Copperleaf Technologies is looking for a Principal Frontend Engineer to join a small, steady team. Part of this job is rebuilding an older AngularJS front end in React.

Reliable internet and a power backup are a must.

What you'll be doing:

Build UI features in React and TypeScript from Figma designs. Profile and reduce bundle size, Core Web Vitals and time to interactive. Manage client state with Redux Toolkit, Zustand or TanStack Query. Fix accessibility issues and test with VoiceOver and NVDA against WCAG 2.1 AA. Integrate with REST and GraphQL APIs and handle loading, error and empty states properly. Add analytics events and help product read the results. Work with designers to adjust interactions when something doesn't hold up in the browser.

Requirements:

7+ years building production web applications. A good eye for spacing, alignment and small visual details. Experience with a styling approach such as Tailwind, CSS Modules or styled-components.

Compensation and benefits:

Rate: $1,850 to $2,050/month

Company laptop. Annual rate review. Flexible hours.

If you are shortlisted, we will reach out to set up a first call.

Candidates must be eligible to work in Pakistan.

Duration: 12 months. Start: Within 30 days.
