Full Job Description


Requirements

Own Your Book of Business
  • Manage a portfolio of B2B accounts, serving as the primary point of contact and trusted advisor throughout the customer lifecycle.
  • Build and maintain strong executive and champion-level relationships within each account.
  • Deliver regular business reviews that tie product usage to customer outcomes and business value.

Drive Retention & Flag Churn Risk
  • Monitor account health signals - usage trends, support tickets, stakeholder changes - and proactively intervene before risk escalates.
  • Maintain an accurate, up-to-date view of renewal likelihood across your portfolio at all times.
  • Develop and execute mitigation plans for at-risk accounts in collaboration with sales and leadership.

Expand Revenue
  • Identify organic expansion opportunities - new use cases, additional seats, or adjacent products - and partner closely with Account Executives to execute upsell and cross-sell motions.
  • Build multi-threaded relationships within accounts to reduce single-point-of-failure risk and uncover new growth opportunities.

Influence Product
  • Aggregate and synthesize customer feedback into clear, prioritized product insights for the Product and Engineering teams.
  • Act as a customer advocate internally - bring the voice of the customer into roadmap discussions, QBRs, and sprint reviews.
  • Close the loop with customers when their feedback has influenced product decisions.


What We're Looking For
  • Experience in customer success, account management, or a related post-sales role in B2B SaaS or technology - ideally with some exposure to an early-stage or high-growth environment.
  • A bias toward action: you don't wait for perfect information to move, you close the loop fast, and you iterate without being asked.
  • Scrappy and resourceful - when there's no playbook, you write one. When the tool doesn't exist, you find a workaround. You build the plane while flying it.
  • Exceptional attention to detail: your CRM is always current, your follow-ups never slip, and your customers notice.
  • Comfortable with ambiguity and change - our product, processes, and priorities will evolve, and you'll evolve with them rather than waiting for things to settle.
  • Strong analytical mindset - you're comfortable digging into usage data, building account health models, and presenting findings clearly.
  • Clear, confident communicator - written and verbal - who can engage comfortably at the C-suite level.
  • Natural collaborator who works effectively across Sales, Product, Support, and Engineering with low ego and high output.


We hire remotely across US time zones.

Benefits
  • Medical, dental, and vision (US)
  • 401k (US)
