Support the mobilization of connectivity services into new buildings, compounds, and operational areas, from early requirements through to transition and handover.
Engage with Facilities Management, Construction, Logistics, contractor, and operational teams to understand site requirements, physical constraints, sequencing, access requirements, and implementation impacts.
Ensure appropriate governance, assurance, procurement, and approval activities are completed in line with SZC delivery assurance principles.
Support investment cases, project documentation, project mandates, governance submissions, and programme reporting.
Coordinate supplier and contractor activities, challenge plans constructively, and ensure actions, assumptions, dependencies, and delivery commitments are understood and tracked to completion.
Proactively escalate blockers, delivery risks, conflicting priorities, and unresolved dependencies, with clear impacts and proposed options for resolution.
Maintain stakeholder alignment across operational, technical, and project teams, building effective relationships quickly across site and office-based stakeholders.
Support operational transition, business acceptance, and handover activities for connectivity services, including walkthroughs, testing, readiness checks, and lessons learned.

Requirements

Strong understanding of business architecture change within complex, evolving, and delivery-critical environments.
Strong business process analysis and design skills, including the ability to map operational requirements, constraints, dependencies, and handover activities.
Highly organized and proactive, with strong coordination, facilitation, and follow-through across multiple teams and workstreams.
Strong stakeholder management skills and the ability to build relationships quickly across operational, facilities, construction, and technical teams.
Confident challenging suppliers and contractors constructively, ensuring actions, risks, and commitments are clear and progressed.
Comfortable working on a live construction site and able to operate pragmatically in ambiguous, fast-moving delivery environments.
Able to analyze requirements, translate operational needs into clear delivery inputs, and maintain alignment between business outcomes and technical delivery.
Experience coordinating complex infrastructure, facilities, telecommunications, networking, or connectivity projects.
Experience with physical hardware fit design, planning, procurement, and installation activities for infrastructure, networking, telecommunications, or connectivity delivery.
Experience working on large site mobilization programs, ideally in construction, infrastructure, asset-intensive, or operationally complex environments.
Experience working alongside Facilities Management teams, Site Operations teams, Construction delivery teams, network and telecommunications engineers, infrastructure or IT operations teams, and internet and telephony service providers and contractors.
