About Kernel
Kernel provides crazy fast, open source infrastructure for AI agents to use the internet. Our API allows developers to instantly spin up secure browsers and automate anything on the web. We handle all the hard problems of running browser-based agents in production: agents x user credentials, autoscaling, bot detection, and human-in-the-loop workflows.
We’re used by teams at Cash App, Vercel, Framer, Rye, and over 5000 developers for tasks like QA automation, RPA, virtual assistants, and CUA RL environments. We've raised $22M from Accel, YCombinator, Vercel, Paul Graham, Solomon Hykes (Docker), David Cramer (Sentry), Charlie Marsh (Astral), and more.
About the role
We are an infrastructure company and developers are our core users. As a Developer Advocate, you'll be the public voice of Kernel for developers: creating content, engaging with the community, and bringing insights back to our product and engineering teams. You'll help define how builders learn about browser infrastructure, adopt Kernel, and push the frontier of what AI agents can do on the live Web.
What you’ll do
Build OSS tools, libraries, and integrations that make Kernel’s developer experience more powerful and easier to use
Create high-quality tutorials, guides, and demos showcasing Kernel's core and emerging capabilities
Iterate on Kernel's developer documentation as a first-class product surface
Engage with our community on GitHub/Slack/Discord/Twitter and in-person events, answering questions and amplifying cool projects
Contribute to Kernel’s technical blog, developing content that educates, inspires, and grows developer adoption
What we’re looking for
Hands-on familiarity with generative AI, especially agents, MCP, and Kernel
Strong technical foundation in software engineering or applied AI. You're comfortable building code samples, demos, and lightweight apps
Developer empathy: you know what excites them, what annoys them, and how to speak their language (our inspirations: Modal, Supabase, PlanetScale)
Skilled communication abilities with a clear, engaging style across writing, video, and live presentations
Curiosity, high-agency, and a genuine passion to build something that delights software engineers
What you can expect as a Kernel
Industry-competitive salary and equity
Premium medical + dental coverage + dependent coverage
Small, high-trust team of senior + staff engineers
Default async with minimal bureaucracy
$1k / mo budget for LLM usage fees #vibecheck
