Senior Manager of M&A Finance Integration

Join Anthropic, a leading AI safety and research company, as a Senior Manager of M&A Finance Integration. In this role, you will oversee the finance function's involvement in each transaction, manage the end-to-end legal entity lifecycle, and drive the finance integration plan for each deal. You will also mentor team members, handle confidential deal information, and design and maintain a legal entity playbook. This is a build-and-run opportunity that requires strong program management skills, cross-functional credibility, and a passion for AI safety.

• Scope and own the finance integration plan for each transaction across every phase, from LOI and due diligence through signing, sign-to-close, and Day 90, spanning finance functions.
• Run the integration operating rhythm: workstream check-ins, issue logs, risk registers, RACI matrices, decision logs, and status reporting to finance leadership.
• Build and run the end-to-end entity setup process: decision documentation, incorporation, tax registrations, banking, ERP entity creation, functional-currency assessment, payroll or employer-of-record bridge, and statutory / compliance calendar onboarding.

• The ideal candidate has operated in a similar function at a high-growth technology company, brings enough accounting fluency to know when a closing spreadsheet or entity plan looks wrong, and thrives on building rigorous, repeatable processes while deals are live
• Demonstrated end-to-end ownership of at least two finance integration projects or entity set up projects, from planning through post-close execution, including project plan ownership and executive reporting
• Working accounting fluency across the areas your stakeholders own: the close calendar, chart of accounts, intercompany, statutory reporting, purchase accounting fundamentals, and the finance implications of common deal structures (asset vs. stock, acquihire vs. strategic, full integration vs. standalone)
• Experience with ERP systems (NetSuite, Oracle, SAP, or equivalent) in an acquisition and migration context
• Cross-functional credibility with Legal, Tax, People, Corporate Development, and Finance sub-functions, and the ability to drive outcomes across competing timelines and risk tolerances
• Strong program-management capability: comfortable scoping ambiguous work, owning multiple parallel workstreams, and managing to milestones without extensive oversight
• Excellent written and verbal communication, with the ability to distill complex operational issues into clear, decision-ready briefings
• Comfort operating under deal-environment time pressure and confidentiality, with sound judgment when processes are being defined in real time
• Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience
• We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed
• Have worked with standalone-subsidiary integration models, consolidation bridges, and equity-method investments
• Bring international entity experience: new-jurisdiction setup, statutory audit and local GAAP obligations, employer-of-record bridges, transfer pricing and intercompany agreements
• Have built or significantly contributed to a finance integration playbook, template library, or integration management office infrastructure from scratch
• Hold a CPA, ACA, ACCA, or CA qualification
• Be genuinely excited about AI safety and aligned with Anthropic's mission to build reliable, interpretable, and steerable AI systems
• 10+ years in finance, accounting, or finance operations, with at least 3 years running cross-functional programs at a high-growth technology company, with a focus in M&A integration or legal entity programs
• Be an active user of AI tools in their own workflow and excited to push program management toward automation
