M&A Integration Manager

The Role 

The Integration Manager is a core member of the IMO and a key part of how Nebius integrates its acquisitions in practice. Working closely with the Senior Integration Manager and Head of IMO, this role takes genuine end-to-end ownership of integration workstreams across M&A programmes and corporate initiatives, from pre-close planning through Day 1 and into post-close execution. The role sits at the intersection of planning, governance, and cross-functional delivery, and requires someone who can hold multiple moving parts together without losing sight of the overall integration outcome. The right candidate brings strong programme management instincts, a natural ability to build relationships across functions, and the discipline to drive workstreams forward independently in a fast-moving environment.

Key Responsibilities

Workstream Ownership

• Lead integration planning and drive execution across assigned workstreams from pre-close through Day 1 and into post-close, keeping dependencies visible and workstreams moving.
• Ensure Day 1 readiness across all assigned workstreams, with critical actions tracked and owners accountable ahead of close.
• Partner with Finance, Legal, HR, Product, Technology, and other functions to maintain cross-functional alignment, holding teams accountable to integration milestones.
• Manage risks, issues, and dependencies proactively, with mitigation plans in place and escalations made early where needed.

Governance & Reporting

• Own workstream governance: RAID logs, decision tracking, meeting cadence, and holding the right people accountable for delivery.
• Prepare decision-ready materials, reports, and presentations for senior stakeholders and leadership forums including SteerCo.
• Flag risks to workstream milestones or integration assumptions early, with a clear view on impact and a proposed path forward.

Stakeholder Management

• Build strong working relationships with functional leads and senior stakeholders within assigned workstreams, acting as a credible and reliable point of contact for integrations.
• Drive change management and cultural integration in partnership with HR and Communications, helping build genuine connections between Nebius and acquired teams.

IMO Contribution

• Contribute to improving integration frameworks, processes, and tools, bringing lessons from each workstream into how the IMO operates.
• Take on structural corporate initiatives including entity changes, migrations, and reorganisations as a core part of the IMO's remit.

Qualifications & Experience

Must-Have

• 5+ years in project or programme management, corporate development, or an integration management function.
• Some exposure to M&A or integration. Depth matters less than familiarity with the context.
• Proven ability to manage complex, cross-functional workstreams simultaneously and independently.
• Strong governance and planning discipline, with experience maintaining structure under pressure.
• Clear and confident communicator, comfortable presenting to senior stakeholders and building trust across functions and cultures.
• Resilient and solutions-focused, comfortable navigating ambiguity and keeping workstreams moving when priorities shift.

Preferred

• Background in technology, cloud, AI, or enterprise software environments.
• Experience working across geographies or in cross-border programme environments.
• Familiarity with IMO or PMO operating models
