Integrate with internal and third‑party APIs; deliver fast, resilient flows with optimistic updates. Help evolve our design system and shared component libraries with Storybook. Improve performance and reliability through smart architecture, testing, and monitoring. Contribute to a strong engineering culture via reviews, mentoring, and documentation. Projects you might work on Applicant Tracking System (ATS) – Build core hiring pipelines, candidate profiles with activity timelines, evaluations, mentions, and role‑based permissions. Integrate email/SMS, calendars, and job boards; add resume parsing, search, rules/automation, event‑driven updates, and compliance (audit logs, GDPR). Design System & Component Library – Tokens, theming, accessible primitives (WCAG 2.1 AA), and Storybook docs with visual regression tests for cross‑app reuse. Microfrontends Platform – Build a Module Federation strategy (shared components, utilities, and routing contracts) with independent deploys and semantic versioning. Scheduling Platform – Calendar integrations, timezone handling, availability UI, and live status changes tied to an event‑driven backend. Notifications / In‑App Messaging – EDA‑powered toasts, inbox, and subscription UIs with background sync and conflict resolution for async tasks. Performance Optimizations – Code‑splitting, bundle analysis (Webpack/Vite), image optimization, and Next.js SSR/SSG tuning to hit CWV targets. Experimentation & Feature Flags – A/B tests, gradual rollouts, and telemetry loops to validate UX hypotheses from AI‑assisted prototypes. Developer Experience – CI/CD previews, component scaffolding, ESLint/Prettier standards, and auto‑generated docs to keep the front‑end flywheel smooth. Qualifications 5+ years building production React apps; expert in modern JavaScript and the browser. Strong proficiency integrating with REST/GraphQL APIs, including auth, error handling, and caching strategies. Solid experience with state management (Redux Toolkit, Zustand, React Query/TanStack Query). Experience with Webpack (or Vite), Git, testing (Jest, Playwright, Cypress), and accessibility. Comfortable collaborating in UI design & prototyping tools (e.g.: Figma, Sketch, Adobe XD) and with AI‑driven prototypes. Strong eye for detail and quality; experience working closely with designers. Autonomy and demonstrated ability to learn quickly. Ability to communicate fluently in English (C1). You live in Mexico with a current CURP. Preferred TypeScript in production (strict mode, generics, utility types). Microfrontends experience, ideally Module Federation with shared contracts, versioning, and independent deploys. Event‑driven/real‑time UIs (WebSockets/SSE). Design systems at scale (design tokens, theming) and Storybook with visual regression (Chromatic/Playwright). Deep performance experience (Lighthouse/Core Web Vitals, code‑splitting, bundle analysis with Webpack/Vite, caching/CDN). Testing culture: Jest, React Testing Library, Cypress/Playwright. Solid API know‑how (REST/GraphQL, pagination, retries/backoff, ETags) plus auth flows (OAuth2/OIDC/SAML) and security basics (OWASP). Observability for frontend (Sentry, OpenTelemetry traces), analytics (Google Analytics, Mixpanel) and experiment platforms (feature flags/A/B). PWA skills (service workers, offline strategies, background sync). Domain context in ATS/HR workflows (pipelines, scorecards, compliance like GDPR/EEOC) is a plus.
