Job Description
About Kernel
Kernel is crazy fast, open source browser infrastructure for AI agents. We handle autoscaling, observability, and the messy details of web interaction, so developers can focus on what their agents do instead of how they do it.
Teams at Cash App, Rye, and 3000+ others use Kernel for deep research, QA automation, and real-time web analysis. We've raised $22M from Accel, YC, and Vercel.
If you're interested in building critical infrastructure for agents on the web, we'd love to chat.
About the role
Product Engineers at Kernel are full-stack engineers who think about the product as much as the code. You know how to translate your strong product instincts into code, from pixel-level UI decisions to backend API design. You don't wait for a spec, you help write it.
You'll work closely with our co-founders to set product direction, ship full-stack features end-to-end, and make Kernel feel as polished as it is powerful.
What you’ll do
Own the full-stack implementation of user-facing product surfaces: dashboard, onboarding, website, and core product
Shape the product roadmap by synthesizing customer feedback, usage patterns, and your own instincts about what developers need
Drive DX improvements across our SDK, docs, CLI, and API. The kind of details that make developers say "this just works"
Ship fast and iterate, from prototype to production with minimal hand-holding
Help define what it means to build a great developer product at Kernel
What we're looking for
You ship end-to-end: you're comfortable owning a feature from frontend to backend and getting it across the finish line
You have product taste: you've thought hard about what makes developer tools feel magical vs. frustrating, and that thinking shows up in your work
Startup experience: you've built fast, worn multiple hats, and figured things out without a playbook
You build for developers deploying agents into the real world
You have strong opinions about devEx and API design, and you know how to back them up with shipped work
What you can expect as a Kernel
Industry-competitive salary
Above market equity
Premium medical + dental coverage + dependent coverage
Small, trusting team of senior + staff engineers
Default async with minimal bureaucracy, only two meetings a week
$1k / mo budget for LLM usage fees #vibecheck
Daily lunches on us
Unlimited PTO
401k + company match
Relocation assistance
Hiring process
We have a simple process focused on real world collaboration and jointly getting to know each other:
30-minute intro call with one of Kernel’s co-founders
45-minute technical interview (virtual)
Half-day on-site (virtual or in-person) working with our team on relevant challenges.
