Why This Role Stands Out

This Product Designer role offers a unique opportunity to shape an AI-powered operating system at the intersection of technology and sustainability, ideal for a mid-senior designer with a strong portfolio who thrives in purposeful, fast-paced environments. You'll have significant impact by setting the UX/UI bar and reinventing user experiences, making this a fantastic chance to grow your skills with a reputable company.

Job Description

Are you passionate about AI & renewable energy?

Do you thrive in fast-paced, hard-working and purpose-driven environments? If you're ready to use your skills to help leveraging our product to the next level and keep processes smooth, then look no further - we want YOU!


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.
