Senior Product Designer

Hi there! We are fal, and we are on a mission to build world’s first generative media platform for developers.

We built a serverless runtime for Python that is optimized to run large ML models on 1000s of GPUs efficiently. The applications built on our platform are currently serving millions of users around the world and our goal is to 1000x that over the next few years.

fal is an in-person company based in San Francisco. Today, we are 80 people strong, and we are looking for team members who share our excitement about the fast moving nature of AI and can independently build world‑class infrastructure.

Full time

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

• 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).
• 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 also design true mobile experiences).
• Strong cross‑functional communication; can define success metrics with PM/Eng and iterate post‑launch.

• 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.

• Familiarity with generative media / LLMs / image (or video) models and the UX patterns around prompts, parameters, evaluation, latency/quality tradeoffs.
• Front‑end literacy (React/Type Script/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).

• Interesting and challenging work
• Competitive salary and equity
• We are currently hiring in downtown San Francisco. We prefer to work in‑person but we also offer remote work opportunities for exceptional candidates.
• We offer visa sponsorship and will help you relocate to San Francisco.
• Health, dental, and vision insurance (US)
