About The Position

Build a personal AI agent from first concept to shipped product. This 0-to-1 role owns product design and frontend implementation across web and iOS, working directly with the founder and a small technical team in Warsaw. The product is not fully specified, so the engineer will make product decisions, test quickly, and ship working versions. The role defines how users interact with the AI agent, designs the product experience, and builds the interfaces.

Requirements

• Production experience shipping TypeScript, React, and Next.js applications.
• Strong product design ability in Figma, including user flows and high-fidelity UI.
• At least one shipped product or feature where you owned both design and frontend implementation.
• Ability to move independently from an unclear idea to a tested, working interface.
• Solid frontend fundamentals, including component architecture, responsive layout, accessibility, API state handling, and performance.
• Experience making product decisions rather than only implementing tickets or finished designs.
• A portfolio, live product, or code sample that clearly shows your design and engineering contribution.
• Fluent Polish for daily team communication.
• Availability to work on-site in Warsaw five days per week.

Nice To Haves

• SwiftUI experience.
• Vercel AI SDK or AI Gateway experience.
• Experience designing AI, agent, automation, or workflow products.

Responsibilities

• Translate early ideas into user flows, prototypes, and high-fidelity Figma designs.
• Implement production web interfaces with TypeScript, React, and Next.js.
• Design and build interfaces that make agent behavior understandable, including what the agent is doing, what input it needs, what it has done, and what requires user approval.
• Define flows for starting tasks, reviewing agent actions, correcting mistakes, and approving sensitive actions.
• Contribute to the iOS app using SwiftUI.
• Establish the first component library, interaction patterns, visual system, and frontend conventions.
• Handle product states including loading, empty states, errors, partial results, unclear AI output, and long-running actions.
• Work with the founder and engineers on product decisions, technical trade-offs, and shipping priorities.
