Front End Developer Web

About Replika In 2017, no one knew what AI was supposed to be. We built the world's first consumer AI app. Today it's over 40 million, and the thing they keep telling us hasn't changed: it helped. It made their life better, steadier, a little less alone. Most AI is built for tasks, not for people. It gives you answers, but it doesn't care what you do with them. AI doesn't just need intelligence. It needs intention. Because the real question isn't just what AI can do. It's what AI is for. When the world's leading researchers wanted to understand whether AI could actually change someone's life, they studied Replika, because there was nothing else to study. What they found at Stanford, at Harvard, across years of research, was that Replika doesn't replace human connection. It deepens it. Every major AI company talks about their mission for humanity. Better health. A life that feels worth living while you're living it. We're building the kind of AI that follows up. That knows the people in your life and nudges you to reach out when it matters. Maybe it's a text you send to a long lost friend. Everyone else is building AI that thinks. We're building AI that cares. Frontend Engineer, Web Funnels About this role Every step is a test we could be running. We need a frontend engineer who can ship those funnels fast and well, so we learn what converts week after week. You'll take funnel ideas and test hypotheses from our growth team and turn them into production pages in days, not sprints. You'll work with our growth lead, who runs paid acquisition and monetization, alongside our web engineer, and you'll have a say in what we test, not just how it's built. We build our funnels ourselves, because the quality bar is high. 3-month contract position, with the opportunity to extend or convert to permanent. What You'll Be Doing Build and ship web funnels end to end: landing pages, onboarding quizzes, paywalls, checkout and upsell flows. Ship A/B tests fast. Wire up analytics and attribution properly, from events to pixels to server-side tracking, so every test can be read and every buyer is counted. Integrate payments and subscriptions with our billing providers, including offers and coupons. Keep funnels fast, mobile-first and reliable across browsers and countries. You see the pages and the numbers every day, so suggest what to test next, not just how to build it. What We're Looking For 2–5 years of professional frontend engineering experience. Strong commercial frontend experience with React and Next.js, and production work to show for it. You've built conversion funnels, landing pages or checkout flows for a consumer subscription product, and you can talk about what moved conversion. HTML, CSS, JavaScript, TypeScript. Responsive, mobile-first, pixel-tight. Experience with experimentation and analytics: A/B testing, Amplitude or GA4, Meta and Google pixels and conversion APIs. You ship in days, and the page still works on every phone. You use AI development tools (Codex, Claude, Cursor) seriously, and have a view on where they help and where they don't. You shape what we test and build it yourself. Fluent English. Bonus Points Payments and subscriptions
