Job summary

Kernel is hiring a Growth Marketer to own how engineers and technical decision-makers discover and start using Kernel. You will build a growth engine by instrumenting the funnel, running experiments, automating reporting, and feeding results into the next test to accelerate learning.

You will oversee SEO, docs, and AI-focused content, plus emerging channels that reach developers and AI assistants. Self-serve is core, so collaborate with Product, Engineering, Marketing and Sales to scale wins

Qualifications

• 4+ years in Growth at a developer-focused or deeply technical B2B product.
• You set your own roadmap and deliver on it, even when the brief is loose and priorities incomplete.
• You are data-driven. You understand incrementality, holdout and matched-market tests, and return on ad spend well enough to defend a budget.
• You've grown a self-serve funnel and can show the numbers: what you tested, what moved and why.
• You're deeply fluent in one or two channels and have working knowledge of the rest.

Responsibilities

• Measure and report the funnel from first visit through paid, including AI-referred traffic.
• Own SEO and discoverability across search and AI channels; optimize docs, llms.txt, structured data and cookbooks.
• Activate users from first visit to first successful session on Kernel.
• Run a structured testing program with a single log of hypotheses and results to inform next tests.
• Own a monthly paid acquisition budget and build alerts for scale decisions.

Job description

About KERNEL

KERNEL is infrastructure for AI agents to use the internet. Agents buy things, run back-office operations and test apps on KERNEL's browser infrastructure designed for performance, reliability and scale, with identity, observability and payments built in. KERNEL works with any agent harness or model and is trusted by Town, Middesk, Framer, Vercel and more than 20,000 teams. Founded in 2025, we are backed by $22M+ from top investors including Accel and Y Combinator.

Our vision is to be the internet runtime for agents. Agent traffic on the web is growing faster than human traffic, and the web needs new rails for access, identity and trust. We're building them.

About the role

We are hiring a Growth Marketer to own how engineers and technical decision-makers discover and start using KERNEL. You'll build a growth engine: instrument the funnel, run experiments, automate the reporting, and make every result feed the next test.

Developers find tools differently now. You'll cover traditional channels like social, search, and docs/content as well as AEO/GEO and new channels that reach AI assistants and coding agents that builders increasingly rely on. Our users are engineers, so technical credibility is critical.

Self-serve is core to how KERNEL grows, so you'll work just as closely with Product and Engineering as you do with Marketing and Sales.

You will own:

1. Measurement and reporting. Instrument the funnel from first visit through paid, including AI-referred traffic. Send weekly reporting against quarterly targets, set alerts for shifts in conversion or acquisition cost, and forecast monthly by working back from goals.

2. Discoverability across search and AI. Own SEO, and make KERNEL the answer when developers ask AI assistants or coding agents to do work on the Internet. That covers docs, llms.txt, structured data, comparison and integration pages, and our cookbooks.

3. Activation. Get developers from their first visit to a first successful session on KERNEL. Find where they drop off, and set the hypotheses and partner with engineering to build against it.

4. Experimentation. Run a structured program with one shared log of hypotheses and results, so each test informs the next.

5. Paid acquisition. Own a monthly budget and build the testing and alerts that drive scale-or-stop decisions.

What we're looking for

• You have 4+ years in Growth at a developer-focused or deeply technical B2B product.

  • Early-stage and founder experience is a plus.

• You set your own roadmap and deliver on it, even when the brief is loose and priorities incomplete.

• You are data-driven. You understand incrementality, holdout and matched-market tests, and return on ad spend well enough to defend a budget.

• You've grown a self-serve funnel and can show the numbers: what you tested, what moved and why. You've owned a performance marketing budget and can tell us how big it was and what it drove.

• You're deeply fluent in one or two channels and have working knowledge of the rest.

• You focus on the few bets that matter most, and you build systems instead of one-off campaigns.

• You are creative about finding new channels and experiments. You come up with unconventional bets that reach developers and their agents where nobody's tested yet.

• You use AI in your daily work, and are skilled at steering AI to accelerate on the most high-value work.

• You are excited to work on the frontier of the Agentic Internet, where standards are still undefined.

What you can expect at 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

• Daily lunches on us

• Unlimited PTO

• 401k + company match

• Relocation assistance
