Drive the definition and evolution of KPIs, data products, and analytical capabilities as part of a service-oriented data platform.
Data Warehouse Architecture & Solution Design:
Development and ownership of the end-to-end data warehouse architecture, defining scalable structures, data models, and integration patterns aligned with business strategy.
Design, govern, and continuously optimize logical and physical data models, leveraging AI capabilities to enhance data quality, consistency, automation, and trusted data assets across the enterprise platform.
Acting as the architectural authority for data solutions, evaluating new technologies and shaping the long-term data ecosystem.
Data Integration & Processing Frameworks:
Design and oversee robust, scalable data integration frameworks (ETL/ELT), ensuring efficient, reliable, and maintainable data pipelines.
Multi-Platform Integration: Design and govern integration patterns that allow decentralized teams (using e.g., Apache/Open Source tools) to contribute to and benefit from the group-wide OneLake environment.
Guide development teams in implementing best practices for data ingestion, transformation, and orchestration across diverse source systems.
Cross-Functional Collaboration:
Collaborate closely with group wide business units, analysts, data engineers and IT teams to ensure seamless data flow and alignment between architecture and implementation.
Act as a key interface between business and technology, ensuring solutions are both technically sound and business-relevant.
Data Governance, Security & Compliance:
Establish, implement, and continuously develop the governance framework, standards, and operating principles for data governance, security, and compliance across the data platform.
Federated Governance: Implement a "Hub and Spoke" governance model that balances group-level standards with the necessary local autonomy for our international business units.
Ensure data is managed as a strategic business asset through clear ownership models, end-to-end lineage, robust quality controls, and effective stewardship practices that support trusted decision-making and operational excellence.
Drive governance processes and controls that secure regulatory compliance, reduce risk, and ensure consistent, high-quality data and reliable data operations across the organization.
AI & Advanced Analytics Enablement:
Define and drive the integration of AI and machine learning capabilities within the data platform, ensuring the data warehouse supports scalable and production-ready AI use cases.
Collaborate with data science and analytics teams to design architectures that enable model development, deployment, and monitoring.
Ensure data readiness for AI (e.g., feature engineering, data quality, lineage, and governance) and promote reuse through standardized data products and feature stores.
Performance, Scalability & Continuous Improvement:
Architect and continuously optimize the platform for performance, scalability, and cost-efficiency in line with growing data volumes and usage.
Drive continuous improvement of data services, enabling a modern, flexible, and high-performing data warehouse ecosystem.

Ability to gather, analyze, and translate complex business requirements into technical data solutions, supported by strong presentation and communication skills to clearly convey ideas, recommendations, and outcomes to both technical and business stakeholders.
Strong experience in designing, developing, and maintaining data warehouses and data marts.
Proven expertise in data modeling (e.g. dimensional modeling, star/snowflake schemas) and database design principles.
Proficiency in SQL and experience with various database technologies: Strong hands-on experience with cloud data warehouses, specifically Microsoft Fabric (OneLake, Direct Lake, Mirroring), Snowflake, or BigQuery.
Advanced Data Integration: Expertise in building ETL/ELT pipelines with Python and Azure Data Factory, with a specific understanding of how to bridge Open Source (Apache Airflow/Spark) and Microsoft ecosystems.
Strong analytical, problem-solving, and critical thinking skills.
Excellent communication and teamwork skills in English.
Valued experience:
Familiarity with cloud data platforms (Azure / GCP) is highly valued.
BI Tool Knowledge: Strong familiarity with modern BI platforms such as Power BI is an advantage. Also experience with QlikView/Qlik Sense is considered a significant advantage, particularly in understanding and migrating embedded business logic.
Master’s degree in a relevant field.
Expectations for succeeding in this role:
You possess the ability to think strategically about long-term data architecture goals while also maintaining a hands-on approach to operational excellence in data pipeline development and problem-solving.
