What You Will Do

Design the AI-Powered OS : Shape the interface and experience of the AI-powered operating system installers worldwide will run their business on.

Design with a Product Lens : Go beyond the brief to understand why it matters, balancing user needs and business impact with craft and polish.

Set the UX/UI Bar : Maintain a high bar for UX/UI design that's intuitive, accessible, and genuinely delightful across every surface of the product.

Redesign and Reinvent : Improve existing flows and interfaces, and design new ones from scratch, prototyping and iterating quickly to maximize value.

Challenge and Collaborate : Push back on ideas that don't meet that bar, and work closely with product and engineering to raise UX quality across the board.

What Makes You a Great Fit

A strong portfolio demonstrating end-to-end product thinking — from discovery to execution — with high-quality craft and problem-solving.

2–3 years of experience as a product/UX designer, ideally in a startup or product-driven environment.

Strong product sense and comfort in ambiguity: you make trade-offs that balance user and business impact, focus on outcomes over output, and iterate quickly and autonomously in a startup environment.

Growth & UX understanding: solid grasp of digital funnels, onboarding and conversion journeys; strong with both quantitative data (A/B tests, funnel metrics) and qualitative data (user research, feedback); track record of using that to grow feature adoption, activation, and retention.

Ability to leverage AI tools to speed up concepting and prototyping.

Clear communicator: you translate requirements for developers and product, backed by real empathy for the user and a keen eye for design.

very good communication abilities in English and German (Bonus: You also speak Italian, French, and/or Portuguese)

Even if you don’t meet every requirement, we encourage you to apply! Imposter syndrome shouldn't hold you back - we value talent and passion above all.
