• Collaborate with data engineering and cloud infrastructure teams to architect performant, cost-effective data flows connecting operational systems, data lakes, and AI services.
• Design context-retrieval mechanisms and semantic overlays that ground Large Language Models (LLMs) and predictive models in validated enterprise and product lifecycle data.
• Work closely with domain specialists, analytics engineers, and AI practitioners to standardize business metrics and taxonomies, accelerating the enterprise transition toward AI-augmented operations. What do you bring?
• Degree in Computer Science, Data Science, Information Systems, Software Engineering, or a related technical field.

• Hands-on experience developing enterprise semantic models and interactive dashboards in Power BI, with a clear understanding of DAX, data modeling, and enterprise reporting architectures.
• Working knowledge of modern AI/ML concepts, including Retrieval-Augmented Generation (RAG), vector databases, semantic search, or knowledge graphs (such as RDF, OWL, Neo4j, or graph traversal techniques) (nice-to-have).
• Demonstrated experience in data modeling methodologies (dimensional modeling, semantic layers, data vault) and CI/CD best practices for data (version control with Git, automated testing with dbt).
• Experience or strong interest in industrial data domains, IoT telemetry, or Product Lifecycle Management (PLM) systems is a plus.
• Ability to act as a bridge between traditional data analytics teams and cutting-edge AI development teams.
• Excellent communication skills with fluency in English.
