Principal React Engineer

Remote (UK) | Permanent

At a Glance

Role: Principal React Engineer

Salary: £100,000 £120,000

Location: Remote (Northern Ireland based)

Employment type: Permanent, full-time

Stack: React, TypeScript, Storybook, Jest, RTL, Cypress


The Role

This is a frontend leadership position for someone who wants to own architecture, set direction, and genuinely raise the bar across an engineering organisation. You will take control of a large-scale React ecosystem, drive best practice across multiple teams, and build experiences that matter to users.


It is a hands-on role with real strategic weight. You will work closely with Product, UX, and Backend, influence the long-term technical roadmap, and have a direct hand in how frontend engineering is done across the business.


What You'll Be Doing

  • Lead and define frontend architecture and standards across the organisation
  • Drive adoption of React and TypeScript best practice across multiple teams
  • Build and scale component libraries and design systems
  • Partner with Product and UX to deliver clean, intuitive interfaces
  • Mentor engineers and contribute to the overall capability of the team
  • Own performance, accessibility, and long-term maintainability of the frontend
  • Work closely with backend teams on API design and integration
  • Champion modern tooling, testing practices, and CI/CD
  • Contribute to the technical roadmap and broader engineering strategy


What You'll Bring

Essential

  • Strong commercial experience with React and TypeScript at scale
  • A proven track record of frontend technical leadership in a commercial environment
  • Deep understanding of state management, performance optimisation, and UI architecture
  • Experience building or working closely with design systems (Storybook or equivalent)
  • Solid knowledge of modern testing approaches: Jest, React Testing Library, Cypress
  • A genuine interest in mentoring and developing engineers around you
  • Comfortable operating across cross-functional teams, including Product and UX


Nice to Have

  • Backend or full stack exposure
  • Cloud experience, ideally AWS
  • Experience in data-heavy or complex product environments
  • Background in product-led organisations


Why Apply

This is a rare opportunity to step into a genuine Principal-level role with real ownership and real influence. The feedback from engineers placed within this team has been consistently strong, and the breadth of impact available here is not something you see in many roles at this level.


If you are a senior React engineer ready to move into or further establish yourself at Principal level, this is worth a conversation.
