We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world. - ESOP Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together. - Tech Allowance Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work. - Health Benefits Supabase covers 100% of health insurance for employees and 80% for dependents, wherever you are. Your wellbeing and your family’s health are important to us. - Annual Off-Sites Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun.

We built the world's first consumer AI app. Two million people showed up in two months. 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. People become more social, more confident, more themselves. Not in theory. In their actual lives. Every major AI company talks about their mission for humanity. None of them has ever clearly said what they're trying to do for a single person. We will. We want to help you flourish in real life. Not become a better version of yourself, just more yourself. Strong relationships. Better health. Meaning. Momentum. 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. That sends you a poem, just because. The goal is conversations that lead somewhere real. Maybe it's a text you send to a long lost friend. A hobby you pick up again. A moment you show up for yourself. Everyone else is building AI that thinks. We're building AI that cares. Frontend Engineer, Web Funnels About this role Most people who subscribe to Replika on the web come through a funnel: an ad, a landing page, a quiz, a paywall. 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. This is a hands-on build role. 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. Speed matters, and so does the feel. For a lot of people, these pages are the first time they meet Replika. 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. Take a hypothesis, build the variants, launch, read the result, and move to the next one. 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. Bring ideas. 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. Rock-solid web fundamentals: 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. Fast without being sloppy. 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 experience: Stripe, Chargebee, PayPal or similar. Web-to-app funnels: deep links and handing a buyer over to the app. Hands-on backend chops: Node.js, APIs, edge functions. You've used funnel builders and know when a custom build beats them. What You’ll Get Unlimited access to the latest AI coding assistants. Flexible job schedule and generous vacation policy. Direct impact on millions of worldwide users within months. Push the boundaries of applied AI in a consumer setting. Fully remote, able to work CET hours.

ABOUT WHITE CIRCLE White Circle http://whitecircle.com is an AI Safety company building the safety, reliability, and optimization layer for AI systems.

This is a high-impact role suited for someone who decides with data, not intuition. Unmeasured prompt changes, untraced failures, and model swaps without benchmarks are not acceptable.
