Role Summary

Lead the delivery of high-impact product UI within Anaplan’s modern frontend platform. You will own complex features end-to-end—from technical design and implementation through testing, security remediation, observability, and production releases. You will mentor engineers, raise engineering standards, and influence patterns across React/TypeScript, monorepo architecture, design systems, and microfrontend boundaries.

What You’ll Do

• Architect and ship React + TypeScript features with strong component design, custom hooks, and performance tuning (render paths, memoization, code splitting, lazy loading).
• Drive design-system-first development using ADS and Material UI; extend shared components without fragmenting the UX.
• Own state and routing patterns: Redux at scale, pragmatic adoption of Zustand, and React Router v5 navigation and deep-linking concerns.
• Design and implement complex product UI: high-density grids, dashboards, widgets, drag-and-drop, and charts with resilient loading, error, and empty states.
• Define integration contracts for REST and GraphQL; partner on BFF (Backend-for-Frontend) design, pagination, caching, and client-side mapping layers.
• Advance monorepo practices (pnpm, Nx): shared libraries, versioning, build graph optimization, and cross-package API stability.
• Establish the testing strategy: Vitest + RTL (React Testing Library) for fast feedback; Cucumber + Playwright BDD E2E for critical journeys.
• Champion i18n (internationalization) and a11y (accessibility) using WCAG-oriented patterns, keyboard flows, screen reader behavior, and RTL/locale edge cases.
• Guide microfrontend and module federation boundaries (shared dependencies, runtime composition, isolation, and failure modes).
• Own Vite/Webpack build configuration tradeoffs, bundle analysis, and platform t
