Senior Full Stack Engineer - Growth & Monetisation

Role overview

Sydney · Full-time · On-site/hybrid 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 - Build and own monetisation: plans, paywalls, subscriptions, credit and usage metering, auto top-up, access control and revenue share. - Own onboarding and activation end to end — signup, first task, first genuine result — and the experiments that improve them. - Build the analytics and experimentation foundations: events, funnels, attribution and A/B tests, so decisions come from data rather than opinion. - Work directly with payment providers and their failure modes: declines, webhooks, disputes and platform-specific quirks. WHAT WE'RE LOOKING FOR - 3–5+ years full-stack with shipped experience in payments, subscriptions or growth surfaces. - TypeScript/React and Python, plus SQL fluency — you can answer your own funnel question. - Comfort owning a metric, not only a backlog.
