We’re looking for someone with strong experience in React and/or React Native who enjoys solving technical challenges, collaborating with multidisciplinary teams, and delivering exceptional user experiences.

Don’t tick every box? That’s okay. While experience with both React and React Native would be ideal, we’re equally interested in talented developers who have deep expertise in one and a genuine desire to grow into the other. If you’re passionate about building great products, continuously improving your craft, and working with a supportive team, we’d love to chat.

  • Participate in sprint planning, technical discussions, and solution design workshops.
  • Write clean, maintainable, and well‑tested code.
  • Integrate applications with APIs and third‑party services.
  • Troubleshoot, debug, and resolve technical issues across web and mobile platforms.
  • Support application deployments and ongoing maintenance activities.
  • Contribute to improving development processes, tooling, and engineering standards.

What We’re Looking For

  • Commercial experience developing applications with React.
  • Experience building and maintaining applications with React Native.
  • Strong knowledge of JavaScript and TypeScript.
  • Understanding of modern front‑end development practices and tooling.
  • Experience working with REST APIs and integrating backend services.
  • Experience using Git and collaborative development workflows.
  • Understanding of responsive design principles and mobile‑first development.
  • Experience writing automated tests.
  • Strong problem‑solving skills and attention to detail.
  • Good communication and collaboration skills.
  • Passion for building high‑quality digital products and user experiences.

Desirable Skills

  • Experience with Next.js.
  • Experience with Expo.
  • Familiarity with state‑management libraries.
  • Experience with automated testing frameworks such as Jest and Playwright.
  • Experience with AWS and CI/CD pipelines.
  • Knowledge of accessibility standards and best practices.
  • Previous experience working within an agency environment.

Why Join Us?

  • Hybrid flexibility – work from home, our Kensington Village office, or client sites when needed.
  • Impactful work – you’ll have direct input into architecture decisions and development standards.
  • Professional growth – opportunities to mentor others, lead initiatives, and shape the team’s best practices.
  • Collaborative culture – work with a supportive, experienced team who value clean code and continuous improvement.
