We are seeking a Site Agent to join our Highways Contracting team in Leeds.

You will be the main point of contact on site and will act within defined financial authorities to protect contract revenue and performance.

You will lead and motivate site teams, plan and allocate resources (labour, plant, materials and subcontractors), and maintain strong client relationships through regular meetings and site visits.

You will hold an appropriate construction qualification (ONC/HNC/HND or equivalent) and have a minimum of three years’ experience on fast-track motorways, trunk roads or similar highways projects. You must have proven people- and resource-management skills, a good working knowledge of health & safety and HR procedures, experience with NEC/ICE or MAC contracts, and a full clean driving licence. Strong leadership, planning and communication skills, commercial awareness, problem-solving ability and flexibility are essential. You should be a team player, results‑driven, conscientious and committed to continuous improvement and high standards of safety and client service.
