About this role

ECS is seeking a Data Scientist to work remotely. 

This role bridges data science and data architecture. The person will map data
sources and relationships, build and maintain a company-wide data dictionary,
and support the Enterprise Architect in applying policy, standards, and business
logic to the overall data framework. 

Key Responsibilities 

1. Data Mapping 
Identify, trace, and document how data flows across systems — from source to
destination — including transformations, dependencies, and ownership. 
2. Data Dictionary Development 
Build and maintain a comprehensive data dictionary defining every field, its
meaning, format, source, and business context, so teams have one consistent
reference. 
3. Architecture Support 
Work closely with the Enterprise Architect to translate data mapping and
dictionary findings into the technical architecture, ensuring data models
reflect real business logic and policy requirements. 
4. Data Quality & Standards 
Analyze data for consistency, accuracy, and completeness. Flag gaps or
conflicts between systems and recommend standardization. 
5. Business Logic Validation 
Partner with business stakeholders (HR, Finance, Operations, etc.) to
confirm that documented business rules match how data is actually defined
and used. 
6. Governance Collaboration 
Support data governance efforts by aligning the data dictionary and mapping
work with company policy, compliance needs, and access control
requirements. 
7. Documentation & Reporting 
Create clear, maintainable documentation (data lineage diagrams, dictionary
entries, mapping reports) that both technical and non-technical teams can
use. 

Salary Range: $120,000 - $130,000
