Implement the client-side UI, local state, and URL handling for filter and search controls.
Maintain the viewer components for patent technical drawings (rotation, zoom, pagination) and document rendering.

Requirements

What you’ll need

3–5+ years of professional experience building production web applications with React and Next.js (or a comparable modern JavaScript framework).
Proven track record integrating front-end applications with REST APIs and handling asynchronous data, authentication tokens, and error states.
Experience writing end-to-end tests with Cypress or a similar tool (Playwright, TestCafe), and familiarity with unit/integration testing in general.
Demonstrated ability to own non-trivial frontend features end-to-end in an established codebase with minimal supervision, since this position operates as the single frontend owner of the web application.
Demonstrable frontend experience — a portfolio, public repositories, prior production work, or other concrete evidence of real project work.
English C1.
Desirable: Experience with data-heavy or analytics-focused applications and complex client-side state.
Familiarity with charting libraries (Chart.js, Highcharts, D3, Recharts, or similar).
Exposure to both modern (hooks-based) and legacy (class components, older Redux patterns, js) React code — the codebase is mid-migration, so working across both styles is part of the job.
Experience handling secured assets on the front end (pre-signed S3 URLs, token-based access).
Bachelor's degree in Computer Science, Software Engineering, Web Development, or a related field.
