Job description

Browserbase powers web browsing capabilities for AI agents and applications. We manage headless browser infrastructure for automations that interact with websites, fill out forms, and replicate user actions.

We raised a $40M Series B last year and are continuing to grow, fast. Backed by Kleiner Perkins, CRV, and Notable Capital, our fast-moving team is building on our CEO's founding vision to power the world's best AI tools and help everyone automate the web.

Core (aka Browserbase Core Infrastructure) is the backbone of everything we do. This team keeps our browsers running at scale, solving massive distributed systems challenges and making sure our platform is fast, reliable, and scalable.

What you’ll do

• Build, operate, and grow the Browserbase Core platform — designing and developing robust, scalable distributed backends with developer-friendly APIs.

• Work closely with the rest of Engineering, gathering input and providing great support so every team can build on Core with confidence.

• Help define, scope, and review key projects; set priorities on the roadmap; and sequence deliverables that push the platform forward.

• Establish and reinforce best practices around development, operations, and reliability.

• Continuously enhance the platform to meet rapidly expanding customer adoption and demand.

• Investigate, troubleshoot, and resolve operational issues that arise in production.

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

Technical skills

• Deep experience building and scaling distributed systems, with scale on the order of hundreds or thousands of instances.

• Strong expertise coding in Go or Typescript; bonus if you’ve touched Firecracker or similar VMMs.

• Familiarity with CI/CD pipelines, Kubernetes and Docker, message queues, relational databases, automated testing, performance optimization, and zero-downtime multi-region deployments.

• A systems-thinking mindset you understand how infrastructure choices ripple all the way up to customer experience.

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 5 days a week in our San Francisco HQ (or open to relocating here).

Why join us

• Work on some of the hardest problems in modern infrastructure.

• Collaborate with a small, high-bar team of engineers who care deeply about quality.

• Build core technology that every Browserbase product depends on.

• Join an ambitious startup where your impact will be felt immediately.
