Senior Front End Developer

This is a new role. The team has doubled in size over the past year. Part of this job is rebuilding an older AngularJS front end in React. Some of that work is unglamorous migration, and we won't pretend otherwise. Our team is spread across 17 countries. Headquarters is in Hillsboro. We hire in Nepal through an employer of record, so this is a regular full-time job with local payroll and statutory benefits. You will need at least 3 hours of overlap with US Pacific time. Equipment is provided, including a laptop.

Key responsibilities:

• Build UI features in React and TypeScript from Figma designs.
• Write unit tests with Jest and React Testing Library, and end-to-end tests with Playwright or Cypress.
• Track down cross-browser bugs in Safari, Chrome, Firefox and mobile browsers.
• Set up and tune build tooling (Vite, webpack, ESLint, Prettier)
• Profile and reduce bundle size, Core Web Vitals and time to interactive.
• Integrate with REST and GraphQL APIs and handle loading, error and empty states properly.
• Pair with backend engineers on API contracts before work starts.
• Maintain and extend the shared component library in Storybook.

Requirements:

• 5+ years building production web applications.
• Deep working knowledge of React (hooks, context, rendering behaviour)
• Strong JavaScript and TypeScript, including async code and the DOM.
• Comfortable using browser dev tools to debug network, layout and performance issues.

Benefits:

Rate: NPR 210,000 - NPR 250,000 per month

• 24 days paid time off.
• Annual learning budget.
• Co-working space stipend.
