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.
