Responsibilities

  • Own a portfolio of Brazilian SMB customers across their entire lifecycle with fonio
  • Spend most of your time in calls and meetings with customers — building relationships, setting up AI agents, surfacing value, and keeping them engaged
  • Run regular check-ins and trigger proactive calls based on usage signals (low engagement, expansion opportunities, setup friction, etc.)
  • Work with a ready-made pipeline and clear playbooks — with room to test your own initiatives and ideas to make them better
  • Maximize the value generated from each customer in your portfolio
  • Support customers in setting up their AI assistant and coordinate appointments with our developers for more complex setups
  • Own the churn within your cohort — spot risks early and act on them
  • Work autonomously in HubSpot to manage your activity

Qualifications

  • 2–5 years of experience in Customer Success, Account Management, Sales, or a comparable client-facing role - ideally in SaaS / B2B
  • Native or C2 Brazilian Portuguese, strong English skills
  • Structured, autonomous, and results-driven
  • You build trust with customers easily — by phone, video, and in person
  • You take initiative, test, iterate — and you don't wait to be told what to do
  • Comfortable with a CRM (ideally HubSpot) and a data-driven approach to customer success
  • Ideally a strong technical understanding — comfortable reading API documentation and error logs to troubleshoot customer setup issues independently
  • An affinity for tech / AI products is a real plus
