Manager, Customer Success

GlossGenius is the AI-powered system behind the world's most meaningful appointments, helping 120,000+ service businesses earn more revenue and free up time for the work they love. Our agentic workforce gets more clients in the door, grows profit per appointment, and keeps clients coming back — doing the jobs owners never had time for and couldn't justify hiring to fill. Businesses on GlossGenius process billions in annual payment volume, and see 65% more revenue using GlossGenius Payments by growing ticket size, rebooking clients at checkout, and saving on processing fees.

GlossGenius's customer base is growing fast, and our post-sales experience will be a real competitive differentiator.  In this role, you'll lead the team of Onboarding Specialists responsible for getting high-revenue customers live on the platform, and you'll help to architect our broader Customer Success motion as we scale. You'll define what great looks like, from team structure to engagement strategy to the AI-powered workflows that make the whole operation run more effectively. This is a player-coach role that requires strong management instincts and a builder's orientation: you'll need to be in the work while simultaneously designing the system around it.

You will report to the Director of Revenue Operations. You must be commutable to our NYC headquarters and will operate in an in-person environment. We default to being in-office 3–4 days per week with required attendance on Tuesdays and Thursdays.
