Responsibilities

  • Own the architecture and technical direction of HighLevel’s platform frontend across multiple teams.
  • Design failure isolation, fallbacks, timeouts, and observability for federated application remotes.
  • Own independent deployment and versioning strategies, including contract testing, staged rollouts, and single-remote rollback.
  • Improve bundle size, dependency graphs, code splitting, shared chunks, preloading, prefetching, and caching/CDN performance.
  • Diagnose runtime performance issues including long tasks, re-render cost, list virtualization, memory leaks, and render thrash.
  • Define and instrument frontend performance metrics such as Core Web Vitals, INP, and route transition time.
  • Enforce accessibility, internationalization, and cross-browser support through automated quality checks.
  • Lead the frontend target architecture, application shell, module federation topology, shared component library, and design system implementation.
  • Write technical proposals, build consensus, review high-impact designs and code, mentor engineers, and drive change across teams without direct management.

Requirements

  • 9+ years of front-end development experience.
  • Expert-level JavaScript, TypeScript, HTML, and CSS skills with deep understanding of browser rendering, layout, the event loop, networking, caching, and memory.
  • Deep production experience with a modern component framework; Vue 3 and the Composition API are the primary technologies, with React, Angular, or Svelte experience accepted.
  • Demonstrated architectural ownership and experience migrating real codebases without freezing feature delivery.
  • Hands-on production experience with micro-frontends or module federation, or equivalent experience decomposing a large monolith.
  • Proven experience optimizing large-scale, complex web applications with measurable results.
  • Experience with build tooling at scale such as Vite, Webpack, Rspack, Turborepo, or Nx.
  • Working knowledge of accessibility engineering, including semantics, focus and keyboard behavior, ARIA, and screen reader testing.
  • Strong written communication for design documents, RFCs, and pull request descriptions in a remote-first asynchronous environment.
  • Experience mentoring engineers and driving change across teams without direct management.
  • Preferred qualifications include familiarity with Node.js, server-side rendering, and open-source contributions.

Benefits

  • Remote-first work environment with team members across 10+ countries.
  • Opportunity to remain hands-on while setting technical direction across multiple teams and leading multi-quarter migrations.
  • Work on a platform supporting more than 1 million businesses and large-scale distributed traffic.
