Key responsibilities include: • Designing and leading the development of scalable data pipelines and ETL processes using Snowflake and Matillion and/or other integration tools. • Optimizing and troubleshooting complex data workflows to ensure high performance, data integrity, and reliability. • Architecting data ingestion from diverse external sources and ensuring efficient movement from source to target systems. • Managing third-party integrations and overseeing the ingestion of data from new practice acquisitions into the EDW. • Implementing and enforcing data governance, privacy, and security best practices to protect sensitive healthcare data. • Providing technical leadership through code reviews, testing, and documentation to uphold high standards of data engineering. Education: Bachelor's degree in computer science, related IT systems program of study, or alternate program with equivalent IT related experience. Technical Experience • 8+ years of progressive experience in data engineering, with a strong focus on healthcare data systems, compliance, and interoperability. • Expert-level proficiency in Snowflake and Matillion (or other similar tools) for designing, developing, and optimizing complex data integration and transformation workflows. • Advanced SQL skills with demonstrated experience in performance tuning, data modeling (star/snowflake schemas), and relational database design. • Hands-on experience with cloud platforms (AWS, Azure, GCP), including cloud-native data services, cost optimization, and infrastructure-as-code practices. • 5+ years of Python development, including deep familiarity with libraries such as NumPy, Pandas, and Snowflake Connector for Python SDK. Skilled in building scalable data transformation pipelines using Jupyter Notebooks and Azure SDK. • Extensive experience with Git-based source control systems (GitHub, Azure DevOps, GitLab), including branching strategies, pull request reviews, and CI/CD integration. • Proficient in developing data integrations from disparate sources using VS Code and GitHub, with a focus on modular, reusable code and robust error handling. • Expert at translating source-to-target mapping (STM) documentation into robust data pipelines. • Strong knowledge of healthcare data governance, privacy, and compliance standards (HIPAA, HITECH), with experience implementing secure data access controls. • Exceptional problem-solving skills, with a track record of resolving complex data issues and optimizing performance across large-scale systems. • Strong communication and collaboration abilities, with experience working cross-functionally with data architects, analysts, and business stakeholders. Industry Specific Experience • Led the development of complex financial data integrations and schema mappings from legacy systems to modern reporting platforms. Demonstrated advanced understanding of period-based accounting data, including charge reconciliation, refunds, payments, and voids, ensuring accurate financial balances across systems. • Architected and implemented medical data integrations from disparate sources into standardized reporting schemas. Applied deep domain expertise in healthcare data, including periods of care, CPT/HCPCS codes, encounter types, service dates, insurance hierarchies (primary/secondary), payment structures, and provider/location attribution. • Designed scalable frameworks for onboarding new data sources, including acquisitions, with automated validation and transformation logic to maintain data integrity and consistency. Preferred Qualifications: • 5+ years of hands-on experience with the Snowflake cloud data platform, including performance optimization, advanced SQL features, and data sharing capabilities. • 7+ years of experience using VS Code integrated with Git-based source control systems (e.g., GitHub, Azure DevOps), including CI/CD workflows, branching strategies, and code review best practices. • 7+ years of experience developing scalable data pipelines using Python and Pandas, with expertise in loading, transforming, and validating financial and medical datasets in cloud-based relational databases. • Extensive experience working in Agile environments, contributing to sprint planning, backlog grooming, and cross-functional collaboration with product owners, data architects, and analysts. • Demonstrated ability to lead technical initiatives, mentor junior engineers, and contribute to architectural decisions and data strategy.
