About this role

Browserbase

Browserbase is the complete platform to build and deploy agents that browse and interact with the web like humans. We provide one API key for agents to search and fetch information, fill out forms, and replicate user actions.

We are a Series B startup that grew our revenue 5x in 2025 and are continuing to grow, fast. Backed by Kleiner Perkins, CRV, and Notable Capital, our team is building on our CEO's founding vision to power the world's best AI tools and help everyone automate the web.

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.
Document as you go and share your knowledge with the team.

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.

You're a good fit if you:

Have high agency: you can set direction, make judgment calls, and drive projects forward without waiting for perfect clarity.
Have a strong sense of ownership and bias toward action.
Can drive projects independently, with high accountability without much outside input.
Communicate clearly in writing and in person, and choose the right medium for the message.
Are adaptable and able to dive into unfamiliar systems, learn quickly, and make sound technical decisions.
Enjoy collaborating with a small, ambitious team in a fast-paced environment.
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.
Collaborate with a small, high-bar team of engineers who care deeply about quality.
Join an ambitious startup where your impact will be felt immediately.
