Senior Program Manager; M&A San Francisco, CA

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

Anthropic is seeking an M&A People Program Manager to join our People PMO team — a nimble team of organizational architects who take the company's most pressing people and culture challenges from 0 to 1. Anthropic's growth includes acquisitions, and we need a dedicated operator to serve as the single point of coordination between Corporate Development and all People functions — from due diligence through integration.

In this role, you'll partner closely with Corp Dev and drive cross‑functional execution across Recruiting, People Partners, People Operations, Workplace Immigration, Employment Legal, and Internal Communications. You'll help build the systems and playbooks that don't exist yet, ensure every workstream is properly sequenced, and create a strong experience for both acquirees and the Anthropic team members supporting them. This is a highly operational role that requires someone who thrives under compressed timelines, moves fast without sacrificing accuracy, and can navigate complex stakeholder dynamics with ease.

• Serve as the single DRI for all People‑side M&A activity from confirmatory due diligence through integration, partnering closely with the Corporate Dev team from deal kickoff.
• Coordinate across Recruiting, People Partners, People Operations, Workplace Immigration, Employment Legal, and Internal Communications to ensure all work streams are aligned and sequenced correctly.
• Develop and maintain integration playbooks, timelines, and checklists that prevent errors (wrong entity hires, immigration gaps, missed onboarding windows) and reduce reactive scrambling.
• Manage and iterate on the program to ensure you’re meeting stakeholder needs, evolving with the business and providing a strong experience to acquirees.
• Act as a trusted partner to Corp Dev, helping them understand people implications of deal decisions and timeline trade‑offs.
• Serve as a strategic thought partner to improve cross‑functional M&A work streams beyond People where applicable.
• Build relationships across People functions so you can mobilize the right people quickly when timelines compress.
• Build the infrastructure that doesn't exist yet: intake processes, due diligence checklists, integration tracking, and post‑close retro frameworks.
• Identify recurring failure modes and implement upstream fixes so each deal goes more smoothly than the last.
• Document learnings and create shared resources that enable the broader People team to execute confidently.

• Have 8+ years of experience in program management, HR operations, and/or M&A integration, with at least some experience on the People/HR side of transactions.
• Are exceptionally organized and calm under pressure — you know how to manage compressed timelines without cutting corners that create downstream risk.
• Can hold complexity across many work streams simultaneously and know how to sequence interdependencies correctly (immigration before offer letters; entity verification before onboarding).
• Communicate clearly and directly, especially when timelines are tight or information is incomplete.
• Know how to build credibility quickly with senior stakeholders across functions who don't report to you.
• Are comfortable operating with minimal oversight and creating your own structure when none exists.

• Direct experience managing people integration in M&A transactions, including offer processes, onboarding, and immigration coordination.
• Familiarity with multi‑entity hiring complexity, visa/immigration considerations, or employment legal basics.
• Background in fast‑growing technology companies where deal timelines are compressed and processes are still being built.
• Experience working closely with Corp Dev or M&A teams in a cross‑functional capacity.
