• Purposeful Projects – Improve systems that serve real people by delivering smarter data, streamlined processes, and strategic insight.
• People-First Culture – We’re as committed to your growth as we are to delivering high-impact solutions. You’ll find support, autonomy, and community here.
• Strategic, Hands-On Work – From data architecture and documentation to client workshops and solution delivery, you’ll influence every step of the process.
• Collaborative Trust – Our clients rely on us to listen carefully, deliver consistently, and guide wisely. We partner with integrity, curiosity, and heart.

What You’ll Do

Working closely with data architects, ETL/data engineers, BI developers, DBAs, and business subject matter experts, the Senior Health Data Modeler ensures data structures are scalable, standards-compliant, well-documented, and aligned to enterprise and regulatory requirements across the Health and Human Services ecosystem.

Data Architecture & Strategy

• Develop and deliver long-term strategic goals for data architecture vision and standards in conjunction with data users, clients, and other key stakeholders.
• Lead data architecture, data modeling, and data movement initiatives to enhance the data warehouse supporting analytics for Medicaid, Medicare, and Commercial healthcare data — including domains such as claims, provider, TPL, and member information subject areas.
• Create an end-to-end vision for how logical design translates into one or more physical databases and how data flows through successive stages.
• Document data architecture and the enterprise environment to maintain a current, accurate view that supports a single version of the truth and scales to future analytical needs.

Data Modeling & Design

• Analyze and translate business needs into long-term solution data models; evaluate existing data systems and work with the development team to create conceptual data models and data flows.
• Design and maintain conceptual, logical, and physical data models across staging, integration, and semantic/presentation layers.
• Develop dimensional models (Kimball star/snowflake), normalized (OLTP/3NF), OLAP, and Data Vault patterns; implement Slowly Changing Dimensions, role-playing dimensions, dimensional hierarchies, surrogate keys, and data classification.
• Define primary/foreign keys, indexes, partitioning, constraints, and referential integrity rules to ensure data quality and performance.
• Produce and maintain entity-relationship diagrams (ERDs), data flow diagrams, and model documentation using Erwin or equivalent tools.

Governance, Quality & Compliance

• Ensure data strategies and architectures are in regulatory compliance; identify where existing policies and procedures require change or where new ones are needed.
• Oversee the mapping of data sources, data movement, interfaces, and analytics with the goal of ensuring data quality.
• Create and maintain data model and metadata policies and procedures for functional design; maintain data dictionaries, business glossaries, and lineage documentation.
• Support classification and protection of sensitive data (PII, PHI) in alignment with HIPAA, PHI, and SOX requirements.

Collaboration & Delivery

• Provide technical recommendations and engage with ETL Architects, Business SMEs, and other stakeholders throughout the Solution/Data Architecture and implementation lifecycle to develop high-performance, highly scalable data solutions (data marts/warehouse, data mining, and advanced analytics).
• Address data-related problems regarding systems integration, compatibility, and multiple-platform integration.
• Develop and implement key components and testing criteria to guarantee the fidelity and performance of data architecture.
• Communicate with the customer and project team in a timely manner and elevate issues and risks appropriately.

Modernization & Migration Support

• Contribute to migration of legacy Teradata models to modern cloud platforms (Azure Synapse / Databricks Lakehouse, Snowflake).
• Design target-state models leveraging medallion (Bronze/Silver/Gold) architecture, Delta Lake, and Parquet patterns.
• Assess existing models for modernization opportunities, redundancy, and optimization; recommend improvements to architects.

Requirements

• Strong problem-solving, influencing, communication, and presentation skills; self-starter.
• 7+ years of Experience in data modeling, data strategy, and roadmap for large and complex health entities and systems; implemented large-scale, end-to-end Data Management & Analytics solutions for more than one large client.
• 5+ years of Strong knowledge of regulatory security requirements regarding HIPAA, PHI, PII, and other healthcare data security standards.
• 5+ years of Experience with Erwin Data Model (or comparable tools such as ER/Studio, SQL Developer Data Modeler).
• 5+ years of strong healthcare domain knowledge of Medicaid, Medicare, and Commercial healthcare data sets.
• Expertise with normalized OLTP, OLAP, MDM, and dimensional modeling techniques — star schemas, slowly changing dimensions, role-playing dimensions, dimensional hierarchies, and data classification.
<
• 5+ years of Expert-level SQL skills with direct experience writing complex analytic queries, stored procedures, DDL, DML, and DCL; thorough knowledge of query optimization and the ability to write to ANSI standards and review others’ code.
• 5+ years of experience in Data Quality, Data Profiling, Data Governance, Data Security, Metadata Management, MDM, Data Archival, and Data Migration strategies using appropriate tools.
• Demonstrated ability to work in a fast-paced, changing environment with short deadlines, interruptions, and multiple concurrent tasks/projects.
