Data Analyst L5 to L10 - Deadline 03/09/26

• Data extraction, mapping and integration: Extract, map, transform and integrate data from a range of large and very large data sources available within TAXUD, including, among others, Surveillance, TARIC, EORI, EBTI and ICS2, as well as relevant European Commission and external sources such as COMEXT and COMTRADE. Make the resulting data available in the appropriate analytical environments for further analysis and modelling.

• Data processing and preparation: Design and implement efficient data-processing solutions for large volumes of data, taking into account the technical constraints and specific characteristics of the available analytical architectures and environments, including DataLab, ICS2/SSA and Power BI SNC.

• Analytical visualisation and reporting: Create analytical products, reports, dashboards and clear and informative visualizations to communicate complex data findings to stakeholders using the available platforms and technologies, including Power BI SNC, Dataiku and Python, with a focus on supporting the analytical needs of the relevant stakeholders.

• Integration and deployment of analytical solutions: Provide technical support for the deployment, integration, orchestration and configuration of analytical models and solutions within SSA, PowerBI SNC or temporary local solutions. Support the integration of such solutions into the relevant analytical workflows and environments.

• Data Analysis and Modelling: Conduct exploratory data analysis, build predictive models, and extract insights from large datasets; Develop and implement machine learning algorithms to optimize customs risk assessment; Design or participate in the design of data processing algorithms for specific use cases.

• Technical/User documentation: Produce and maintain comprehensive technical documentation covering the procedures for accessing, querying, extracting, transforming and making data available for analytical purposes. Documentation shall be structured and sufficiently detailed to enable peer review, knowledge transfer, maintenance and reproducibility by other members of the team, thereby ensuring continuity of the services.

• Analytics, architecture and governance optimisation: Identify and propose improvements to analytical solutions, data architectures, data governance arrangements and related business processes. Proposals shall take into account the need to support multidisciplinary collaboration between Member States' customs experts and the Commission, within the applicable legal, security and governance framework, and shall cover both permanent and ad-hoc analytical use cases.

• Machine learning and analytical experimentation: Support experimentation and further development of analytical capabilities, within the SSA platform where relevant, including the investigation, testing and evaluation of new approaches, machine-learning and deep-learning techniques, data-science methodologies and relevant software libraries and technologies, in cooperation with Member States where appropriate.

• Other activities: Other tasks assigned by the direct manager
