Senior Software Engineer – SAP Integrations (all genders)

THE ROLE & THE TEAM

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 (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.

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.
