Director, Customer Success - Enterprise

Director Of Enterprise Customer Success Management

As a strategic leader of the Customer Success organization, our job is to solve for both the customer experience and our employee experience. We do this by creating trust with our customers and our team through humility and open-mindedness, and by giving the team a strong sense of purpose as part of the Customer Success organization. Our job is to empower the team by giving them the clear vision, direction, and support they need to grow and help our customers own their growth.

As Director of Enterprise CSMs, you'll lead a team of managers to deliver the Enterprise CSM team's vision: a world-class customer experience. You'll own the growth and development of your team, drive efficiency through improved process and operationalized plans, act as an escalation point for customer and team issues, and lead your team to develop and execute the strategies needed to reach Klaviyo's business goals.

You'll report to the Vice President of Customer Success and focus on refining the Enterprise customer experience, collaborating closely with Onboarding, Sales, Finance, Product, and Marketing leaders to build out the upmarket customer engagement model. You'll fully own the Enterprise customer experience post-onboarding, with success measured against retention and cross-sell numbers for the North American Enterprise CSM team.

You're highly collaborative and innovative, with a track record of relentless and effective execution. You're results-driven, you ensure data informs every decision, and you're excited to tackle some of Klaviyo's most challenging opportunities for improving the customer experience.
