Junior Frontend Developer (React, TypeScript, Shopify)

About the Product You'll join the team behind an AI size and fit product for fashion brands. Its size advisor combines custom algorithms, product data and shopper preferences to recommend the right size, so retailers sell more and deal with fewer returns. Well-known luxury fashion brands use it on their online stores, and merchants of every size install it through our Shopify app.

We're now building virtual try-on as well. We're a small team spread across the UK, Italy, Germany and Ukraine, so you'll work directly with our CTO, our designer and our product lead. The Role We're looking for a strong junior frontend developer who's ready to take a task from ticket to release.

Most of your time will go into our Shopify app, which merchants use inside their Shopify admin to set up size charts and configure the size advisor. You'll also work on requests from our brand clients for the size advisor widget that runs on their product pages, and you may help with virtual try-on as it develops. You'll plan your work in Linear, open pull requests that a teammate reviews, and use AI coding tools every day.

We use Claude Code a lot, and we expect you to understand every line it writes for you. What You'll Do Build new features in our Shopify app, such as size chart creation and editing, merchant onboarding, recommendation settings and dashboards. Fix bugs and work through the backlog, keeping the app in line with Shopify's Polaris design system and Built for Shopify guidelines.
