects.
Spot and flag variation opportunities to the Project Manager early, protecting margin and programme.
Be the senior site presence for clients across the West Midlands — attending pre-start meetings, walking sites with clients and consultants, and representing Harmony’s brand on every visit.
Implement and police Harmony’s H&S policy across every site in the pod, leading toolbox talks, RAMS reviews and safety audits.
Coach the next generation of supervisors — training, mentoring and supporting their progression within the business.

Skills, Knowledge and Expertise

An A-player mindset — high standards, extreme ownership and the drive to do things properly, the first time.
Proven experience in a senior site supervisory, site manager or working foreman role within passive fire protection, building fabric, fire stopping or a closely related specialist discipline.
Hands-on background in Building Fabric — passive fire protection, fire stopping, fire doors and associated works — with the credibility to challenge supervisors and trades on technical detail.
Experience leading or coaching other supervisors, not just running your own site.
Strong working knowledge of relevant standards, RAMS and site H&S requirements.
SMSTS, CSCS Black/Gold card and First Aid at Work (or willing to obtain).
Excellent communicator, able to manage clients, consultants and subcontractors with confidence and clarity.
A strong problem solver who sees things through to completion at root cause.
Based within commutable distance of our Dudley office, with regular site presence required across the West Midlands region.
Full UK driving licence.
