Job Description

The Frontend Team builds the embeddable checkout, authentication and express-checkout web components behind SCAYLE’s Checkout as a Service which is our in-house eCommerce infrastructure licensed to online retailers. Tenant storefronts integrate them as a drop-in script, and the components own everything the customer sees from entering the checkout to order confirmation: authentication, addresses, payment selection and order placement, across many shops, countries and payment providers.

• Architecting and building modular checkout UI components in TypeScript and React, managing state and side effects with Redux Toolkit and redux-saga
• Developing payment provider integrations (e.g., Klarna, PayPal, Apple Pay), including widget and redirect flows
• Owning storefront integration contracts for multi-tenant setups, including embeddable web components, host events, and tracking
• Optimizing Core Web Vitals, loading speeds, and rendering performance to drive conversion rates and elevate user experience
• Monitoring and resolving production issues across tenant shops using observability tools like Datadog
• Translating complex checkout requirements into scalable solutions while ensuring WCAG accessibility, responsive design, and cross-browser compatibility
• Collaborating cross-functionally with Product, UX, Backend, and QA teams in daily agile workflows to ship features like one-page or multi-step checkout flows
• Driving engineering standards through thorough code reviews, architectural discussions, and technical refactoring initiatives
• Expanding core platform capabilities (e.g., for the SCAYLE checkout ecosystem) to enable client customization through injectable content
