We're looking for a Senior Fullstack Developer to join our team and take ownership of building, optimizing, and scaling high-performing e-commerce experiences. You'll work across the fullstack - from Shopify storefront UX to backend integrations and payment systems with a direct impact on conversion, reliability, and global reach.

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

Yêu cầu công việc

• 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
