Frontend Engineer, Web Funnels

Role overview Build and improve the web journey that takes prospective subscribers from an ad through landing pages, onboarding quizzes and checkout. You’ll turn growth team hypotheses into production experiences quickly, help decide what to test, and use results to guide the next iteration. The role is a three-month contract, with the possibility of extension or conversion to a permanent position.

Responsibilities - Build and ship web funnels end to end, including landing pages, quizzes, paywalls, checkout and upsell flows. - Create and launch A/B test variants, review their results and use the findings to plan follow-up experiments. - Set up analytics and attribution, including events, advertising pixels and server-side tracking. - Integrate billing providers, subscriptions, offers and coupons into the purchase experience. - Keep pages fast, responsive and reliable across mobile devices, browsers and countries. - Suggest funnel improvements based on user journeys and performance data.

Requirements - 2–5 years of professional frontend engineering experience, with production experience using React and Next.js. - Experience building conversion funnels, landing pages or checkout flows for a consumer subscription product, and explaining what affected conversion. - Strong HTML, CSS, JavaScript and TypeScript skills, including responsive, mobile-first implementation. - Experience with A/B testing and analytics tools such as Amplitude or GA4, plus Meta and Google pixels or conversion APIs. - Ability to deliver quickly while maintaining a polished, reliable experience across phones. - Practical experience with AI coding assistants and a clear understanding of where they help. - Fluent English.

Nice to have - Payment and subscription integrations such as Stripe, Chargebee or PayPal. - Web-to-app journeys, deep links, or handing a purchase from the web to an app. - Backend experience with Node.js, APIs or edge functions. - Familiarity with funnel-building tools and when a custom implementation is preferable.

Benefits and work setup - Fully remote, with availability to work CET hours; flexible schedule and generous vacation policy. - Access to current AI coding assistants and the opportunity to work on consumer-facing applied AI products.
