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.
