This is a strong fit for someone who understands both the technical and functional sides of data migration and can help ensure NetSuite, UKG, and related system data is accurate, complete, and ready for a successful go-live.

Key Responsibilities Data Assessment & Analysis

Analyze source systems, legacy data structures, extracts, and target system requirements to identify data gaps, quality issues, inconsistencies, duplicates, missing values, and transformation needs. Assess NetSuite, UKG, payroll, HR, ERP, finance, employee, organizational, and related integration data to support migration and implementation readiness. Work with business and technical stakeholders to understand current-state data, target-state requirements, field usage, business rules, and data ownership.

Define data cleansing rules, transformation logic, validation criteria, migration requirements, and data readiness checkpoints. Support discovery sessions, data workshops, mapping reviews, and requirements discussions with business stakeholders and implementation partners. Cleanse and prepare data files for migration, testing, integration, and cutover activities.

Data Loading & Migration Execution

Support the extraction, transformation, loading, and validation of clean data files into target systems. Build, run, or support data scripts, templates, load files, and transformation processes required for the data loading process. Work with implementation partners and IT teams to coordinate test loads, production loads, file transfers, and cloud-based import/export activities. Support data migration activities across ERP, HRIS, payroll, workforce management, benefits, finance, and related integration workstreams.

Validation, Reconciliation & Testing

Identify and resolve transformation errors, failed loads, rejected records, data mismatches, and reconciliation issues. Support UAT test data loads, system integration testing, end-to-end testing, payroll validation, cutover planning, and go-live readiness. Produce data migration reports, error files, reconciliation reports, issue logs, and data-quality tracking documentation as required.

Vendor & Stakeholder Coordination

Work closely with third-party implementation partners, vendors, project managers, business stakeholders, and IT teams to support migration planning and execution. Track data-related risks, issues, dependencies, mapping gaps, load defects, and outstanding decisions. Support project planning activities related to test cycles, data readiness, cutover, go-live, and post-go-live support. Escalate data quality, migration, or integration concerns to the project manager and relevant stakeholders.

Required Skills Minimum 4 years of data migration, data integration, data conversion, or data analysis experience.
