Shopify Front-end Developer - freelance to full-time, 100% remote About the role
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.
Responsibilities
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.
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.
Requirements
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.
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 we offer
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.
