• Prepare and lead financial reporting, including monthly CVR meetings to ensure accountability, accuracy, and profitability
• Manage procurement of materials, subcontractors, and plant/equipment in collaboration with Commercial & Procurement teams
• Monitor progress, productivity, and resource allocation across multiple trades
• Track project performance against KPIs, identify risks, and implement corrective actions
• Ensure full compliance with H&S procedures, reporting to the Health & Safety Manager as required
• Produce detailed project reports including RFIs, procurement schedules, and progress trackers

Team & Stakeholder Management

• Lead multidisciplinary project teams including engineers, foremen, supervisors, QSs, and external consultants
• Maintain a positive and solutions-focused relationship with clients, design teams, and key supply chain partners
• Represent Designer Group as the senior point of contact for your project(s)

What We’re Looking For

• 5–10 years’ experience managing mechanical installations in large-scale construction projects
• Proven track record as a Project Manager or Senior Mechanical Engineer in M&E contracting
• In-depth knowledge of mechanical building services, commissioning processes, and technical regulations
