You will own product design and frontend implementation across web and iOS, working directly with the founder and a small technical team in Warsaw.\nThis is a 0-to-1 role. You will define how users interact with an AI agent, design the product experience, and build the interfaces yourself. The product is not fully specified, so you will make product decisions, test quickly, and ship working versions.\nResponsibilities\nTranslate early ideas into user flows, prototypes, and high-fidelity Figma designs.\n\nImplement production web interfaces with TypeScript, React, and Next.js.\n\nDesign and build interfaces that make agent behavior understandable: what the agent is doing, what input it needs, what it has done, and what requires user approval.\n\nDefine flows for starting tasks, reviewing agent actions, correcting mistakes, and approving sensitive actions.\n\nContribute to the iOS app using SwiftUI.\n\nEstablish the first component library, interaction patterns, visual system, and frontend conventions.\n\nHandle real product states: loading, empty states, errors, partial results, unclear AI output, and long-running actions.\n\nWork with the founder and engineers on product decisions, technical trade-offs, and shipping priorities.\n\nRequirements\nProduction experience shipping TypeScript, React, and Next.js applications.\n\nStrong product design ability in Figma, including user flows and high-fidelity UI.\n\nAt least one shipped product or feature where you owned both design and frontend implementation.\n\nAbility to move independently from an unclear idea to a tested, working interface.\n\nSolid frontend fundamentals: component architecture, responsive layout, accessibility, API state handling, and performance.\n\nExperience making product decisions rather than only implementing tickets or finished designs.\n\nA portfolio, live product, or code sample that clearly shows your design and engineering contribution.\n\nFluent Polish for daily team communication.\n\nAvailability to work on-site in Warsaw five days per week.\n\nNice to have\nSwiftUI experience.\n\nVercel AI SDK or AI Gateway experience.\n\nExperience designing AI, agent, automation, or workflow products.","description_format":"text","description_chars":2223,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Polish","level":"Advanced
