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. Now we’re expanding globally and into new products. We move fast, take ownership, give direct feedback, and avoid politics and unnecessary meetings. Join one of Europe’s fastest-growing companies.

Your Role

As Head of Finance, you own the entire finance operation behind one of Europe's fastest-growing companies, across our entities in Europe and the US.

  • Own accounting for all entities: pre-accounting in-house, full ownership of our accounting stack, and the transition to fully in-house accounting in 2027.
  • Run controlling: month-end, quarterly and annual closings, revenue reporting down to the invoice line item, cost and profit center reporting.
  • Own tax: VAT and sales tax, employment tax and contributions, international tax, and transfer pricing between entities.
  • Own cash flow and treasury: planning, forecasting, cash reserves, return optimization, intercompany transfers and FX.
  • Roll out a lean ERP and turn everything manual in finance into workflows and AI agents.
  • Build and lead the finance team, starting with your first hire shortly after you join.
  • Work directly with both founders and the extended leadership team.

What We Offer

  • Up to €130,000 + equity package.
  • On-site in Vienna, relocation package if needed.
  • Real ownership from day one
  • Everything you need to be successful. If you need it, you get it.

What You Bring

  • You were part of building a finance in a fast-growing company, internationally, across different jurisdictions and accounting regulations. (ideally: VC-backed B2B SaaS/Tech)
  • You have run closings and accounting prep yourself, not just reviewed them.
  • You are experienced across controlling, tax, cash flow and treasury.
  • Workflows, agents and automations are your default, not the exception. Claude Code, n8n and similar tools are part of your toolkit.
  • Obsession with detail: small errors bother you before they bother anyone else.
  • Perfect German, very good English.

Hiring process

  • 15 min Intro Call
  • 15 min Intro Call with our Chief of Staff
  • 45 min Skill Interview & Case Study Discussion
  • On-Site Meeting in Vienna
  • 20 min 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
