    Your role in the team

    • The Senior BW / Data Expert is a senior technical specialist in the target team and plays a critical role in understanding, stabilizing, simplifying, and modernizing the existing SAP BW-based reporting and data environment.
    • The role combines technical depth with solution design responsibility and acts as the main expert for legacy assessment, future-state data design, and technically sound implementation decisions.
    • Diese Rolle ist besonders wichtig in einem Kontext, in dem die aktuelle Landschaft möglicherweise benutzerdefinierte Logik, historische Komplexität, sich überschneidende Datenschichten, nicht transparente Routinen und unzureichende Dokumentation enthält.
    • Der Senior BW / Data Expert wird erwartet, die aktuelle Umgebung zu reverse-engineeren, zu bewerten und zu verbessern, während er den Migrationspfad zur zukünftigen Plattformarchitektur mitgestaltet.
    • The individual will have a significant impact on the technical quality of the future platform, the realism of migration decisions, and the avoidance of technical dead ends.
    • The role is therefore critical not only for development execution but also for ensuring that the transformation is practical, supportable, and economically sensible.
    • Co-design a sustainable and scalable Finance Data Platform (Change).
    • Assess the existing SAP BW landscape (data models, transformations, process chains, routines, queries, etc.) and pinpoint technical debt, redundancy, and performance bottlenecks.
    • Leiten Sie das technische Design von BW-Remediation, Vereinfachung und Modernisierungsarbeiten.
    • Decide what to retain, refactor, migrate, or decommission, and shape the path toward the target architecture (SAP Datasphere / BDC).
    • Design robust, well-documented data models and transformation logic, including optimization of the existing setup using best practices.
    • Establish a monitoring process for data flows for accuracy and completeness.
    • Design and implement data quality checks and cleansing processes.
    • Überwachen Sie den Datenlebenszyklus der Finance Data Platform (Run).
    • Own technical documentation of key objects, dependencies, and data lineage.
    • Lead root-cause analysis for complex defects, performance issues, and reconciliation breaks, with actionable insights.
    • Support the Finance team with ad-hoc data analysis and troubleshooting.
    • Advise the Team Lead on feasibility, effort, dependencies, and risk for backlog items; mentor more junior team members.
    • Actively apply AI and automation to improve platform standards, development principles, and coding quality.
