About the Role

This role owns the money and the funnel, managing billing and activation paths for both self-serve consumers and enterprise seats.

Responsibilities

  • Build and own monetization features including plans, paywalls, subscriptions, credit and usage metering, auto top-up, access control, and revenue share.
  • Own the end-to-end onboarding and activation process, including signup, first task, first genuine result, and associated experiments.
  • Build analytics and experimentation foundations such as events, funnels, attribution, and A/B tests to drive data-informed decisions.
  • Collaborate directly with payment providers, managing declines, webhooks, disputes, and platform-specific issues.

Requirements

  • 3-5+ years of full-stack experience with shipped products in payments, subscriptions, or growth surfaces.
  • Proficiency in TypeScript/React and Python.
  • SQL fluency to answer funnel-related questions independently.
  • Comfort with owning a metric, not just a backlog.
