Frontend Engineer II — Vue, PWAs & Performance

HighLevel; United States; Remote; USD 120,000 - 160,000; Full time

Job summary

HighLevel is building a global, remote-first commerce platform. As an SDE II on the frontend, you’ll craft storefronts, checkout flows, catalogs and invoices that power $1T+ in annual transactions for millions of SMEs.

You’ll own performance budgets, optimize bundle sizes, and implement offline-capable PWAs with robust caching strategies, while ensuring WCAG 2.2 AA accessibility and full localisation. Join a fast-moving team driving craft and scale.

Qualifications

• 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.
• Service workers and caching strategy: precaching, runtime caching, versioning, invalidation, and offline behaviour that stays correct.
• Internationalisation and localisation: message extraction, plurals, locale-aware currency and date formatting, RTL
• Modern frontend tooling and module federation (Rspack, Vite), plus bundleanalysis 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

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
