Manage scaled and mid-market B2B SaaS customers across onboarding, adoption, retention, and expansion. Design scalable customer success programs including webinars, office hours, email, and in-app engagement. Balance one-to-many programs with strategic customer interactions, identify product improvements, and collaborate with product, marketing, sales, and management. The role requires building customer relationships, simplifying technical concepts, and determining when human support versus tech-touch or self-service engagement is most effective.
