Staff Solution Architect – Finance Systems (m/f/d)

Do you want to be the architect who can look at a payment moving through half a dozen systems and know exactly how it should work? At SIXT, every payment we take, worldwide, has to clear correctly: through our own systems, several payment providers, and on into invoicing, dunning, and the ledger behind it. As we take on new payment methods and bigger migrations, we need a senior architect who can hold that whole picture in view. If you've built payment or financial-transaction platforms before, we'd love to meet you at our Pullach headquarters, near Munich. Apply now!

• You share architectural ownership of SIXT's payment platform, not carry it alone. It's grown fast this past year alone: a payment method with a settlement lifecycle stretching over weeks and a mobile-wallet integration deep inside our PCI-secured zone
• You report directly to our Division Engineering Manager for Finance, a direct seat at the table on architecture decisions, not a role several layers removed from where they get made, working alongside about 40 engineers in six teams spread across multiple countries
• Every new use case is a cross-channel, cross-system flow: a payment might start at a counter, in the app, or on the web, and your design follows it through refunds, disputes, and reconciliation. You carry that same ownership into our multi-year migrations: the franchise business coming onto the platform, a decade-old legacy core being retired, and invoices that now split more ways than before
• You use AI as a genuine lever, not a checkbox, leaning on the in-house agentic toolkit we've built for payment investigations and design reviews to stress-test integration decisions before they get expensive to unwind
• You stay hands-on where it matters: writing RFCs and reference implementations, prototyping to de-risk a design, and reviewing the load-bearing code, on a stack of Java, Spring Boot, Kafka, PostgreSQL, Temporal, AWS, and Kubernetes
• You raise the design bar across the platform, pairing with staff engineers and engineering managers on their toughest calls, and leaving each of them more confident to own the next big one themselves
