Senior Frontend Engineer

Our team is growing and we are hiring a Senior Frontend Engineer. 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 9 countries. Headquarters is in New York City. This is a full-time remote role. We use an employer of record in Germany, so you get a proper employment contract, not a freelance agreement. Core hours are 9:00 AM to 1:00 PM US Eastern. We use Slack, Notion and Google Meet. Cameras on for team calls.

Your responsibilities

• Set up and tune build tooling (Vite, webpack, ESLint, Prettier)
• Profile and reduce bundle size, Core Web Vitals and time to interactive.
• Pair with backend engineers on API contracts before work starts.
• Fix accessibility issues and test with VoiceOver and NVDA against WCAG 2.1 AA.
• Write unit tests with Jest and React Testing Library, and end-to-end tests with Playwright or Cypress.
• Manage client state with Redux Toolkit, Zustand or TanStack Query.
• Track down cross-browser bugs in Safari, Chrome, Firefox and mobile browsers.
• Work with designers to adjust interactions when something doesn't hold up in the browser.

What you'll need

• 5+ years building production web applications.
• Comfortable using browser dev tools to debug network, layout and performance issues.
• Familiarity with accessibility standards and semantic markup.
• Experience with a styling approach such as Tailwind, CSS Modules or styled-components.

Nice to have

• Internationalization (i18n) and right-to-left layouts.
