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.
