Job 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.
A core expectation of this role is the ability to work across the full data lifecycle, from ingestion through transformation to final dataset delivery, while maintaining data quality and traceability. The ideal candidate is comfortable debugging data issues end-to-end, understands how data structure and join logic impact outputs, and applies disciplined validation and documentation practices. This role also supports exploratory data analysis and the development of derived datasets to enable analytics and downstream use cases. The position will work extensively with healthcare data originating from EHR systems and interface feeds, including HL7 v2 and FHIR data, clinical terminology, and source-to-target data mappings.
Key Responsibilities:
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 |
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.
ATA, LLC | 752 Walker Road | Suite D | Great Falls, VA 22066 |
Advanced Technology Applications
Communicate data issues, findings, and workflow updates with technical team
members.
Minimum Qualifications:
Hands-on experience writing SQL queries for data transformation and analysis.
Experience using Python (e.g., pandas) for data processing.
Hands-on experience using PySpark for distributed data processing.
Experience working within cloud-based data platforms, preferably Azure Synapse or
similar.
Understanding ETL/ELT concepts and data pipeline architecture.
Experience working with structured and semi-structured data formats (CSV, JSON,
Parquet).
Familiarity with Git and collaborative development workflows.
Strong problem-solving and debugging skills across data pipelines.
Ability to validate and ensure data quality through structured checks and testing
practices.
Strong written and verbal communication skills.
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.
