Shopify Front-end Developer - freelance to full-time, 100% remote

Shopify Front-end Developer | Freelance to full-time | 100% Remote
Want the code you ship judged by conversion rate?

Catalyzed is the Rotterdam e-commerce agency that helps Shopify brands scale with sharp strategy and tight execution. We test everything. Every design goes live as an A/B test against the original, with real traffic, and the winner stays. You're the one who makes it live.

As Shopify Front-end Developer you turn Figma designs into fast, pixel-perfect test variants and theme changes. You work with heavy hitters: CRO specialists who know what to test and a UX designer who knows how it should look. Spotted a good idea? Live tomorrow. Built by you.

Fully remote, flexible hours. Let's catalyze. Together.

What will your day-to-day look like?

• 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.

Your goal: tests live fast, bug-free, and results we can trust.

You bring the code. And the care for every pixel and millisecond.

• 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.

Fluent English is required. Dutch is a plus.

What do we bring to the table?

• 🌍 100% remote. Work where you work best, on hours you plan yourself.
• 🧪 See what your code earns. Every variant you build runs as an A/B test on real traffic. Moving the reviews right under the add-to-cart button lifted add-to-cart by 25.87%. Small builds, real numbers, and you see your own.
• 🛍️ Brands that want to scale. Cloudpillo, plnktn, Boombrush, Somnox: real products, real customers, real stakes.
• 🧠 Heavy hitters. CRO specialists and designers who hand over clear briefs and clean Figma files.
• 🚀 Start freelance, grow into the team. Show us your work for a few weeks; if it clicks on both sides, we go full-time.
