  • Creates clear source-to-target data mappings that align legacy inspection and correction data to the new data model, schema and ingestion requirements for a modernized database environment.
  • Works closely with business stakeholders, application teams, database administrators, data engineers and project teams to validate data definitions, resolve mapping questions and ensure data meaning is preserved during conversion.

  • Develops and maintains detailed documentation, including data dictionaries, table inventories, mapping workbooks, schema alignment notes, conversion assumptions and open data issues.
  • Supports data conversion planning, mock loads, validation activities and issue resolution to help ensure inspection and correction data is accurately prepared for ingestion into the new database.
  • Works independently with strong attention to detail and follows through on complex data research assignments with minimal guidance.
  • Acts as a knowledgeable resource for project team members by explaining source-system data structures, data lineage, table relationships and conversion impacts.
Job Requirements:
  • Requires a bachelor's degree in computer science, information systems, data management, engineering, mathematics, business technology or a related field, or equivalent experience.
  • Typically five or more years of experience working with databases, data analysis, data mapping, data conversion, schema analysis or application data support.
  • Experience analyzing relational databases and writing SQL queries to research tables, fields, joins, dependencies and data quality issues.
  • Experience creating source-to-target mapping documentation, data dictionaries, table inventories or conversion specifications.
  • Experience working across multiple business systems or legacy applications to understand data lineage, operational processes and system-of-record decisions.
  • Preferred experience with inspection, correction, asset management, work management, field operations or utility data.
  • Preferred experience with Microsoft SQL Server, Oracle, cloud databases, data integration tools or reporting/query tools.

Job Competencies:
  • Advanced attention to detail and ability to work accurately with complex data across multiple systems.

  • Ability to understand business processes and translate operational rules into data requirements, mapping logic and validation criteria.
  • Strong documentation skills, including the ability to maintain data dictionaries, mapping workbooks, table inventories, issue logs and assumptions.
  • Strong collaboration skills and ability to work effectively with business users, database administrators, developers, data engineers, testers and project stakeholders.
  • Strong communication skills, including the ability to explain technical data findings in a clear, practical way for both technical and nontechnical audiences.
