Your role
We're looking for a detail-oriented QA Shopify Developer to own the quality of our Shopify storefronts. You'll join a mature Shopify environment with an established codebase and release process, and be responsible for making sure every change works before it reaches customers.
This is a QA-first role, but not only QA. You'll also take on Shopify development tasks, and we want you to find the manual work in our testing process and replace it with automation. There's a learning curve here, and we'll support you with structured onboarding. The most important things you bring are hands-on Shopify experience, a sharp eye, and a genuine drive to learn.
Here you’ll get to:
- Own QA for theme releases and new features before they go live
- Build and maintain test plans, checklists and regression coverage for storefront functionality
- Test across browsers and devices, including mobile, checkout flows and key conversion paths
- Test for accessibility against WCAG standards, including keyboard navigation, screen reader behaviour, colour contrast and form labelling
- Write clear, reproducible bug reports and verify fixes
- Identify repetitive manual QA work and propose and build automation to replace it
- Pick up Shopify development tickets, from content and settings changes to theme fixes and small features, taking on more as you grow
- Work within Git and pull request workflows alongside other developers
- Document testing processes so they're repeatable
About you:
- 1 to 3 years of hands-on Shopify experience at an agency or a brand running on Shopify
- A portfolio of Shopify work you can show us
- Solid understanding of Shopify themes: Liquid, sections, templates, theme settings and the Shopify admin
- Working knowledge of HTML, CSS, Liquid, JavaScript and TypeScript, plus familiarity with lightweight client-side frameworks such as Stimulus or Alpine.js
- Real QA experience: you've written test plans, run regression testing and filed bugs, and can walk us through how you approach testing a release
- Experience with at least one test automation tool, such as Playwright, Cypress or Selenium
- Experience using AI tools to automate testing or other workflows, with a project or example you can share
- Comfortable with Git and pull requests
- Highly detail-oriented, and someone who takes ownership of their work without needing to be chased
- Hands-on accessibility testing experience, with working knowledge of WCAG 2.1 AA and tools such as axe, WAVE or a screen reader
We’d love it if you also had:
- Shopify Plus experience
- CI/CD experience, for example GitHub Actions
- Visual regression testing tools
- Performance testing, for example Lighthouse
- Shopify CLI or the Shopify Admin API
