Kernel is a developer platform that provides Crazy Fast Browsers-as-a-Service for browser automations and web agents. Our API and MCP server allow developers to instantly launch browsers in the cloud without managing infrastructure.
Our serverless browser platform handles the hard stuff: autoscaling reliable browser infrastructure, observability, and the messy details of web interaction so developers can focus on what their agents do, not how they do it. Kernel makes AI tangible, practical, and powerful, allowing developers to deploy agents that can truly interact with the digital world.
We’re used by teams at Cash App, Rye, and countless others for tasks like deep research, QA automation, and real-time web analysis. We've raised $22M from Accel, YCombinator, Vercel, Paul Graham, Solomon Hykes (Docker), David Cramer (Sentry), Charlie Marsh (Astral), and more.
One line of code deploys any web agent to our cloud. The rest is up to you. If you're interested in building critical infrastructure for the next generation of AI applications, we'd love to chat.
About the role
As an Infrastructure Engineer at Kernel, you’ll architect and build the core systems that power our AI agent platform end-to-end.
