About the Project

We are seeking a seasoned Transition Workstream Lead to spearhead a critical workstream as part of an HR Transformation implementation. This is not a "steady-state" role; we need a battle-tested Implementation Lead who thrives in high-pressure environments and has a proven track record of rescuing or driving difficult, large-scale HR transformations.

The successful candidate will be the architect of the transition, working strictly within the Deloitte Target Operating Model (TOM) framework to ensure a seamless shift from project phase to Business As Usual (BAU).

Essential Skills & Experience:

Strategic Implementation & GTOM Governance

• Framework Alignment: Drive all workstream activities in strict accordance with the GTOM framework, ensuring global scalability and process standardization.
• Gate Ownership: Take full accountability for the execution and successful passage of all GTOM gates supporting the transition.
• Project Controls: Provide expert input into the program workplan, maintaining rigorous RAID logs (Risks, Assumptions, Issues, Dependencies) and delivering transparent status reports to executive leadership.

Transition, Cutover & Hypercare

• The Blueprint: Define and execute the end-to-end cutover plan, managing complex data migration cycles, business go live activities and technical environment readiness.
• Operational Readiness: Design and implement a robust Support Model that bridges the gap between implementation and long-term BAU operations.
• Hypercare Leadership: Own the definition and execution of the Hypercare approach, providing high-touch leadership during the critical post-go-live window to ensure system stability and user adoption.

Team Leadership & Stakeholder Management

• Workstream Oversight: Lead, mentor, and oversee a dedicated workstream team, ensuring day-to-day delivery remains on track.
• Conflict Resolution: Serve as the primary point of escalation for workstream issues, resolving technical and functional roadblocks with urgency.
• Cross-Functional Collaboration: Facilitate critical discussions across different teams (IT, HR, Payroll, Finance) to manage interdependencies and ensure a cohesive global rollout.

The Ideal Candidate

1. Experience: Minimum 7+ years of HR implementation experience, specifically leading workstreams through the full project lifecycle.
2. Experience working with Deloitte IT, extensive network within the UK IT organisation
3. The "Rescue" Mindset: Proven experience delivering difficult or high-stakes implementations. You should be comfortable walking into complex environments and bringing order to chaos.
4. Domain Expertise: Deep understanding of HR solutions (e.g., SAP, ServiceNow, Avature) and the intricacies of data migration.
5. Framework Fluency: Prior experience working within a big 4Technology Operating Model or similar enterprise-scale governance structure.
6. Communication: Exceptional stakeholder management skills, with the ability to influence senior HR leadership and manage third-party implementation partners.

Definition and execution of Support Models

• Expertise in Data Migration cycles and technical cutover sequencing.
• Strategic management of Hypercare phases.
• Mastery of Deloitte Technology Operating Model gate requirements.
