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.
