Founding Product Designer

Product & Design · Full-time · San Francisco / Remote

Apply ↓

Define the product experience for the data marketplace that helps creators, data owners, and AI teams transact with clarity and trust.

Sphere is creating new product primitives for data ownership, licensing, discovery, and purchase. You will shape the interfaces that make those workflows feel simple, credible, and fast.

This is a hands-on design role for someone who can move from product strategy to high-fidelity UI to implementation-ready details without needing a large design org around them.

What you'll do

  • Design polished product flows across onboarding, data upload, marketplace discovery, checkout, admin review, and buyer workspaces.
  • Turn ambiguous founder and customer feedback into clear wireframes, prototypes, interaction models, and visual systems.
  • Partner closely with engineering to ship production UI and keep product quality high across rapid releases.
  • Build reusable design patterns that help Sphere scale from founder-led product decisions to a durable product organization.

You may be a fit if

  • You have experience designing production SaaS, marketplace, developer tool, fintech, or data infrastructure products.
  • You have excellent product judgment and can explain why an interface should work a certain way.
  • You are comfortable working in Figma, prototyping quickly, and collaborating directly with engineers.
  • You care about dense, trustworthy, high-clarity product surfaces rather than decorative design for its own sake.
