Responsibilities: Build the product from the ground up — define its visual language, design principles, design system, and key UX flows. Design UX for an AI-powered product — including onboarding, first-generation experiences, long-running asynchronous processes, AI model selection, token-based economics, error states, and web-first checkout. Build a scalable design system for web and mobile, with shared logic, components, variables, themes, states, and responsive behavior. Design production-ready motion — micro-interactions, loading states, transitions, and animations that help users understand what is happening during AI generation. Create implementation-ready animations using Rive (preferred) or Lottie, and collaborate closely with engineers on their integration. Design for real traffic from day one — the MVP will reach live users shortly after launch, so you’ll continuously validate and improve your work based on user behavior and product data. Work closely with engineers to balance UX quality, visual polish, and implementation complexity. Contribute to product growth by designing experiences that improve activation, conversion, monetization, and retention. Contribute to the product’s visual identity through typography, color systems, logo direction, and other foundational brand elements. Collaborate closely with the CEO, product, and engineering teams to turn ambiguous problems into clear, scalable product experiences. Requirements: 4+ years of experience in product design, ideally in B2C products with paid traffic or performance marketing. Strong experience designing both web and mobile products, ideally with a unified design system across platforms. Experience with production-ready motion design, with Rive preferred or Lottie as an alternative. Proven experience building design systems with reusable components, states, variables, themes, and responsive scenarios. Strong product thinking and an understanding of how design impacts activation, conversion, monetization, and retention. Ability to design complex product experiences involving AI models, generation states, usage costs, asynchronous processes, and other non-standard UX patterns. Basic visual identity and branding skills, including logo, typography, and color systems. Strong collaboration skills and experience working closely with engineers, including the ability to balance UX quality with technical constraints. Ukrainian for internal communication. English at B1 level or higher. Would be a plus: Experience designing generative AI products or interfaces built on top of third-party AI models. Experience launching a new product or major feature from scratch, rather than primarily iterating on an established product. Flutter-first experience or close collaboration with Flutter engineering teams. Experience with web-first products and custom checkout flows outside of the App Store. Experience designing subscriptions, tokens, credits, or other usage-based monetization models. Experience designing performance marketing landing pages and conversion-focused acquisition experiences. Experience working in a startup or pre-PMF environment, where you’re comfortable with ambiguity, fast iteration, and changing priorities.
