About [REDACTED]

At [REDACTED], we move fast, think big, and drive results. As a global leader in data-driven performance marketing, we combine high-impact user experiences with sharp creative to scale brands across continents.

Our culture is built on our Triple E philosophy: Energy, Entrepreneurship, and Expertise. We operate with a vibrant, agile startup mentality and no corporate red tape. If you have an idea, you test it. If you see a friction point in a user journey, you fix it. We are expanding our Amsterdam headquarters and looking for a designer who ships: a UX/UI Designer who takes their own work from Figma all the way to a live Next.js production site.

The Role

This is not a classic handoff role. You design the experience and you publish it. Your Figma file becomes a live page because you built it, in Next.js, often the same week.

Day to day you will design and ship high-converting landing pages, onboarding quiz funnels, and lifecycle emails; manage the websites they live on; and keep improving them with CRO experiments. AI-assisted building ("vibe coding" with tools like Claude Code, Cursor, or v0) is core to how this role works, not a side experiment. You will touch several verticals and own things end to end: design, build, CMS, tracking, iteration.

What You’ll Do

• Design and publish, yourself: Map user journeys, wireframe, design high-fidelity screens in Figma, then build and deploy them in Next.js. No waiting on a dev sprint.
• Own the website stack: Manage our sites end to end. Set up and maintain a headless CMS so the team can edit content without touching code, and keep deployments, domains, and tracking healthy.
• Run optimisations and CRO: Analyze user behavior and funnel data, form hypotheses, ship A/B tests, and iterate based on real performance metrics.
• Work across verticals: Landing pages are the core, but you will also design and build onboarding quiz flows and email campaigns, so the same brain covers the whole funnel.
• Frontrun with AI: Actively use AI design and coding tools to collapse the distance between idea and live page. Prototype in hours, ship in days.

Who You Are

• The sweet-spot experienced: 2–4 years as a UX/UI, product, or web designer, with shipped web work to show for it (conversion-driven e-commerce or startup experience is a major plus).
• Master of Figma: Clean component-based design systems, auto-layout, interactive prototypes.
• You publish, not just hand off: Comfortable enough with Next.js, React, and Tailwind (with AI tools doing the heavy lifting) to take your own design live in production. You don’t need to be a senior engineer. You need to ship.
• Infrastructure doesn’t scare you: Hosting and deployments (e.g. Vercel), domains and DNS, analytics and tracking scripts, and headless CMS setup (Sanity, Contentful, Payload, or similar) are things you can figure out and own.
• Data-informed and AI-native: You design what works, not just what looks good. You read funnel data, session recordings, and test results, and you turn them into the next iteration.
• Thrives in a dynamic culture: Rapid A/B testing, quick iterations, shifting priorities based on performace data. You enjoy that.
• Portfolio driven: Live URLs beat static mocks. We want to see things you designed AND built.

To Apply

Send us your CV and a portfolio with live links: pages you designed and shipped yourself. Tell us briefly what you built, what you would improve, and which tools you used to get it live.
