Job description

About fonio

We grew from $1M to $10M ARR in under 12 months and now serve 10,000+ customers. fonio is Europe's market leader for AI phone agents for SMBs. Our AI answers every call automatically, but voice is just the beginning: we're building the AI operating system for small businesses. We move fast, take ownership, give direct feedback, and avoid politics and unnecessary meetings. Join one of Europe's fastest-growing companies.

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
  • Turn complex functionality into simple and easy to use experiences
  • 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

  • At least 5 years of experience in product design, 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.

Hiring process

  • 15 min intro call
  • Case study
  • Skill interview with Moritz
  • Culture call with the founders

Why work at fonio

  • Rapid Growth & Impact: The company is in a phase of hypergrowth (40% MoM), and employees are "still early enough that your work will genuinely shape the culture, the product, and the company." fonio.ai/en/careers
  • Culture: Described as fast, committed, and in-office by default. The team emphasizes moving fast and having fun. Most roles are Vienna-based, with the expectation of being in the office most days.
  • Remote Options: Engineering roles are fully remote (within ±3 hours of CET). For other roles, there is a temporary relocation to Vienna for onboarding (1-3 months), followed by relocation to the target market.
  • Relocation Support: The company sponsors travel and accommodation in Vienna for the onboarding period and offers full relocation support for moving to target markets.
  • Team Size: Around 40-50 people, with plans to double by the end of the year.
  • Hiring Process: A 3-4 step process: 15-minute intro call, 30-45 minute skills interview (sometimes with a case study), potentially a deeper skills or leadership interview, and a final 20-minute culture call with both founders. fonio.ai/en/careers
