Everything that makes you unique is welcome; join us and let’s build what’s next - together! Role summary Lead delivery of high-impact product UI in 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 mentor engineers, raise engineering standards, and influence patterns across React/TypeScript, monorepo architecture, design systems, and microfrontend boundaries. What you’ll do • Architect and shipReact + TypeScriptfeatures with strongcomponent design,hooks, andperformancetuning (render paths, memoization, code splitting, lazy loading). • Drivedesign-system-firstdevelopment usingADSandMaterial UI; extend shared components without fragmenting UX. • Own state and routing patterns:Reduxat scale, pragmatic adoption ofZustand,React Router v5navigation and deep-linking concerns. • Design and implementcomplex product UI: high-densitygrids,dashboards,widgets,drag-and-drop, andchartswith resilient loading/error/empty states. • Define integration contracts forRESTandGraphQL; partner onBFFdesign, pagination, caching, and client-side mapping layers. • Advancemonorepopractices (pnpm,Nx): shared libraries, versioning, build graph optimization, and cross-package API stability. • Establish testing strategy:Vitest+RTLfor fast feedback;Cucumber+PlaywrightBDD E2E for critical journeys. • Championi18nanda11y(WCAG-oriented patterns, keyboard flows, screen reader behavior, RTL/locale edge cases). • Guidemicrofrontendandmodule federationboundaries (shared deps, runtime composition, isolation, failure modes). • OwnVite/Webpackbuild configuration tradeoffs, bundle analysis, and platform tooling (Docker/Tilt, feature flags, internal API clients). • Leadproduction support: debug withGrafana,Splunk, distributed traces/logs; write actionable incident notes and preventative fixes. • Ownrelease to production: release trains, rollback judgment, coordination with SRE/platform,Harness/Argo CDpipelines. • ResolveSnyk,SAST, and dependency vulnerabilities; embed secure SDLC practices in team workflows. • Mentor junior/mid engineers via reviews, pairing, and technical RFCs; represent frontend in cross-team design reviews. • Optionally lead or spikeReact Nativeinitiatives (native tooling, debugging, shared logic extraction). Required qualifications Core web (expert-level application) • DeepHTML/CSSskills applied through design systems, not ad-hoc styling. • AdvancedTypeScript(generics, discriminated unions, utility types, strict typing for API models). • Web Componentsliteracy (custom elements, shadow DOM, interoperability with React hosts where applicable). React platform leadership • 5+ years building large, long-lived frontend products; 3+ years leading features inReact. • Provenperformanceoptimization in data-heavy UIs (virtualization, debouncing, selector patterns, profiling). • Strongcomponent API design: composability, accessibility props, testability, and extension points. Architecture & tooling • Production experience withmonorepos(pnpm,Nx), shared packages, and internal design libraries. • Viteand/orWebpackexpertise; familiarity withmodule federationandmicrofrontendoperational concerns. • GraphQLclient patterns (caching, error policies, colocated queries) plus robustRESTclient abstractions. • BFFcollaboration: shaping payloads for UI needs, auth/session handling at the edge of frontend concerns. Quality, security & operations • Testing leadership:RTL+Vitest, meaningful coverage of behavior (not implementation detail); E2E strategy withPlaywright/Cucumber. • Hands-onvulnerability remediation(Snyk, npm audits,SASTtriage) and secure dependency management. • Production debugging andobservability(Grafana,Splunk); SLO-aware mindset for customer-impacting defects. • CI/CD and release ownership (GitHub Actionsor equivalent,Harness,Argo CD). Leadership & delivery • Track record mentoring engineers and raising code quality through reviews and standards. • Strong stakeholder communication (Jira, RFCs, estimations, risk callouts). • Experience taking features through full lifecycle including production rollout and post-release monitoring. Nice to have • React Native+ native build/debug (Xcode/Android tooling) for shared mobile roadmap/ Next js •
