  • 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

  • 5+ years of experience in software development, with strong hands-on skills in TypeScript, Node.js, React or Vue.js, plus familiarity with Liquid or similar templating engines, and working exposure to AWS

  • Strong fundamentals in how modern web applications work: browser rendering, frontend/backend communication, and delivering fast, smooth customer experiences - especially in a global e-commerce context

  • Experience with A/B testing, analytics/tracking tools, and frontend performance optimization

  • Knowledge of multi-currency and multilingual storefront setups

  • Familiarity with Git, CI/CD pipelines, and agile workflows

  • Deep understanding of cross-browser and cross-platform issues, with practical solutions
