About the role

Browser Use is six people at an eight-figure annualized run rate. Our open-source project has 110K+ GitHub stars. We are building the infrastructure that lets millions of agents use the web.

Running one browser is easy. Running millions of isolated browsers for agents without everything becoming slow, unreliable, insecure, or insanely expensive is not.

I need someone to own that problem completely.

What you will own

- Build the infrastructure between agents and browsers.

- Scale ephemeral workloads across AWS without breaking as usage explodes.

- Own Kubernetes, Terraform, CI/CD, monitoring, and incident response.

- Push latency down, throughput up, and infrastructure cost down.

- Build security into the system from the beginning.

- Design our multi-cloud and on-prem infrastructure across AWS, Azure, and GCP.

- Make the architecture and vendor decisions we will still be living with years from now.

This is not a job where you inherit a mature system and keep it alive. You will decide what the foundation should be and build it while the company is growing underneath you.

The bar

You have scaled serious AI or ML infrastructure on AWS. You have supported at least 100K users in production and have deep experience with Kubernetes, Terraform, Python, GPU orchestration, and model serving.

Browser infrastructure experience is a huge advantage. You understand how browsers behave at scale and have worked with Playwright, Puppeteer, or CDP. Experience with ephemeral workloads, infrastructure cost optimization, AI-native clouds, open source, or being an early infrastructure hire also helps.

More important than any keyword: when something breaks in a way nobody has seen before, you get excited and keep digging until you understand it.

How we work

We are not trying to build a nice little company. We want to build one of the biggest companies in the world.

We play to win. We move fast, keep things simple, and tell each other the truth. The company is a championship team, not a family. We care deeply about each other, hold extremely high standards, and put the mission first.

This is an extremely intense, in-person role. If you want remote work, predictable hours, or a comfortable pace, do not apply.

If you see 110K GitHub stars and immediately start thinking about what will break at 100x the scale, we should talk.

Apply

Send your GitHub and a short note about the gnarliest infrastructure problem you have solved.

We move fast.
