Full-Stack Engineer (Next.js / TypeScript)

Ship the storefront, the checkout and the customer dashboard on a modern Next.js codebase with real traffic behind it.

The site is Next.js 15 on the App Router with React 19, TypeScript in strict mode and Tailwind v4, deployed on AWS Amplify. Payments and fulfilment run through a gateway integration; analytics runs through several event pipelines at once.

It is a real production codebase with real constraints — a build-output ceiling, a CDN that caches harder than you would like, and 650-odd pages that all have to keep ranking. We write guards for the mistakes we have already made rather than a document asking people not to repeat them.

Hours: Full-time, asynchronous. Some overlap with European hours for reviews.

This role is 100% remote.

What you will do

• Build and maintain the marketing pages, the checkout funnel and the customer dashboard.
• Work across the stack: server components, API routes, third-party integrations, and the CSS that holds it together.
• Keep performance and Core Web Vitals honest on mobile, where our traffic actually is.
• Write the build-time checks that stop a class of bug coming back.
• Review other people's changes carefully, including ours.

What we are looking for

• Strong TypeScript and React, and real experience with a modern Next.js app — App Router, server and client components, and when each is right.
• You can reason about a rendering or caching problem rather than shotgunning changes at it.
• Comfortable with CSS at a level beyond utility classes.
• You test what you ship, and you say so plainly when something is not working.

Nice to have

• Experience with a payment gateway integration or webhook-driven fulfilment.
• Familiarity with AWS Amplify, Lambda or CloudFront behaviour.
• You have cared about technical SEO on a large site before.
