Director, M&A Finance Integration

About the role

Anthropic is seeking a dedicated finance integration lead to own the finance function's role from post-signing phase through Day 1 readiness, post-close integration execution, and ongoing playbook development.

This is a rare build-and-run opportunity. You will partner closely with the Corporate Development Integration Lead as the dedicated Finance lead within the Integration Management Office (IMO), while reporting to the Head of Corporate Accounting. You will be the connective tissue between deal teams and the Finance organization, and the primary architect of Anthropic's scalable M&A finance integration playbook.

The ideal candidate has operated in a similar function at a high-growth technology company, and thrives on building rigorous, repeatable processes in fast-moving, ambiguous environments.

Responsibilities:

Integration Planning & IMO Finance Leadership

• Serve as the Finance function lead within the IMO, coordinating the Finance workstream alongside the Corporate Development Integration Lead who owns overall IMO governance
• Design end-to-end Finance integration plans for each transaction: accounting close, financial reporting, ERP/systems migration, treasury, payroll, FP&A alignment, and tax considerations
• Define Day 0 through Day 100 Finance milestones with clear owners, dependencies, and escalation paths
• Build and maintain project plans, issue logs, risk registers, and RACI matrices for the Finance workstream; own reporting into the IMO steering committee
• Coordinate cross-functional Finance dependencies spanning Accounting, Tax, FP&A, Treasury, Procurement, Payroll, and IT/ERP

Day 1 Readiness & Post-Close Execution

• Own Finance Day 1 readiness and drive execution through the first 100 days, ensuring acquired entities are fully onboarded with zero disruption to close cycles
• Execute Day 1 Finance checklist: bank account access, payroll cutover, AP/AR continuity, ERP provisioning, and expense policy communication
• Oversee purchase price accounting and opening balance sheet preparation in accordance with ASC 805, coordinating with external valuation advisors as needed
• Drive alignment of acquired entity accounting policies to Anthropic's standards: revenue recognition, cost allocation, capitalization thresholds, close calendar, and chart of accounts
• Serve as the primary Finance point of contact for acquired Finance teams during transition

Playbook Development & Finance IMO Infrastructure

• Develop and maintain a modular Finance Integration Playbook covering all acquisition types, including due diligence checklists, Day 1 readiness plans, 30/60/90/100-day task libraries, systems migration runbooks, and PPA templates
• Build KPI frameworks to measure Finance integration success: close cycle achievement, systems migration completeness, synergy capture rates, and audit-readiness
• Conduct post-integration retrospectives after each deal; capture lessons learned and feed insights back into playbook refinement
• Identify and implement tooling to support integration project management and repeatable reporting cadences

Stakeholder Management & Communication

• Act as a trusted advisor to finance stakeholders on Finance integration progress, risk exposure, and key decision points
• Coordinate across Finance sub-functions (Controllership, Tax, Treasury, FP&A, Procurement) and cross-functional partners (Legal, HR, IT, Engineering) to drive workstream execution
• Manage relationships with external advisors including audit firms, tax advisors, valuation firms, and ERP implementation partners
• Communicate integration status to Finance and executive leadership through clear dashboards, steering committee packs, and written briefings
• Manage and coordinate direct engagement with the target executives (e.g. CEO) during due diligence and integration planning efforts prior to deal close

You may be a good fit if you have:

• 12+ years in finance or accounting, with at least 3–5 years focused on M&A transactions and post-close integration at a high-growth technology company
• Demonstrated end-to-end ownership of Finance integration workstreams — from due diligence through Day 100 — including IMO participation, project plan ownership, and executive reporting
• Deep technical accounting fluency: US GAAP, purchase accounting (ASC 805), revenue recognition (ASC 606), and the accounting implications of common deal structures (asset vs. stock, acquihire vs. strategic)
• Prior experience with coordinating finance workstreams prior to deal close and immediately after (e.g. closing spreadsheet, transfer of account ownership, etc.)
• Strong project management capability — comfortable owning multiple parallel workstreams and managing to milestones in fast-moving environments
• Cross-functional credibility with Legal, Tax, HR, IT, and Engineering, and the ability to drive Finance integration outcomes across organizational boundaries
• Excellent written and verbal communication skills, with the ability to distil complex accounting and operational issues into clear executive briefings
• Experience with ERP systems (NetSuite, Oracle, SAP, or equivalent) in an acquisition and migration context

Strong candidates may also:

• Have prior experience at a technology company with an active M&A programme — either in-house or on secondment from a Big 4 or advisory firm
• Have built or significantly contributed to a Finance Integration Playbook, template library, or IMO infrastructure from scratch
• Bring familiarity with acquihire-specific Finance integration challenges: equity plan rollovers, benefits cutover, and payroll transitions for small, high-value engineering teams
• Have exposure to international M&A and cross-border integration: multi-entity consolidation, statutory filing obligations, and local GAAP considerations
• 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
