The role spans the full data lifecycle: ingesting data from diverse operational systems, curating it within scalable data lakes and warehouses, and delivering high-quality, model-ready datasets to analysts, data scientists, and AI/ML workflows. This role blends hands-on data platform engineering with database and reporting expertise.Responsibilities include:Design, build, and maintain scalable data lakes, warehouses, and lakehouse environments (on-premises and/or cloud) to consolidate data from diverse enterprise sources.Develop and orchestrate reliable, automated ETL/ELT pipelines to ingest, transform, and deliver structured and unstructured data.Implement layered data architectures (e.g., raw / curated / consumption or bronze / silver / gold layers) that support reuse across reporting, analytics, and AI workloads.Monitor and maintain pipelines proactively to ensure high availability, timeliness, and data freshness.Apply data quality, validation, and error-handling practices to ensure accuracy, completeness, and consistency.Establish and maintain data lineage, cataloging, and metadata to support governance and traceability.Collaborate with data scientists and ML practitioners to curate, prepare, and serve high-quality datasets for model training, fine-tuning, and inference.Build and maintain pipelines that transform raw enterprise data into clean, model-ready datasets.Support feature engineering, feature stores, and reusable data products for AI/ML use cases.Enable AI-oriented data patterns such as embedding pipelines and retrieval-augmented workflows, and support integration with vector stores where appropriate.Partner with engineering teams to operationalize data workflows that keep models supplied with reliable, well-governed data.Administer, monitor, and maintain relational database environments (on-premises and/or cloud).Perform and automate routine operations, including: backups and restores (full, differential, and log), integrity checks and consistency validation, index maintenance and statistics updates.Monitor and troubleshoot performance issues, including CPU, memory, and I/O bottlenecks, as well as blocking, deadlocks, and long-running queries.Implement performance tuning strategies such as query optimization, execution plan analysis, and index design and review.Manage database availability and resilience, including high availability, clustering, and disaster recovery planning and validation.Coordinate patching, upgrades, and service releases.Ensure security and compliance through access controls, permissions, encryption, auditing, and vulnerability mitigation.Support scheduled jobs, ETL processes, and automated data workflows.Write efficient queries and transformations for reporting and analytical workloads.Reduce dataset size and improve refresh and processing performance.Understand and optimize the impact of joins, filters, and aggregations across large datasets.Translate business questions into queries, metrics, and visualizations.Develop, maintain, and optimize dashboards and reports using leading BI tools (e.g., Tableau, Power BI, or comparable platforms).Design semantic models and data sources for reporting, including fact/dimension modeling (star and snowflake schemas), data shaping, and transformation.Optimize report performance through query tuning and data model optimization (aggregations and relationships).Participate actively in group and cross-functional meetings.Deliver clear, coherent report-outs to senior management.Work with interdepartmental groups to innovate and improve the
