Fal

Senior Product Designer

San Francisco , United States

AI overview

Own end-to-end product design for web and mobile experiences, leveraging AI tools to prototype and validating designs through user research in a fast-paced startup environment.

You are a versatile designer who thrives with ambiguity, who can move at fal speed while keeping the UI fast + consistent.

Must Have

  • Strong product UI/visual craft + portfolio of shipped work.
  • Experience designing web AND mobile product experiences: can create dedicated mobile screens (not just “responsive web”) and understands mobile UI patterns, navigation paradigms, constraints, and edge cases.
  • Solid design systems experience (components/tokens/variants/docs + working with engineering for adoption).
  • Comfortable owning features end-to-end (flows → UI → handoff → QA) in a high-velocity startup.
  • AI-assisted / “vibe coding” prototyping mindset (uses modern tools to prototype quickly; production code not required, but code-based prototyping is a plus).
  • Can run scrappy user research/testing and iterate based on customer feedback.
  • Accessibility + responsive fundamentals (but again: must also design true mobile experiences).
  • Strong cross-functional communication; can define success metrics with PM/Eng and iterate post-launch.

Key responsibilities

  • Own end-to-end product design for features (problem framing → flows → UI → states/edge cases → handoff → QA → iterate).
  • Design across web + true mobile experiences (dedicated mobile screens + mobile patterns; not just responsive web).
  • Help build/maintain the design system (components/tokens/patterns/docs) and drive adoption with engineering.
  • Prototype fast (Figma + AI/vibe-coding tools when useful) to validate direction.
  • Partner tightly with Eng/PM to ship quickly, keep quality high, and improve post-launch with feedback.
  • Do lightweight user research/testing (scrappy usability checks, customer calls, quick validation).
  • Nice-to-have “extra output” when needed: Google Slides decks + light graphic/brand assets.

Nice to have

  • Familiarity with generative media / LLMs / image (or video) models and the UX patterns around prompts, parameters, evaluation, latency/quality tradeoffs.
  • Front-end literacy (React/TypeScript/CSS) and/or Storybook-style component workflows.
  • Willing to support lightweight GTM/design needs sometimes: pitch decks (Google Slides) and basic graphic design (simple visuals, social cards, light marketing assets).
  • Any experience (or interest) in graphic design / brand design (doesn’t need to be a brand lead—just enough taste/skill to help when needed).
