- Stay ahead of the LLM landscape and educate customers on emerging capabilities and providers.
- Navigate technical discussions with engineering teams and strategic conversations with business stakeholders, including C-level executives.
- Build the CS foundation from scratch—define strategy, metrics, customer segmentation, and scalable playbooks for onboarding, adoption, expansion, and renewals.
- Set up the CS tech stack and operational workflows, including establishing early warning systems and health scoring.
- Partner with Sales on account transitions and expansion plays; collaborate with Product and Engineering to represent customer feedback and influence roadmap.

What We're Looking For
- 5+ years in Customer Success with experience building or scaling a CS function.
- Strong retention and expansion track record.
