Adservio Luxembourg
Adservio Luxembourg is the Luxembourg arm of Adservio Group — 300+ consultants across Paris, Brussels and Luxembourg, 15 years serving regulated industries. We opened in Luxembourg in 2022 and work across financial services, energy and utilities, transport and mobility, insurance and the public sector. You join our Technologies & Engineering team.

The context
With our team, you work for an international organisation in the defence sector, based in Luxembourg. Its logistics, procurement and operations generate data that decision-makers rely on, in a security-classified environment where data quality, traceability and access control are not negotiable.

• Model data warehouses and data marts that answer the organisation's reporting needs

Deliver the insight

• Build dashboards and reports with business users, from first mock-up to production
• Translate business questions into indicators with clear, documented definitions

Govern and secure the data

• Apply data quality controls, lineage and documentation so that every figure can be explained
• Enforce access rules and security requirements specific to classified information

Your profile
What is essential

• At least 5 years in data engineering or business intelligence, delivered in production
• A valid NATO SECRET security clearance, or a dormant clearance that can be reactivated
• Advanced SQL and hands-on experience with SQL Server and its ETL and reporting tools (SSIS, SSRS)
• Proven delivery of dashboards with Power BI or an equivalent BI tool
• A degree in computer science, data science or engineering

What makes the difference

• Python for data processing and automation
• Experience with data governance or data quality frameworks
