[Hiring] Frontend Engineer @Replika

Role Description

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.

Qualifications

• 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.

Benefits

• 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.
