Role Purpose

Located within the Solirius Reply Service Centre, this multi-skilled disciplinary role, champions service management best practices across the organisation.

When deployed on assignment, the Senior Consultant guides our clients (predominantly public sector) through the critical phase between programme / project delivery and operational stability.

Operating across diverse digital landscapes (cloud platforms, multi-supplier environments and legacy estates), this role ensures technology services successfully transition, pass service assessments (GDS and AiS levels) and migrate into live running without disrupting citizen-facing services or client internal operations.
