About the Role:

You'll build and maintain the customer-facing dashboard that powers Webshare's proxy infrastructure. Our Next.js application serves many active users managing billions of proxy requests daily. You'll work on a modern React 19 + TypeScript stack with a highly autonomous team, balancing new features, experiments, and technical improvements.

Build and maintain performant frontend applications using Next.js 15, React 19, and TypeScript that power Webshare's proxy management dashboard.

Own the design and delivery of UI features covering subscriptions, proxy configuration, analytics, user management, and payments (Stripe integration).

Collaborate in a highly autonomous team to scope, plan, and execute work with minimal meetings.

Investigate and resolve production issues using Sentry error monitoring and DataDog browser RUM.

Balance time equally between features, experiments, tech debt, and bug fixes.

Write comprehensive tests using Jest, Testing Library, and Playwright for E2E coverage.

Develop and maintain component library with Storybook and Material UI (MUI 7).

Continuously improve performance, accessibility, and user experience.

Strong experience with TypeScript and modern React (hooks, context, concurrent features).

Proven experience with Next.js (App Router, SSR/SSG, API routes).

Familiarity with Material UI or similar component libraries.

Experience with data fetching patterns (SWR, React Query, or similar).

Comfortable writing tests (unit, integration, E2E).

Understanding of web performance optimization techniques.

English fluency to thrive in a remote team.

Fluency with AI-assisted development tools (Copilot, Cursor, Claude Code) and the judgment to know when they accelerate your work versus when they get in the way.

Nice to have:

Experience with Storybook for component development.

Familiarity with payment integrations (Stripe).

Experience with observability tools (Sentry, DataDog, PostHog).

Knowledge of charting libraries (Recharts, D3).

Understanding of proxy/networking concepts.
