As Planner of Work for Amentum at Sellafield, Seascale, a typical day would center on sequencing and authorizing work packages on a regulated nuclear site: aligning scope, permits, and resources with client and contractor constraints; tracking dependencies and hold points; and updating plans so craft, engineering, and safety stakeholders share one schedule.
