About the job
A seed-stage software company with a large engineer user base and a roster of enterprise accounts is hiring its first leader for everything that happens after the sale. The person in this seat will work in a hands-on way, serving customers directly while designing the systems that let the team grow later, and will sit close to the founders.
Your focus
Guide enterprise customers from kickoff through ongoing reviews, renewals and account growth
Work support tickets yourself and resolve them, then build AI-driven agents that sort and automate repetitive requests
Create the post-sales playbooks, account health scoring and repeatable processes the company currently lacks
Grow revenue within existing accounts through expansion and upsell while keeping relationships consultative and trusted
Decide when to add specialist hires, for instance technical account managers or engineers embedded with customers, and later recruit and lead them
About you
Roughly five to ten years in customer success at an early-stage B2B SaaS company with a lean team
Has launched a post-sales team from nothing, including onboarding flows, playbooks and health scoring
Personally carried retention, renewal and expansion targets and can speak to the retention and expansion figures you delivered
Comfortable building automation or AI agents to streamline support work
Prefers doing the work over managing an existing team
Familiar with a CRM or CS platform such as Salesforce or Gainsight; experience selling technical products to enterprises is a plus
Hybrid in the San Francisco Bay Area, with regular in-office days. Unable to consider candidates who need visa sponsorship or a visa transfer.
