About the Role

Agent Platform is Browserbase’s framework for automating browsers with code. The Agent Platform team creates developer tools at the intersection of AI and open source, making browser automation smarter, simpler, and more powerful.

What you'll do

• Build, operate, and grow the Agent Platform framework — developer-first APIs with ~2M monthly downloads and ~17k stars. Design and implement tools that make automating the web simple and powerful.
• Work with frontier AI labs (OpenAI, Google, and others) to improve models, benchmark capabilities, and make them more accessible to developers.
• Deploy production-ready AI solutions that impact millions of customers, shaping the future of the web.
• Help define, scope, and prioritize projects that shape the future of developer tooling.

Technical skills

• Strong coding skills: preferably TypeScript; also valuable: Python/Go.
• Experience building developer tools, frameworks, or libraries that others depend on.
• Experience building AI agents/LLMs, distributed systems, or applying reinforcement learning.
• Familiarity with web automation frameworks (Puppeteer, Playwright, Selenium) or web scraping; huge bonus: Chrome DevTools Protocol (CDP) experience.
• Track record of open source contributions or public developer projects.
• Have a strong sense of ownership and bias toward action.
• Are excited to work 4 days a week (WFH Wednesday) in our San Francisco HQ (or open to relocating here).

Why join us

• Shape the future of browser automation with AI-driven developer tools.
• Work in the open: collaborate with and contribute to the broader open source community.
