Job descriptions & requirements
Responsibilities:
- Build and ship features in our React web app: dashboards, forms, lists, and authenticated flows used by property managers and residents.
- Work with the backend team to integrate APIs cleanly, with consistent error handling and a clear contract between client and server.
- Own the design system: maintain shared components, keep styling consistent, support light and dark mode, and make sure new pages reuse what already exists.
- Build for the devices our users have: mid-tier Android over slow networks. Performance, bundle size, and accessibility are part of the job.
- Handle auth, sessions, and role-based access so the UI reflects what the user is actually allowed to do at any moment.
- Manage forms, lists, and pagination at scale without re-inventing the same patterns on every page.
- Write tests for the things that matter: critical user flows, auth, payments, and reusable utilities.
- Keep the app reliable in production: error boundaries, sensible loading and empty states, and graceful failure when the network is unstable.
Requirements:
- 4 years of professional React experience shipping non-trivial web apps with TypeScript.
- Strong TypeScript: generics, narrowing, and writing types that catch bugs at the boundary between client and server.
- Tailwind CSS at a real scale, including dark mode and responsive layouts.
- React Router 6 with route guards and data loading.
- Comfort with Vite (or similar modern build tooling), code splitting, lazy routes, and PWA basics.
- Solid judgment on state and data fetching: when to use Context, when to lift state, and when to introduce a server cache.
- Habit of reading API contracts (or the actual handler code) before wiring a feature, rather than guessing wire shape.
- Testing habit with Vitest or Jest and React Testing Library.
- Accessibility awareness: semantic HTML, keyboard navigation, contrast.
- Ownership: you take a problem from a ticket to a tested fix and a clear note for the team, not just a merged PR.
- Strong written and spoken communication in a small, fast-moving team.
Preferred Qualifications:
- Complex forms and modal flows in production.
- Charting libraries (Recharts or similar) and data-dense dashboards.
- PWA and push notifications shipped in production.
- Design system or component library ownership in a prior role.
- Performance work: Lighthouse, bundle analysis, and web vitals.
- Multi-tenant or B2B products where permissions and context add complexity.
- Experience working from OpenAPI specs or generated types with a backend team.
- Early-stage or greenfield experience where speed and durability had to be balanced.
