Your role

You own how fonio feels on the web. Our website is our most important storefront — and right now it's not where it needs to be. You don't build one nice page, you build a system: a design system and landing page templates that roll out into localized pages across 9+ markets. Continuous optimization, not a one-off redesign. You design and ship - you own the build end-to-end, not a handoff to engineering. We're building an AI operating system for SMBs - people should feel that on the website.

What to expect

• You own the design and continuous optimization of our website and landing pages

• You build a scalable design system with reusable components

• You develop landing page templates that localize across all markets (DACH, FR, IT, ES, UK, PL, US, and more)

• You design and ship live yourself - full ownership from concept to published page

• You think in user journey, conversion, and responsive design

• You work closely with the Creative Director on brand direction

Who we're looking for

• Several years of experience as a UI/UX or web designer focused on converting websites (portfolio required)

• You think in systems and components, not individual pages

• You build and ship yourself

• Experience with design systems and localization across multiple markets

• You understand conversion and think in journeys

• German at native level + good English

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 at the Vienna office (plus all the drinks you want, and yes, we have protein bars and vitamins too).

• Relocation bonus (if you still need to move to Vienna)

• Equipment of your choice - whatever makes you happy.

• Regular team offsites.

Hiring process

• 15 min intro call

• 30 min skill interview

• 20 min culture fit with the founders
