  • Champion the application of appropriate programme and project delivery strategies and commercial vehicles to secure successful business outcomes.

  • Ensure appropriate services to the project are coordinated and delivered through technical, engineering, project controls, commercial, and financial support functions.

  • Maintain project records, information, and history accurately and in line with policy.

  • Ensure learning from experience is captured and apply continuous improvement techniques to project delivery.

  • Significant track record of successfully delivering projects in line with time, cost, and quality constraints.

  • Ability to operate autonomously, with authority, and skilled in developing and maintaining key relationships.

  • Consultancy focus with a proven history of identifying and delivering client requirements, and the ability to scope wider business opportunities.

  • Expertise in P3M practices, methodologies, and techniques, and their appropriate application to varied environments.

  • Highly skilled in the provision of coaching and mentoring.

  • Ability and willingness to attain security clearance, which includes being resident in the UK for the preceding 5 years.

  • Educated to degree level or equivalent in a relevant subject.

  • APM PFQ/PMQ qualification.
