What we’d love you to do (and love doing)

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.

API-Led Connectivity

Expose and consume OData and REST APIs from SAP backends. Secure, throttle, and monitor APIs centrally using SAP API Management. Leverage SAP Graph as a unified semantic layer to simplify multi-system data access.

Event-Driven Architecture

Design and implement real-time, event-driven integrations using SAP Event Mesh and Advanced Event Mesh. Migrate batch-based integrations to event-driven patterns where appropriate. Architect reliable event flows with guaranteed delivery, deduplication, and error handling.

Non-SAP & SaaS Integrations

Build integrations with non-SAP SaaS applications using pre-built adapters and Open Connectors. Handle data model mapping across heterogeneous systems without custom code where possible.

Operations & Quality

Own the production health of your integrations — monitoring, alerting, SLOs, and incident response. Conduct and participate in code and design reviews. Ensure integrations meet GDPR, security, and compliance requirements.

Collaboration & Mentorship

Work autonomously and act as a trusted, reliable team member. Share knowledge and support colleagues through pairing and hands-on guidance. Collaborate with Product Management and stakeholders to clarify requirements and surface trade-offs early.

We’d love to meet you if

Hands-on experience with SAP BTP Integration Suite. Proficiency with SAP Business Accelerator Hub — deploying and configuring pre-built integration content. Strong experience with SAP API Management — API policies, security, throttling, monitoring. Experience designing and implementing event-driven architectures using SAP Event Mesh or Advanced Event Mesh. Solid understanding of OData, REST, SOAP, and messaging protocols (AMQP, Kafka, or equivalent). Experience integrating SAP systems (S/4HANA, SuccessFactors, Ariba) with third-party SaaS platforms. Knowledge of GDPR and security best practices in integration design.

Nice to Have

Experience with SAP Graph. Familiarity with SAP S/4HANA data models and standard APIs. Experience migrating from SAP PI/PO to BTP Integration Suite. Knowledge of OpenAPI / AsyncAPI specification. Experience with CI/CD for BTP-based integration artefacts.
