Are you passionate about AI & renewable energy?

This is a full-time, on-site position based in Berlin.
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+ 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.
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.
