Required
3+ years building production web applications, with strong ownership of features from design through launch and iteration.
Deep frontend expertise in React and TypeScript: component architecture, hooks, state management, data fetching (React Query, Apollo/GraphQL), and building accessible, performant data-heavy UIs.
Full-stack mindset — comfortable working across the stack: consuming and shaping API contracts, debugging data discrepancies with backend/analytics services.
Experience with analytics or BI products — dashboards, reporting, metrics exploration, financial/operational reporting, or similar; bonus if you've built charting, filtering, or self-serve analytics experiences.
Product sensibility — you care about restaurateur-facing UX, building trust through data, and collaborating with product and UX design on customer experiences.
Collaboration and communication — you work well with PM/Design/Data partners, give clear technical feedback, and thrive in a fast-moving, onsite, cross-functional environment.
Nice to have: experience with visualization libraries (e.g. Visx, D3, Recharts), Cypress E2E testing, internationalization (Rosetta), Mixpanel/product analytics, or data platforms (Cube, Pinot, warehouse-style analytics).
