SAP Integration Architect

About the role We are looking for an SAP Integration Architect to own how Finto connects to SAP. Some of our customers run their finance operations on SAP, and no two landscapes look alike: R/3, ECC and S/4HANA, on-premise and cloud, Business One and Business ByDesign. You'll design how master data, invoices and postings move between those systems and our AI platform, and turn what starts as a bespoke integration into a product that goes live in weeks. This is a hands-on role, working directly with our CTO and the founding team: you'll set the architecture, write code, and sit across the table from customer IT. You're the first hire dedicated to SAP at Finto and you define what the practice becomes. We're headquartered in Munich, with roots in San Francisco through Y Combinator. What you'll do Own the end-to-end architecture from a customer's SAP system into Finto: master data, invoices, postings, write-back. Choose the integration path per SAP flavour - OData, IDoc, BAPI/RFC, BTP/CPI, file-based - and make that choice repeatable instead of re-deciding it per customer. Build the connector platform: templates, validation, monitoring, and the tooling that makes every new landscape faster than the last. Translate FI and MM process knowledge into specifications and field mappings our engineers build against. Ship production code with the engineering team - same repo, same reviews, Node.js and TypeScript. Be the SAP authority in the room: with customer IT, with their integration p
