About the role

About KernelKernel 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.

  • Build OSS tools, libraries, and integrations that make Kernel's developer experience more powerful and easier to use

  • Engage with our community on GitHub/Slack/Discord/Twitter and in-person events, answering questions and amplifying cool projects

What We're Looking For:
  • You're a hands-on builder with LLMs and agents
  • 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

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
