Senior Fullstack Engineer (Frontend focus, Next.js/Node.js/AWS)

You will own the frontend of a high-traffic headless storefront and the Node.js services behind it, serving customers across Europe, Latin America and APAC. Page speed here is not a nice-to-have, it maps directly to conversion, so your work centres on rendering strategy, caching and delivery at the edge. You will work day to day with the client's engineering team in Europe, contributing to architecture decisions rather than just implementing tickets.

Lead the design and development of a multi-market storefront in Next.js and TypeScript, covering catalog, product pages, cart and checkout flows.

Choose and justify the right rendering strategy per surface (static, incremental, server-rendered, client-side) based on traffic patterns and freshness needs.

Design the caching layer end to end, from CDN and edge through to browser, including invalidation when product, price or inventory data changes.

Own the performance budget and optimise across regions, from bundle size and hydration cost through to time to first byte.

Build and maintain the orchestration layer between the storefront and commerce services using Node.js with REST or GraphQL.

Handle multi-currency and multilingual storefront experiences so each market gets the right catalog, language and pricing.

Implement and iterate on payment and checkout flows, working with gateways such as Stripe, PayPal, Klarna, Apple Pay and Google Pay.

Support A/B testing and analytics tracking so product decisions are backed by data.

Guarantee test coverage with unit, integration and end-to-end testing, and keep CI/CD pipelines healthy.

Support observability and operational excellence with proper logging, monitoring and rollback procedures, leveraging AWS where applicable.

Guide and mentor mid-level engineers, and share context with both the Gradion team and the client's engineers.

Experiment with AI developer tools (Cursor, Claude, Copilot).
