Senior Product Designer

fal is the generative media ecosystem powering the next generation of AI products. We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise. For developers and enterprises, fal is the foundation that makes generative media not just possible, but practical: a unified platform where high-performance inference, orchestration, and observability come together to unlock new categories of AI-native products. As generative media reshapes industries across a market projected to grow by hundreds of billions over the next decade, fal is becoming the ecosystem that ambitious teams build on. About this role: 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).
