About the role

• Senior Product Engineer developing cutting-edge web data scraping solutions for clients including Fortune 500 companies. Building applications using modern frameworks like Next.js and React.

Responsibilities

• Own features from problem discovery through delivery and iteration, including subscriptions, proxy configuration, analytics, payments, and more.
• Shape the product roadmap alongside engineering and product leadership, using data, user feedback, and your own judgment.
• Build and maintain performant applications in Next.js 15, React 19, and TypeScript. Our frontend is your primary surface area, but you'll cross into APIs and backend services when the problem demands it.
• Design and run experiments to validate ideas before investing in full builds.
• Investigate production issues using Sentry, DataDog, and PostHog, closing the loop between what we ship and what users actually experience.
• Write tests (Jest, Testing Library, Playwright) proportional to risk, not ceremony.
• Improve the developer experience: component library, tooling, CI pipeline, and patterns that help the team move faster.
• Balance your time across new features, experiments, tech debt, and bug fixes. You'll have the autonomy to make that call.

Requirements

• Strong TypeScript and modern React experience (hooks, context, concurrent features).
• Experience with Next.js or similar SSR frameworks.
• Product instinct. You think about who uses what you build and whether it's working, not just whether it compiles.
• Comfort with ambiguity: you can take a vague user problem and turn it into a concrete plan.
• Familiarity with analytics and experimentation (PostHog, Amplitude, LaunchDarkly, or similar).
• Solid testing habits across unit, integration, and E2E.
• English fluency for a distributed, async-heavy team.
• Nice to have: Experience with Material UI or similar component systems.
• Familiarity with payment integrations (Stripe).
• Exposure to backend work: Python/Django, REST APIs, or similar.
• Knowledge of web performance optimization (Core Web Vitals, bundle analysis).
• Understanding of proxy/networking concepts.
• Experience with Storybook, charting libraries (Recharts, D3), or observability tooling.

Benefits

• expansive benefit package covering learning, well-being, celebration, and more
