About Kernel
Kernel provides enterprise RevOps teams with AI-powered company data for their CRMs. We raised $14M in Series A funding from top VCs and operators at Plaid, OpenAI, and Slack to build an AI-native alternative to Dun & Bradstreet's entity and hierarchy data.
RevOps teams at Navan, Gong, Mistral, and AlphaSense use Kernel to run their organizations.
At Kernel, we process 7B+ tokens a day and run 1.8M+ agents daily, all on an architecture that’s intentionally simple: one database, one queue. It’s minimalism built for massive scale (For reference, Wikipedia has 2.3B tokens in the English wikipedia). Our queue processes a daily volume on par with the entire Visa network’s transactions (~365M/day). All of which has been built by a small but mighty team of engineers.
The role
You’ll be Kernel’s first Product Designer - a foundational hire with end-to-end ownership of core product UX.
Your mission: simplify complexity. Make a powerful product feel effortless: clearer workflows, sharper mental models, fewer decisions, more confidence.
We’re not hiring for seniority. We’re hiring for impact.
What you’ll do
Own core UX end-to-end: flows, IA, interaction design, and visual craft.
Run ground-truth discovery: lead user interviews, synthesize fast, turn insight into shipped changes.
Prototype quickly: use whatever gets to a high-signal prototype (Figma, v0, Figma Make, etc.).
Ship with engineering + PM: tight loops, high quality in production, iterate fast.
Build the design foundation: principles, patterns, lightweight system - without slowing the team down.
5% “other stuff”: occasional help with decks/narrative when it moves the business.
What we’re looking for (impact > seniority)
You’ve shipped meaningful product work and can walk through decisions + outcomes.
You’re strong at simplifying complexity (not just polishing UI).
You can run discovery independently and get to the truth.
You move fast, communicate clearly, and collaborate tightly with engineers.
You have taste and execution: prototype → production details.
⚠️ This role may not be for you if you:
Need perfect clarity before starting.
Prefer long cycles and big “reveals.”
Want fully remote work (we move faster in-person).

We will do our best to offer you a ride of a lifetime. It will not be easy, but it will be thrilling.
