In this role, you will

  • Build and improve UI/UX across Shopify storefronts with a mobile-first approach, serving over 90% mobile traffic
  • Manage and scale multi-currency and multi-language storefront setups
  • Develop new features that improve store performance, subscription UX, and overall conversion rates
  • Run A/B tests and implement tracking to continuously refine user interactions
  • Maintain and extend payment gateway integrations (Apple Pay, Google Pay, PayPal, Stripe, Klarna, and more)
  • Own backend reliability through robust monitoring, error tracking, and webhook event logging
  • Enhance internal Shopify Admin tooling for a smoother operational experience

    • What you will bring

  • 8+ years of software development experience, with strong hands-on TypeScript and Node.js

  • Deep JavaScript fundamentals - async execution order, what your framework actually does under the hood.

  • Strong general fundamentals of modern web applications - how apps render in the browser, rendering strategies, how to make the customer experience smooth and fast, and how frontend, backend, and multiple systems communicate — especially in a global e-commerce context

  • Production experience in React or Vue (and Next.js or Nuxt) - depth in one matters more than shallow exposure to both; you should be able to explain what your framework does under the hood

  • Familiarity with AWS - you can reason about how an application is deployed and served (compute, CDN, storage, secrets); experience on another cloud and mapping the concepts across is just as good

  • Daily, hands-on use of Git, CI/CD pipelines, and agile workflows.

  • Be the driver, not a passive coder - you propose solutions, sketch the architecture, and challenge requirements that don't make sense.

  • Strong written and spoken English - the role involves daily collaboration with international stakeholders; clear, structured, to-the-point communication in technical discussions and async writing

  • Active engagement in team ceremonies and confident contribution to technical discussions

  • Willingness and ability to learn the Shopify ecosystem - you don't need Shopify experience on day one, but you must be genuinely curious and motivated to build it

    • Nice to have

  • Shopify Functions, Shopify APIs, or Checkout UI Extensions experience

  • End-to-end testing exposure (Playwright, Cypress)

  • A/B testing and analytics/tracking tools

  • Multi-currency / multilingual storefront setups

  • Payment gateway integration experience

  • Deep cross-browser and cross-platform troubleshooting
