The Role
You’ll play a key role in building and owning a modern frontend application within a multi-app monorepo architecture, contributing to highly interactive, data-intensive user experiences.
This is a hands-on role with real ownership, where you’ll take responsibility for a defined application and drive it from development through to production and optimisation.

* Drive best practices in testing, code quality, and architecture
* Contribute to technical decisions and frontend standards
Tech Environment
* React + TypeScript (core stack)
* Next.js / Vite
* tRPC (type-safe APIs)
* Testing: Playwright, Vitest
What They’re Looking For
* Strong experience building production-grade frontend applications (5+ years)
* Deep expertise in React and modern SPA architecture
* Experience working in monorepos or multi-application environments
* Proven ability to own features or applications end-to-end
* Strong product mindset and ability to work cross-functionally
* Comfortable balancing performance, scalability, and maintainability
Nice to Have:

Why Join
* High ownership role — own a frontend app within a larger platform
* Work on technically challenging, data-heavy applications
* Strong engineering culture with modern tools and practices
* Clear scope for growth into Staff / Lead territory
