Jr Finance Manager (f/m/d) – AP | AI-first Finance

We're hiring: AP & Treasury Specialist (f/m/x) Arbio is a fast-growing short-term rental and property management group operating 16 legal entities across Germany, Austria and the UK (9 DE, 5 AT, 2 UK), with more entities being onboarded. Our finance function runs real volume across multiple banks, currencies and tools — and we're building it into something that scales without scaling headcount. We're looking for someone to own the money-in-motion side of that: accounts payable, spend management and day-to-day treasury. 2–4 years in accounts payable, treasury or finance operations, ideally in a multi-entity or high-volume environment Hands-on bookkeeping experience — you can independently book and reconcile creditor accounts in DATEV; this is a core requirement, not a nice-to-have Solid grasp of German accounting and compliance (DATEV/DUO, GoBD, SEPA, VAT basics, city/accommodation tax) Experience with spend management and banking platforms (Moss, Qonto or similar) and strong Excel skills Sharp attention to detail, ownership mindset, and the ability to prioritise under deadline pressure A process-improvement instinct — you spot manual, repetitive work and want to streamline it Real interest in AI-powered automation (AI-assisted coding, reconciliation, Moss and similar tools) — you'd rather build an agent than maintain a spreadsheet Fluent German and English The full AP cycle, end to end — invoice processing and coding in Moss through complete creditor bookkeeping and reconciliation in DATEV; this ledger is yours, no hand-off to Accounting Payment runs released together with a second approver as a four-eyes check — you code and prepare, someone else releases Real room to build — you don't just run the process, you get to redesign it: automating coding, reconciliation and payment prep with AI tools instead of repeating the same manual steps every month Cash, always in view — daily liquidity across every entity and bank account, with enough foresight that nothing catches us off guard The full payment cycle in motion — supplier payments, landlord and owner payouts, payroll transfers, tax payments, ad-hoc funding Bank relationships and account setup — you're the one the banks call A clean close every month — accruals, reconciliations, and books that hold up under any audit City/accommodation tax across DE & AT, handled end to end, not chased down last-minute A standing bridge to Accounting — you own the ledger, they spot-check it, no duplicate work Real impact, not AI theater.
