Job description:

Experience - 7-10 years

Role: Senior Python Developer

Health Data Engineer – Data Nexus Platform

What You'll Build

• Hospital data integration pipelines: Extract consented patient EHR data from European hospitals → pseudonymize → standardize to OMOP CDM

• OMOP CDM transformation logic: Map hospital diagnosis codes (ICD-10), lab results (LOINC), medications to OMOP standardized vocabularies (SNOMED-CT)

• Data quality validation framework: Implement 16-dimension data quality checks ensuring data completeness, accuracy, and regulatory compliance for FDA/EMA submissions

• Master data management (MPI): Patient identity resolution, entity matching, and deduplication across multiple hospital systems

• Clinical domain pipelines: Build ETL workflows for 8+ clinical domains including diagnoses, medications, lab results, procedures, clinical assessments, and biomarkers

• Regulatory-grade validation: Prove lossless transformation, maintain audit trails, and ensure GxP compliance for pharmaceutical regulatory submissions

Required Experience

• Healthcare Domain Expertise (Non-Negotiable)

• 5+ years working with hospital EMR/EHR systems (EPIC, Cerner, or similar)

• Hands-on OMOP CDM experience: Mapping hospital data to OMOP Common Data Model (PERSON, VISIT_OCCURRENCE, CONDITION_OCCURRENCE, DRUG_EXPOSURE, MEASUREMENT, etc.)

• Clinical coding systems: Deep familiarity with ICD-10, SNOMED-CT, and LOINC

• Master Data Management (MPI): Patient identity resolution, entity matching, deduplication, golden record creation

• Healthcare data standards: Working knowledge of HL7, FHIR, or EDI

• Real-world hospital data complexity: Understanding of incomplete records, coding variations, longitudinal patient journeys, and clinical workflows

Technical Skills

• Python + SQL: Advanced proficiency for ETL development, data transformation, and validation logic

• Data pipeline development: Building scalable, maintainable ETL/ELT workflows (pandas, PySpark, or similar)

• Data quality frameworks: Schema validation, referential integrity checks, reconciliation logic, null handling, data profiling

• Cloud platforms: Experience with cloud data infrastructure (AWS, GCP, Azure, or Oracle Cloud)

• Version control: Git-based development workflows

• Regulatory & Compliance Knowledge

• GxP awareness (preferred): Basic understanding of regulatory data requirements for pharmaceutical submissions

• Data governance: Lineage tracking, metadata management, audit trail documentation

Preferred Background

• Academic health informatics or biomedical informatics training

• Experience with oncology, immunology, or clinical research datasets

• Exposure to clinical trials data or pharmaceutical research

• Knowledge of European hospital systems or GDPR compliance

• Experience with data orchestration tools (Airflow, Azure Data Factory, etc.)

What We're NOT Looking For

• Generic data engineers with only cloud platform experience

• Candidates who've only worked with clean, structured datasets

• ETL developers without healthcare domain knowledge

• Architects who talk conceptually but lack hands-on coding experience

Day-to-Day Responsibilities

• Write Python/SQL code to transform hospital EHR data into OMOP CDM format

• Map clinical codes (ICD-10 → SNOMED-CT, local lab codes → LOINC) using standardized vocabularies

• Implement data quality validation logic proving 100% data integrity for regulatory submissions

• Build patient identity resolution workflows across multiple hospital data sources

• Debug complex data quality issues in real-world hospital datasets (missing values, coding inconsistencies, schema variations)

• Document transformation logic, data lineage, and validation rules for audit compliance

• Collaborate with hospital partners to understand clinical workflows and data structures

• Support pharmaceutical clients in understanding data quality and OMOP standardization
