* Procuring specialist MEP subcontractors and suppliers, including managing tender processes and contract negotiations
* Issuing applications for payment, assessing subcontractor valuations, and managing variations and change control
* Producing regular cost reports, forecasts, cash flow reports, and final accounts
* Supporting commercial strategy development, working closely with Commercial Leads and Directors
* Contributing to internal process improvements and mentoring junior QSs when needed
* Interfacing with clients, consultants, and supply chain partners to ensure alignment and delivery on expectations
What we’re looking for:
* 5–10 years of Quantity Surveying experience, with a strong focus on mechanical and electrical systems
* Experience on data centre, hospital, pharma, or critical infrastructure projects is highly desirable
* In-depth knowledge of NEC and/or JCT contract forms
* Strong procurement, negotiation, and subcontract management skills
* Ability to handle multiple concurrent workstreams and confidently manage stakeholders
* Proactive, hands-on mentality - someone who thrives in a fast-paced, delivery-focused environment
* Flexibility to travel to site locations across the UK and EU where required
What’s in it for you?
* Join a business delivering end-to-end MEP and technology infrastructure for some of the world’s most demanding data centre clients
* Work alongside a highly experienced in-house team - no outsourcing, no silos
* Clear and achievable progression to Managing QS / Commercial Manager level
* Competitive salary, car allowance, travel expenses, bonus scheme, and ongoing training
* Exposure to large-scale, complex projects in a high-growth sector
