About the Role
As a Senior Software Engineer specialising in SAP Integrations, you will be a core member of our in-house ERP Engineering team, responsible for designing, building, and operating modern integration solutions across our SAP S/4HANA landscape. You will work exclusively with modern cloud integration and API-led connectivity — no legacy point-to-point middleware. You will own integration solutions end-to-end: from design and development through to production operation, monitoring, and continuous improvement. You will collaborate closely with Product Management, platform teams, and external stakeholders to deliver integrations that are performant, scalable, and compliant.
What We'd Love You to Do
ERP Engineering is part of the Zalando Technology Foundation, which builds and operates Zalando's core business platform. Our team owns the ERP landscape, integrating SAP S/4HANA tightly with internal platforms and external partners. We work at pace, value technical excellence, and take full ownership of what we ship.
Design & Delivery
•Design, build, and operate scalable cloud-native integration solutions on SAP BTP Integration Suite — connecting SAP systems (S/4HANA, SuccessFactors, Ariba) and third-party platforms (Salesforce, Workday, ServiceNow) using API-led connectivity, pre-built iFlows, and event-driven patterns via SAP Event Mesh
•Own production health end-to-end — monitoring, alerting, SLOs, incident response — while ensuring all integrations meet GDPR, security, and compliance requirements
•Collaborate closely with Product Management and stakeholders to clarify requirements, share knowledge across the team, and ship high-quality, maintainable integration flows in small, safe iterations
