Be a Strategic Partner to Product, Sales, and Leadership

  • Collaborate closely with Sales on account planning and pre-to-post handoffs
  • Bring a commercial lens to everything - always thinking about how success drives revenue

What Our Ideal Candidate Looks Like

  • 8+ years in Customer Success or Account Management, with a clear track record of owning revenue (renewals + expansion)
  • Enterprise experience - you've navigated complex orgs, long sales cycles, and strategic conversations
