Senior Customer Success Manager

Luma AI Luma AI · AI Frontier · New York, NY · Sales

Senior Customer Success Manager role at Luma AI, a multimodal AI company. The role focuses on owning a portfolio of enterprise accounts, driving adoption, retention, and expansion. Responsibilities include building executive relationships, running the full enterprise CS motion, leading customer success initiatives, mentoring junior CSMs, and serving as a voice of the customer to Product, Engineering, and GTM leadership. The ideal candidate has 5-8 years of experience in client-facing roles, strong systems thinking, and comfort operating with autonomy in a fast-evolving environment. Experience in high-growth startups, particularly in AI or creative tech, is a plus.

What you'd actually do

  1. Own a portfolio of Luma's enterprise accounts, driving adoption, retention, and expansion with minimal oversight.
  2. Build and maintain executive-level relationships within your accounts — operating as a strategic advisor, not just a point of contact.
  3. Run the full enterprise CS motion: structured onboarding, success planning, executive business reviews, renewal management, and expansion identification.
  4. Lead scoped customer success initiatives end-to-end — executive business review programs, customer health frameworks, onboarding journeys for new customer segments, technical enablement programs.
  5. Informally mentor and coach CSMs through account reviews, customer escalations, and day-to-day craft — modeling what great looks like without formal management accountability.
