Founding Product Designer

About the Role

A Y Combinator-backed AI creative tools startup is looking for a Founding Product Designer to join their small, fast-moving team in Berlin. This is a founders-level role where your design decisions will directly shape product adoption, user experience, and growth. You'll own design end-to-end — from early concepts to pixel-perfect execution — and help define what it means to make powerful AI-driven creative tools accessible to everyone.

What You'll Do

  • Partner closely with engineering to design intuitive, AI-native interfaces that balance simplicity with power.
  • Create experiences that hide complexity while giving users meaningful control when they need it.
  • Run continuous user interviews and usability tests to surface opportunities and validate design decisions.
  • Own the full design lifecycle: prototypes, design systems, and pixel-perfect UI delivery.
  • Drive growth through design experiments, onboarding improvements, and conversion optimisation.
  • Shape go-to-market visuals and messaging that resonate with the target audience.

What We're Looking For

  • 5+ years of product design experience, ideally with AI-powered or complex software interfaces.
  • Strong proficiency in Figma and modern prototyping workflows.
  • Demonstrated experience building and maintaining scalable design systems.
  • A portfolio showcasing end-to-end product design — from concept to launch — including design systems and polished UI.
  • Experience designing onboarding flows and running experiments to improve activation and conversion metrics.
  • Comfortable partnering with engineering and contributing to product strategy in an early-stage, ambiguous environment.
  • Experience conducting user research (interviews, usability testing) and translating insights into actionable design decisions.
  • Entrepreneurial mindset — you thrive without roadmaps and take full ownership of outcomes.

Location

This role is on-site in Berlin, Germany. Candidates must be based in Berlin or willing to relocate. Visa sponsorship is not available.

Compensation & Benefits

  • Salary range: €80,000 – €160,000 annually, depending on experience.
  • Early-stage equity and the opportunity to grow into a senior design leader as the company scales.
