Solutions Engineer
Kernel · San Francisco
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 5000+ 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
You'll carry a technical sales motion end-to-end: running discovery, architecting solutions, and seeing customers through to production. That means you're as comfortable in a sales conversation as you are in a terminal. You'll work closely with our founders on strategic deals, help developers understand what's possible with Kernel, and design the systems that make our customers successful.
This role sits at the intersection of sales, engineering, and product. You'll influence Kernel's roadmap through direct customer feedback, serve as the primary technical point of contact for strategic accounts, and make sure customers go from demo to production without getting stuck.
What you'll do
Own the technical sales motion alongside our founders: discovery, demos, solution design, and closing
Architect customers' production systems: CUA agents, browser automations, web agents, and everything in between—helping them think through system design, concurrency, observability, and failure modes
Debug integration issues across our SDK, MCP server, browser automation edge cases, and customer code
Champion customer requirements internally and collaborate with engineering to close gaps between current functionality and what customers need next
Contribute to technical content like integration guides
What we're looking for
5+ years in a technical customer-facing role: solutions engineer, sales engineer, solutions architect, or similar
Strong engineering foundation—you can read and write code, dig into SDK internals, and hold your own in a technical conversation with a senior engineer
Track record of owning a technical sales motion
Comfortable translating between technical and non-technical audiences without losing precision in either direction
Love creating demos that help developers understand what’s possible with Kernel
Experience driving complex, cross-functional deals and projects from first call to go-live
High tolerance for ambiguity—many of our customers are building things that don't have a playbook yet
Experience building with AI agents, MCP servers, or LLM-integrated workflows
Even better:
Familiarity with browser automation or agent infrastructure (Playwright, CDP, headless browsers)
Prior experience at a developer infrastructure or API-first company
Experience working on deals with enterprise customers
You've shipped something public: OSS, a demo, a tool—anything that shows you build, not just advise
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
$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 onsite interview (in-person preferred) working with our team on relevant challenges.
