• Monitors infrastructure costs, resource utilization, and performance; identifies and implements optimization opportunities.
• Supports the deployment of C-BRAIN AI tools on cloud-based platforms; coordinates with technical teams on infrastructure requirements.
• Ensures all data handling complies with DUA terms and applicable PHI de-identification requirements; implements, documents, and maintains de-identification workflows for each incoming dataset.
• Uploads curated datasets to ADDI/AD Workbench and other designated repositories (NIAGADS, GP2, or equivalent) as directed; manages access controls within the platform to ensure data is accessible only by authorized users and tools.

Data Harmonization and Quality

• Develops and implements data harmonization procedures to integrate datasets from multiple sources (NACC, ADNI, consortium member contributions) into a unified, analysis-ready format.
• Implements data quality validation checks at ingestion and transformation stages; documents data quality issues and coordinates resolution with data providers.
• Maintains comprehensive data lineage documentation: tracks data from source to consumption, documents all transformations, and ensures reproducibility.
• Collaborates with research scientists and the AD, Scientific to understand scientific data requirements and ensures data products meet research use case specifications.
• Aligns incoming datasets to established biomedical data standards including AD Workbench, ADDI, NIAGADS, and GP2; builds and maintains data dictionaries and metadata records for each ingested dataset.

DUA Technical Support and Data Delivery

• Provides technical input on Data Use Agreements: defines technical specifications for data format, delivery method, transfer protocols, and storage requirements in coordination with the Senior Technical Product Manager.
• Confirms receipt of contributed datasets, validates format and completeness against DUA specifications, and logs acceptance in the DUA register.
• Flags data quality, completeness, or format issues to the Senior Technical Product Manager and CTO for follow-up with data contributors.
• Supports technical aspects of the data delivery monitoring process: tracks expected deliveries, confirms receipt, and maintains data delivery logs.
• Supports beta testing of data ingestion tools and provides structured feedback to development partners; maintains clear, reproducible documentation so pipeline processes can be audited and transferred.

Documentation and Reporting

• Maintains comprehensive technical documentation for all pipelines, infrastructure configurations, and data architecture decisions in the C-BRAIN documentation repository.
• Develops and maintains a C-BRAIN data catalog: documents available datasets, data dictionaries, lineage, and access procedures.
• Contributes technical content to C-BRAIN progress reports, Steering Committee materials, and grants reporting as requested by the CTO or Senior Technical Product Manager.
