Self-serve consumers and enterprise seats run through the same billing and activation paths. This role owns the money and the funnel.

What You'll Do

n

n
Build and own monetisation: plans, paywalls, subscriptions, credit and usage metering, auto top-up, access control and revenue share.
n
Own onboarding and activation end to end — signup, first task, first genuine result — and the experiments that improve them.
n
Build the analytics and experimentation foundations: events, funnels, attribution and A/B tests, so decisions come from data rather than opinion.
n
Work directly with payment providers and their failure modes: declines, webhooks, disputes and platform-specific quirks.

What We're Looking For

n

n
3–5+ years full-stack with shipped experience in payments, subscriptions or growth surfaces.
n
TypeScript/React and Python, plus SQL fluency — you can answer your own funnel question.
n
Comfort owning a metric, not only a backlog.
