YOUR ROLE
You shape how fonio feels to use for thousands of businesses. You own core areas of our product end-to-end: from talking to customers, to designing the flow, to shipping it with our engineers.
You're a hands-on designer with high craft and a lot of autonomy. You don't wait for perfect specs. You find the problem, design the solution and move fast.
WHAT TO EXPECT
- Own the design of core product areas end-to-end, in close collaboration with Product Engineering and our founders
- Talk to customers regularly and turn insights into design decisions
- Make complex functionality simple: solve complexity instead of designing it visibly
- Shape and scale our product design system
- Prototype fast with AI tools (Cursor, v0, Claude and others) to get from idea to testable flow in hours, not weeks
- Use analytics to measure what works, and iterate
WHO WE'RE LOOKING FOR
- Several years of experience as a product designer, ideally in a small, fast-moving product team (portfolio required)
- Exceptional design craft: interaction detail, hierarchy, typography and motion
- High autonomy: you take ownership without needing much structure
- Experience with design systems and shipping features end-to-end
- Product and analytics thinking: you don't design from your gut, you measure
- AI-first mindset
- Fluent English (any additional language is a plus, especially German (DACH is our most important market)
WHAT WE OFFER
- Competitive salary: €65,000–€90,000
- Equity - you're building this, so you should own a piece of it.
- Food & drinks - lunch and dinner are on us
- Relocation bonus (if you still need to move)
- Equipment of your choice - whatever makes you happy.
