Requirements

  • Solid experience with Next.js framework and its ecosystem (SSR, SSG, ISR)
  • Proficient in TypeScript for scalable, type-safe codebases
  • Deep knowledge of front-end engineering practices: state management, code splitting, bundle optimisation
  • Strong testing and debugging with Playwright, Jest, Cypress, or similar
  • Proven mentoring and cross-functional collaboration delivering user-centric software
  • Strong understanding of design systems and component libraries, partnering with UX/UI
  • Track record of technical leadership guiding delivery across multi-environment projects
  • Experience shaping solutions during discovery and advising on technical feasibility
  • Experience with Git and modern branching strategies, including conflict resolution and peer PR reviews
  • Active UK Security Check (SC) to start, or eligible for SC with required residency
  • Candidates must be able to demonstrate a pre-existing right to work and travel within the UK

Nice to have

  • Cloud-native delivery on AWS or Azure, serverless or containers
  • GOV.UK Design System and Service Standard experience
  • Storybook ownership for UI documentation and visual review
  • Figma for collaboration and Mural for workshops
