  • Design Systems Lead / UX Engineering Manager
  • Platform / Developer Experience (DX) Lead

Core Responsibilities

Primary Functions

  • Lead the design and evolution of frontend architecture for single-page applications (SPAs) and server-rendered apps, making pragmatic choices about frameworks (React, Next.js), rendering strategies (SSR/SSG/CSR), and module boundaries to optimize developer velocity and runtime performance.
  • Architect and maintain a scalable, documented component library and design system (Storybook, Bit, Figma integration) that ensures visual consistency, accessibility (WCAG 2.1), and reusability across multiple products and teams.
  • Own the frontend codebase quality through rigorous code reviews, standardized linting and formatting rules, TypeScript type hygiene, and enforceable patterns that reduce bugs and technical debt.
  • Mentor and grow a team of frontend engineers, set clear career development plans, coach on architecture decisions, and run periodic technical training sessions to raise overall frontend competency.
  • Lead planning and execution of large feature initiatives; break down complex features into scoped tasks, estimate effort, align dependencies with backend and design, and ensure on-time delivery.
  • Drive performance optimization initiatives — implement performance budgets, diagnose and fix bottlenecks using Lighthouse/Web Vitals, tree-shaking, code-splitting, lazy loading, and image optimization strategies.
  • Establish and run frontend CI/CD pipelines (GitHub Actions, CircleCI, Jenkins), automate release processes, and manage production rollouts with feature flags, canary releases, and observability hooks.
  • Design and enforce frontend security best practices: CSP, secure headers, XSS/CSRF mitigation, dependency vulnerability scanning, and secure session/token handling.
  • Own cross-browser and cross-device compatibility strategies; define polyfill, transpilation, and responsive design approaches for consistent UX across desktop, tablet, and mobile web.
  • Collaborate closely with Product and Design to translate user research and prototypes into engineered solutions, balancing product requirements with technical constraints and long-term maintainability.
  • Implement robust testing strategies for frontend code: unit (Jest), component (React Testing Library), visual regression testing (Chromatic), and end-to-end testing (Cypress, Playwright) to ensure high confidence shipping.
  • Lead the adoption and governance of state management solutions (Redux, Zustand, Recoil) and architectural patterns that scale for complex applications.
  • Drive API contracts and integration patterns with backend teams — optimize GraphQL or REST usage, client-side caching, offline support, and error handling strategies.
  • Implement internationalization (i18n) and localization strategies for multi-region products, including date/time/number formatting, RTL support, and locale-aware UI/UX.
  • Define and measure frontend KPIs (page load, Time to Interactive, CLS, error rates) and create dashboards (Datadog, Sentry, Google Analytics) to monitor health and iterate on reliability.
  • Manage monorepo architecture (Nx, Lerna, Turborepo) and package publishing processes for internal libraries, ensuring versioning, changelogs, and backwards compatibility.
  • Lead cross-team technical reviews and architectural decisions, write RFCs, and communicate tradeoffs and risks to engineering leadership and product stakeholders.
  • Participate in hiring: write job descriptions, screen resumes, conduct technical interviews, and help make hiring decisions that build a diverse, talented frontend team.
  • Create and maintain comprehensive frontend documentation: onboarding guides, architecture diagrams, coding standards, runbooks, and developer experience docs for new engineers.
  • Respond to and drive resolution of high-severity production incidents involving the frontend stack, perform root cause analysis, and coordinate post-incident fixes and preventative measures.
  • Research and introduce modern frontend tooling and frameworks (Vite, ESBuild, Webpack 5, React Server Components) where they provide measurable business or developer productivity benefits.
  • Own cross-cutting initiatives such as A/B testing infrastructure, analytics instrumentation, consent management for privacy/GDPR, and client-side experimentation platforms.
  • Balance hands-on coding with strategic leadership: contribute to critical code paths when needed but primarily enable the team to deliver high-quality frontend experiences consistently.

Secondary Functions

  • Support rapid prototyping and exploratory UX investigations to validate product hypotheses and accelerate time-to-market.
  • Contribute to the organization's frontend roadmap and technical strategy, advocating for investments in performance, accessibility, and DX.
  • Collaborate with business units and product managers to translate user needs into robust frontend requirements and acceptance criteria.
  • Participate in sprint planning, backlog grooming, and agile ceremonies to ensure clarity and alignment across multi-disciplinary squads.
  • Provide ad-hoc analytics and instrumentation recommendations for frontend experiments and feature launches.
  • Assist with vendor evaluation and management for frontend-related services (CDNs, image optimization, A/B testing providers).
  • Maintain a high-quality onboarding experience for new frontend hires, including curated learning paths and mentorship pairings.
  • Facilitate cross-team workshops and brown-bags on frontend best practices, accessibility audits, and architecture improvements.
  • Support continuous improvement of developer experience: faster local dev environments, better error messages, and streamlined PR processes.
  • Advocate for inclusive design and accessibility across product features, driving audits and remediation plans.
