Job Description

About the role

As Manager, Customer Success — GSI at Anthropic, you'll lead the front-line team responsible for Anthropic's most complex and highest-leverage customer relationships: the Global Systems Integrators and consulting firms who deploy Claude inside their own firms, in addition to, extending Anthropic’s scale by deploying Claude across their clients. You'll directly coach and develop a team of 5–8 Customer Success Managers who drive value across our entire product portfolio e.g. Claude Platform, Claude Code and Claude Cowork,  while building and maintaining strategic relationships with our flagship partners.

You'll inherit a partially-formed team and hire the rest of it, while establishing the plays, frameworks, and operating rhythms that make GSI success repeatable and scalable. GSIs are highly matrixed organizations with multiple practices, service lines, geographies, and stakeholder groups, and success requires influence without formal authority at every level. Your team will run Claude Center of Excellence builds, Train-the-Trainer programs, and multi-practice rollouts — and you'll be the person who directs what works at one partner into a methodology that works at all of them.

You'll be instrumental in defining how Anthropic scales Customer Success through partners, not just to them.
