You will play a key part in ensuring accurate records, smooth communication, and efficient site operations.

This long‑term project spans 9‑12 years and forms part of a major waste management contract similar to our successful work at Hinkley Point C. Initially, operations are managed directly from the client’s site before transitioning to a dedicated Waste Consolidation Centre.

  • Maintain and update customer, contractor, and operational data across relevant systems
  • Respond to internal and external enquiries in a professional and timely manner
  • Support booking and coordination of waste movements and lift requirements when required
  • Manage and update document control systems (e.g. Teamcentre), ensuring records are current and accurate
  • Support reporting requirements by extracting and compiling basic operational data when needed

Essential Requirements

  • Previous experience in an administrative or office‑based role
  • Strong organisational skills with good attention to detail
  • Confident using Microsoft Office (Word, Excel, Outlook, Teams)
