Preferred Qualifications: * Experience working with healthcare interoperability standards and message formats, particularly HL7 v2 and FHIR. * Familiarity with clinical terminology and code systems such as SNOMED CT, ICD-10, LOINC, RxNorm, or CPT. * Experience supporting large-scale EHR data conversion or migration efforts, particularly between RPMS and Oracle Health/Cerner-or a comparable legacy-to-modern EHR migration. * Understanding of clinical data mapping, terminology normalization, provenance, and validation across source and target systems General personal traits we know will connect well with the team: * Dependable, self-directed, and able to meet commitments. * Comfortable learning new subject areas and solving unfamiliar problems. * Enjoys collaborating across technical and subject-matter disciplines. * Pragmatic and able to select the appropriate tool for the requirement. ## Description ATA is seeking a Data Scientist to support data pipeline development, validation, and analysis within a cloud-based Health IT data platform. This role is hands-on and delivery-focused, with an emphasis on building reliable, reproducible data workflows using SQL, Python, and PySpark in an Azure Synapse environment., Data Pipeline Development * Develop, maintain, and optimize data pipelines using SQL, Python (pandas), and PySpark. ATA, LLC | 752 Walker Road | Suite D | Great Falls, VA 22066 | www.ata-llc.com Advanced Technology Applications * Execute and manage notebook-based workflows within Azure Synapse, including debugging and documentation. * Process and transform structured and semi-structured data in formats such as CSV, JSON/NDJSON, and Parquet. * Work within ETL/ELT pipelines across raw, curated, and production data layers. * Ingest, profile, map, and transform healthcare data from EHR systems and interface feeds while preserving source lineage and clinical context Data Quality and Validation * Perform structured data validation, including row counts, null checks, duplicate detection, schema validation, and allowed value enforcement. * Identify and resolve data quality issues such as schema drift, inconsistencies, and transformation errors across pipeline stages. * Apply repeatable testing and validation practices, including reproducing issues, verifying fixes, and ensuring data reliability prior to downstream use. * Validate source-to-target mappings and reconcile records across source and destination systems during data conversion and migration activities. Data Analysis and Dataset Development * Conduct exploratory data analysis to identify patterns, anomalies, and data quality concerns. * Develop derived datasets to support reporting, analytics, and downstream data use cases. * Collaborate with stakeholders to translate data requirements into usable datasets and metrics. Data Modeling and Structure Awareness * Interpret and work with data schemas, including column definitions, data types, primary and composite keys, and table relationships. * Manage dataset grain and understand how join strategies (e.g., one-to-one vs. one-to many) impact row counts and outputs. Debugging and Troubleshooting * Trace data issues from source ingestion through transformation logic to final outputs. * Use logs and debugging approaches to diagnose and resolve pipeline issues. * Document data transformations, assumptions, mappings, and validation results in a clear and consistent manner. * Collaborate with engineers, analysts, and stakeholders to ensure data usability, integrity, and alignment with requirements.
