HighLevel - Software Development Engineer II - Frontend
Requirements
• 2+ years building and operating production frontend applications • Deep Vue.js knowledge: the reactivity model, component composition, rendering • behaviour, and the runtime cost of each choice • A visible performance habit. You live in Lighthouse, Chrome DevTools and the performance profiler, and you can walk us through a regression you found, measured and fixed • Service workers and caching strategy: precaching, runtime caching, versioning, invalidation, and offline behaviour that stays correct • Client state management and local caching at scale (TanStack Query or • equivalent): cache keys, staleness, invalidation, optimistic updates • Accessibility as a build-time discipline: semantics, focus management, keyboard • paths, screen reader behaviour, WCAG 2.2 AA • Internationalisation and localisation: message extraction, plurals, locale-aware • currency and date formatting, RTL • Modern frontend tooling and module federation (Rspack, Vite), plus bundle analysis and code splitting • An eye for craft. You notice the four-pixel misalignment, the janky scroll, and the layout shift that only appears on a throttled connection, and you fix all three • Comfortable consuming typed backend contracts (ConnectRPC/protobuf) and reasoning about API contracts and error states • Excellent debugging and problem-solving skills • Frontend: Vue.js, Rspack, Module Federation, TanStack Query • Client platform: Service workers/PWA, OpenTelemetry, Vite, ESLint • Backend contracts: Go, ConnectRPC, Buf • Cloud: GCP (GKE), Pub/Sub • #LI-Remote #LI-SS1
Responsibilities
• Build and ship the commerce surfaces: storefronts, checkout, catalog, subscription management, invoices and documents • Embed our experiences inside other experiences — module federation, iframes and white-label hosts that stay isolated, load fast and degrade gracefully • Own performance budgets end to end: Core Web Vitals, bundle size, render cost, hydration, main-thread work. Measure them in CI and defend them • Build installable, offline-tolerant PWAs with service workers, considered caching strategies and background sync • Deliver WCAG 2.2 AA accessibility and full localisation across languages, currencies, tax and address formats, and RTL layouts • Instrument the client with real-user monitoring and OpenTelemetry so regressions surface before customers report them • Collaborate with PM/Design and mentor junior engineers
