Guide customers on model selection, routing strategies, and cost/quality/performance tradeoffs.
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 CS foundation from scratch—define strategy, metrics (NRR, GRR, CSAT), customer segmentation, and scalable playbooks for onboarding, adoption, expansion, and renewals.
Set up the CS tech stack and operational workflows. Establish 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.
Advocate for customer needs with Product and Engineering teams and influence the roadmap based on customer insights.
Qualifications:
5+ years in Customer Success with experience building or scaling a CS function.
