Founding Product Engineer (Design + Frontend)

WhyHireWrong?

Build a personal AI agent from first concept to shipped product. You will own product design and frontend implementation across web and iOS, working directly with the founder and a small technical team in Warsaw. This 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.

Responsibilities

  • The product is not fully specified, so you will make product decisions, test quickly, and ship working versions.
  • 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: 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.
  • 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.

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.
  • 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.
  • Availability to work on-site in Warsaw five days per week.
  • Nice to have SwiftUI experience.
  • Experience designing AI, agent, automation, or workflow products.

Preferred

  • Vercel AI SDK or AI Gateway experience.

Benefits

  • Fluent Polish for daily team communication.
