Building and configuring the systems sits with the engineering teams (no hands-on SAP or coding expertise required). * Stakeholder management across Finance, Tax, Legal, and engineering. * Fluent English; German an advantage. Important: * Functional understanding of invoice processing, tax determination, and fiscal compliance requirements. * Integration mindset: comfortable reasoning across system boundaries to keep a specialized, business-critical flow reliable. Nice to have: * Experience with e-invoicing or fiscalization platforms (e.g. PEPPOL, SAP DRC) or country-specific mandates (Italy SDI, France e-invoicing, SAF-T) * Experience with order management systems (e.g. IBM Sterling or comparable) * Experience with middleware or integration platforms (e.g. SAP CPI, MuleSoft, Kafka) * Exposure to high-volume transaction systems ## Description * Own FISCAS within Customer Fulfilment: a focused, specialized application that turns ERP billing data into legally and fiscally compliant invoices for every customer sales order, across channels and markets. * Run and optimize the module in live operation (it is largely rolled out), keeping invoice generation accurate and stable while adapting it to evolving country-specific fiscal and e-invoicing regulations. * Own the data flows through the module: billing data in from ERP and order management, compliant documents out to fiscalization and e-invoicing services, tax engines, archiving, and reporting, including asynchronous processing and failure handling. * Translate regulatory and business requirements into product requirements together with Tax, Finance, and Legal, ensuring order, pricing, tax, and accounting data map into country-compliant invoices. * Align interfaces, contracts, and changes with the adjacent product teams (ERP, order management, finance, reporting). * Own the backlog with engineering (user stories, API contracts, data models, acceptance criteria), prioritize against regulatory deadlines and operational stability, and track KPIs: invoice accuracy, processing latency, integration stability, compliance rates. ## Related Videos - [Why make use of an integration platform in today's software developments and infrastructure?](https://www.wearedevelopers.com/videos/758-why-make-use-of-an-integration-platform-in-today-s-software-developments-and-infrastructure) - [Developer’s Perspective: Overview of the Tezos Blockchain Ecosystem](https://www.wearedevelopers.com/videos/237-developer-s-perspective-overview-of-the-tezos-blockchain-ecosystem) - [How to Benchmark Your Apache Kafka](https://www.wearedevelopers.com/videos/76-how-to-benchmark-your-apache-kafka) - [Next Level Enterprise Architecture: Modular, Flexible, Scalable, Multichannel and AI-Ready?](https://www.wearedevelopers.com/videos/1017-next-level-enterprise-architecture-modular-flexible-scalable-multichannel-and-ai-ready) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [A Guide To Functional Programming](https://www.wearedevelopers.com/videos/408-a-guide-to-functional-programming) ## Related Articles - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [Spanish Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/353-spanish-business-culture-and-etiquette) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [System change: restart as developer?](https://www.wearedevelopers.com/magazine/39-system-change-restart-as-developer) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where to Find German Tech Jobs](https://www.wearedevelopers.com/magazine/366-where-to-find-german-tech-jobs)
