TSA & Change Service Manager

TSA & Change Service Manager – M&A Contract | Outside IR35 | 6 Months | Remote Day rate: Competitive, dependent on experience The Role We're recruiting a TSA & Change Service Manager for a 6-month contract, engaged on an Outside IR35 basis, working primarily remotely. This role sits within the M&A landscape, and requires a candidate with direct M&A experience — specifically around Transitional Service Agreements (TSAs) — this is essential, not preferred. This is a fast-paced, high-autonomy role. We need someone with a genuinely outgoing, proactive character who can get stuck in from day one — no hand-holding, no lengthy onboarding ramp-up expected. You'll be managing sensitive cross-organisational relationships and service dependencies, so confidence, pace, and the ability to build trust quickly are essential. Key Responsibilities * Own and manage Transitional Service Agreements (TSAs) across the M&A lifecycle, ensuring services are delivered, tracked, and exited in line with contractual timelines * Act as the key point of contact between acquiring and divesting/acquired organisations for all TSA-related services and dependencies * Manage TSA governance — tracking service scope, costs, SLAs, exit criteria, and escalations * Lead and coordinate change management activity tied to TSA exit and service transition, ensuring business readiness * Proactively identify risks, service gaps, and exit blockers before they impact critical path or continuity of service * Drive stakeholder engagement and communications at pace across both organisations, without waiting to be directed * Coordinate cross-functional teams (technology, operations, finance, HR) to support TSA service exit planning * Manage vendor and third-party relationships where TSA services are outsourced or supported externally * Report TSA status, risks, and exit progress to senior stakeholders and steering groups * Support cutover planning and post-exit stabilisation for transitioned services Essential Experience * Proven track record as a TSA Manager / Change Service Manager within M&A environments * Direct M&A experience is required, specifically managing Transitional Service Agreements (TSAs) — carve-out, merger integration, or divestiture context * Strong understanding of TSA governance, service exit planning, and cross-organisational service dependencies * Highly proactive, self-starting working style — genuinely comfortable operating with minimal direction * Outgoing, confident communicator who can build trust and drive pace across two organisations simultaneously * Solid grounding in change management and structured delivery methodologies * Strong vendor and third-party management experience * Comfortable managing sensitive, high-stakes stakeholder relationships during separation/integration periods Desirable * Exposure to HR, Finance, or Payroll services within a TSA or M&A context * Experience working alongside Data or Finance transformation teams * Prince2, APM, Change Management (e.g. Prosci), or equivalent certification * Experience within regulated or complex multi-entity organisational environments
