Inside IR35 Project Administrator Contract Jobs

Organisations bring in Project Administrator contractors to provide the administrative and operational support that keeps projects and programmes running efficiently, managing the documentation, logistics, and coordination tasks that enable project managers and delivery teams to focus on delivery outcomes rather than administrative overhead. The work typically involves maintaining project documentation libraries, scheduling and coordinating meetings, preparing and distributing agendas and minutes, managing action logs, updating project plans and RAID logs, supporting procurement and purchase order administration, managing travel and logistics for project teams, and producing status reports and project communications. Project Administrators are brought in to cover vacancies within project support teams, to provide additional project support capacity on large programmes, or to establish project administration capability at the start of a new programme.
