Job Description

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.

Job Responsibility

  • 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

Requirements

  • 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

What we offer

  • Offers Equity
  • 24 days holiday per year + bank holidays
  • 2 weeks work-from-anywhere
  • Pension plan
  • Top-spec equipment and central London office
  • High-autonomy, high-trust environment with a small team shipping at pace
  • Free dinner at the office
  • Team events and dinners
  • Work directly with the founders to scale the systems that power enterprise AI
  • Visas & Relocation support
