Kernel are hiring a

Senior Product Designer (Core Product)

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 & Bradstreets 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 thats intentionally simple: one database, one queue. Its 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 networks transactions (~365M/day). All of which has been built by a small but mighty team of engineers.

The Role

Youll be Kernels 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.
Were not hiring for seniority. Were hiring for impact.

What Youll 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 Were Looking For (Impact > Seniority)

  • Youve shipped meaningful product work and can walk through decisions + outcomes.
  • Youre 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).
