About the role

Founding Product Designer shaping Kernel’s product experience, focusing on simplifying complexity and building a product people love to use.

Responsibilities

  • 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, code, 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.

Qualifications

  • Founding designer experience is a plus, but not a requirement - what matters most is that you have early-stage startup experience and can point to tangible examples of transforming a business through design.
  • 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.
