About the role

Key responsibilities & impact

Build the frontend experiences that drive self-serve conversion: upgrade modals, plan comparison views, usage limit messaging, gating experiences, and in-product CTAs
Own the frontend side of the growth experimentation stack including implementing feature flags, building A/B test variants, instrumenting events for analytics
Build the in-product experiences that help new and existing customers hit activation milestones faster: guided flows, tooltips, checklists, contextual nudges, and feature education moments
Ensure clean, reliable event tracking across the growth surfaces you build so the team can measure activation, conversion, and feature adoption accurately
Contribute to core product work when priorities call for it

Requirements

What you’ll need

2-4 years of professional full stack engineering experience with a frontend emphasis, primarily in React with backend experience in Node.js, Python, or similar
Experience building UI that sits in the critical path of user conversion or monetization (upgrade flows, checkout, onboarding, paywalls, or similar)
Hands-on experience with feature flagging and A/B testing infrastructure, whether through third-party tools (LaunchDarkly, Statsig, Optimizely) or custom-built systems
Comfort with analytics instrumentation and event tracking (Segment, Amplitude, Mixpanel, or similar)
Experience using AI tools (Cursor, Claude, Copilot, or similar) as a core part of your development workflow, not just occasionally
Ability to move fast and ship iteratively without sacrificing code quality in the areas that matter
Strong collaboration skills, especially working in a tight loop with product and using data to inform what you build next.
