Senior Product Designer (Core Product)

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.

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.

• 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.

• 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.

• 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.
