6. Deliver regular updates to the Operational Readiness Manager, achieving key milestones
7. Ensure robust safety practices for all test and commissioning activities
8. Witness FAT, SAT, and Setting to Work (STW) activities in both active and inactive environments
9. Resolve test failures and manage change to commissioning schedules, resources, and forecasts
10. Drive compliance with LC21 (Commissioning) and associated governance requirements
11. Lead integration of commissioning with the overall programme delivery strategy
12. Demonstrable experience developing commissioning and test strategies
13. Strong knowledge of V&V methodology (especially the V model)

15. Deep understanding of commissioning procedures, LC21, and site safety protocols
16. Excellent project delivery experience—ideally within nuclear, defence, or similarly complex environments
17. Confident communicator, both written and verbal, with experience working across cross-discipline teams and with clients
18. High-level organisational and project management skills
