Grant Thornton is seeking Data Analyst, Data Migration Senior Associate to join the team in Downers Grove, IL.

We are seeking a highly analytical and detail-oriented Data Analyst with extensive data migration experience to support enterprise transformation initiatives, including ERP implementations and system modernization programs.

Key Responsibilities

Data Analysis and Data Quality

  • Analyze source-system data to identify completeness, accuracy, consistency, duplication, and missing-value issues.
  • Define and execute data cleansing, remediation, and enrichment activities before migration.
  • Develop and maintain data-quality metrics and validation reports.

Data Mapping and Transformation

  • Develop and maintain source-to-target mapping specifications for master, transactional, and reference data.
  • Define business rules, transformation logic, and data-conversion requirements.
  • Partner with business subject matter experts to validate field definitions and update mapping specifications as business processes evolve.

Data Migration Execution

  • Support migration activities for ERP, financial, operational, and reporting systems.
  • Review migration files and templates for load readiness.
  • Collaborate with technical teams to troubleshoot data-conversion issues and load failures.
  • Participate in mock loads, test migrations, cutover planning, and production deployments.

Reconciliation and Testing

  • Validate migrated data through source-to-target reconciliation, System Integration Testing, User Acceptance Testing, and post-production review.
  • Investigate reconciliation discrepancies and identify the root causes of migration defects.
  • Develop reconciliation reports and controls to support business review and sign-off.

Stakeholder Collaboration

  • Coordinate migration activities across business owners, functional consultants, developers, project managers, and data migration consultants.
  • Facilitate data-discovery workshops and requirements-gathering sessions.
  • Communicate migration risks, issues, and dependencies to project leadership.
  • Recommend improvements to data-quality controls, governance practices, and migration procedures.

Required Qualifications

  • Bachelor’s degree in Information Systems, Computer Science, Data Analytics, Finance, Accounting, Business, or a related field.
  • Five or more years of experience as a Data Analyst, Business Analyst, or Data Migration Analyst, including at least three years supporting large-scale data migration projects.
  • Strong knowledge of data mapping, transformation, reconciliation, and validation methodologies.
  • Advanced SQL skills with the ability to analyze and manipulate large datasets.
  • Experience working with SAP S/4HANA, Oracle, Dayshape, Fieldglass, Microsoft Dynamics, or comparable platforms.
  • Proficiency with Excel, Power BI, Tableau, or comparable reporting tools.
  • Excellent analytical, problem-solving, and communication skills.

Preferred Qualifications

  • Experience supporting SAP S/4HANA Public Cloud data migration projects.
  • Knowledge of financial, billing, project accounting, customer, vendor, and master data structures.
  • Experience with ETL and data-integration tools.
  • Familiarity with Snowflake, Azure Data Factory, Informatica, SAP Migration Cockpit, or comparable technologies.
  • Understanding of data governance, controls, and audit requirements.
  • PMP, CBAP, SAP, or data-management certification preferred.
