Fullstack Engineer

We're looking for a senior product engineer first someone who picks up a feature, designs it end-to-end, writes the code, and ships it to production with tests that catch real regressions. You'll work across our Next.js front-end and NestJS back-end, collaborating closely with Product, Design, Mobile, and BI.

This is a hands-on role for someone who likes to own things from idea to production and who uses modern AI coding tools as a natural part of their workflow.

What you'll do

• Build and maintain scalable backend services using Node.js, NestJS, TypeScript, Prisma, and PostgreSQL
• Develop clean, performant frontend applications using Next.js (App Router, RSC) and React
• Design and optimise APIs consumed by mobile apps (Flutter) and internal tools
• Own database design, migrations, indexing, and performance optimisation across a large Prisma schema
• Implement secure authentication and authorisation flows (JWT, OAuth) with GDPR awareness
• Write high-quality, testable code unit, integration, and E2E tests that catch real regressions, not coverage filler
• Deploy and operate services on AWS (EKS, Docker, CI/CD, Helm)
• Write clear technical documentation: RFCs when proposing changes, postmortems when regressions slip through

• 3 5 years shipping production full-stack TypeScript; you've led non-trivial features end-to-end
• Deep knowledge of Next.js App Router, React Server Components, React 19 runtime, route handlers, middleware
• Deep NestJS + Prisma controllers, services, guards, interceptors, DTOs with class-validators are second nature
• Strong TypeScript you use the type system to prevent bugs
• Solid testing instinct you write tests that catch real regressions, not coverage theatre
• Fluency with modern AI coding tools (Claude Code, Cursor, Copilot, or similar) you use them daily and can compose AI-generated code into something coherent and maintainable
• Experience designing and maintaining REST APIs
• Production experience on AWS; familiarity with Docker, Kubernetes (EKS), and CI/CD pipelines
• Comfortable in a regulated environment (GDPR, data privacy) or demonstrably ready to learn
• Good written communication: clean RFCs, clear postmortems, no ambiguity
