Frontend Architect

Job Description



What will I be doing?
  • Define and steward the frontend architecture (frameworks, component patterns, state management, routing, SSR/SSG/ISR) across teams.
  • Establish and evolve an organization-wide frontend baseline (Node LTS policy, package manager posture, canonical scripts, lint/format, TypeScript strictness, testing posture, CI templates) with clear adoption guides.
  • Design frontend–backend integration (API contracts, versioning, error handling, caching, BFF when appropriate) to ensure reliable and observable interfaces.
  • Lead web performance strategy (code splitting, asset budgets, image/fonts strategy, hydration, caching/CDN), setting targets and enabling measurement.
  • Ensure accessibility (WCAG), i18n/l10n, and client-side security (CSP, auth flows, token handling, XSS/CSRF mitigations) are built into the architecture.
  • Drive developer experience: tooling, monorepos and/or micro-frontends when justified, starter templates, documentation, and examples.
  • Mentor technical leads/referents, participate in technical reviews, and author ADRs/RFCs that align architecture with business goals.
  • Collaborate with UX, Product, and Backend to align technical decisions with user and business outcomes.

  • What skills do I need?
  • 8+ years of professional web development experience and 3+ years in technical leadership or frontend architecture roles.
  • Expert knowledge of React and TypeScript; hands-on experience with SSR frameworks (e.g., Next.js or similar).
  • Strong command of build/bundle tooling (e.g., Vite/Webpack), testing (Jest/Vitest, Testing Library, Playwright/Cypress), and quality gates (ESLint/Biome, Prettier).
  • Demonstrated web performance optimization and observability experience (Core Web Vitals, profiling, RUM).
  • Solid understanding of frontend security best practices and modern authentication/authorization patterns in web apps.
  • Experience integrating CI/CD for frontend projects and working with design systems/component libraries.
  • Excellent communication skills; ability to write clear technical documentation and guide cross-team alignment.
  • Node.js experience for BFF/SSR and familiarity with edge rendering/CDN strategies.
  • Experience with micro-frontends, large-scale design systems, and monorepo tooling (Nx/Turborepo).
  • Exposure to cloud platforms and delivery of frontend at scale (e.g., AWS/GCP, CloudFront/Fastly/Akamai).
  • Telemetry and monitoring for web applications (e.g., Datadog, Coralogix, Grafana/Prometheus).
  • English (intermediate to advanced) for documentation and cross-team collaboration.
