Remote Shopify Front-End Developer - Freelance to Full-Time

Catalyzed, a Rotterdam e-commerce agency, helps Shopify brands scale with data-driven strategy and tight execution. You turn Figma designs into fast, testable front-ends and theme changes, collaborating with CRO specialists and a UX designer to ship measurable results.

Fully remote, flexible hours. Start freelance and grow into a full-time role, building reusable components and contributing to real traffic A/B tests across client stores.

Build A/B test variants and theme changes from Figma: product pages, collections, carts and landing pages. Ship clean, fast, mobile-first front-end that works in every browser. You QA your own work before anyone else sees it. Set up variants in the testing tool and check the tracking, so every result can be trusted. Tell the team what's buildable, and how to build it faster or better. Write code the next test can build on: reusable sections and snippets, not one-off hacks. At least 3 years of front-end development with Shopify stores in production. Strong in Liquid, JavaScript, HTML and CSS, and Online Store 2.0 themes (sections, blocks, metafields). You build from Figma accurately, mobile first, and you care about page speed. Git and Shopify CLI are part of your daily work. AI-savvy: AI is part of how you code, test and QA, and you still review every line yourself. Plus: Shopify Plus and checkout extensibility, A/B testing tools (Shogun, Intelligems, Convert, VWO), Klaviyo, Rebuy, GA4 and GTM. You work independently and own your work from handover to live. 100% remote Flexible hours Remote-friendly Potential full-time transition Collaborative team
