The Role

You make sure that as a Head of Finance, you own the entire finance operation behind one of fastest-growing companies, across our entities in Europe and the Americas.

What to Expect

• 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 You Bring

Must-haves

• 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.

Nice-to-haves

• Experience with post-merger integration or investor due diligence.

What We Offer

• Up to €150,000
• Equity
• Relocation support
• Daily lunch and dinner
• Equipment of your choice
• Regular team off-sites
• On-site in Vienna, working directly with the core-team
