Requirements
Requirements
  • Have 5+ years of product design experience, with the seniority to own complex work from discovery through shipped product
  • Start with the problem, not the screen, and have shipped work where discovery shaped the outcome
  • Have designed complex digital products end to end, with work you can walk through and explain
  • Have a portfolio that shows clear thinking, polished UI, and real outcomes rather than well-composed screens
  • Move fluidly between early discovery, rough prototypes, high-fidelity execution, and hands-on iteration with engineers
  • Treat prototyping as a way to think, test, and align, not just a deliverable to produce
  • Already work AI-native, with real opinions about where Claude Code or similar tools help and where they get in the way
  • Are a designer who builds, not one who hands off
  • Are solid across UX, interaction, IA, and visual design, with the technical curiosity to understand how the product behaves, not only how it looks
  • Bring high ownership and low ego, and can drive your own work forward while the team and product are still forming
Job Responsibility

  • Run discovery for your product area: talk to customers, dig into the problem, map workflows, and decide what's worth building before committing to a build
  • Become a domain expert for your part of the product, with a strong understanding of users, workflows, constraints, and business goals
  • Choose the right tool for each question: proper research when it warrants it, session data or support insights when that's enough, and a fast prototype when that answers it sooner
  • Own user flows, interactions, and interfaces from first discovery through to shipped product
  • Design for expert users doing complex work, making powerful workflows feel clear, fast, and simple enough to use every day
  • Talk to users directly through client calls, support tickets, and session data, and form product opinions from what you find
  • Work hands-on with engineers through the build, not just at handoff
  • Use AI tools, including Claude Code, to design, prototype, and iterate
