About the role

Key responsibilities & impact

Build HDL data files with awareness of business object hierarchy, loading Person, Work Relationship, Assignment, Employment, and dependent objects in the correct sequence across in-scope HCM modules
Design source-to-target field mapping with transformation logic, code conversion tables, and source data-quality resolution
Execute data loads in development and test environments
Read HDL output logs, distinguish validation errors from import errors, and resolve failures at root cause
Perform data reconciliation at every mock cycle, including source-versus-Oracle row counts, field-level spot checks, and business-rule validation using Oracle-side OTBI reports
Build and maintain source-to-target mapping tables, transformation rules, load run logs, error-resolution notes, and mock-run sign-off reports

Requirements

What you’ll need

2–3 years of Oracle HCM or HR system data migration experience with hands-on HDL execution — has submitted HDL files, read the error output, and resolved failures independently
Working knowledge of the Oracle HCM worker data model: Person, WorkRelationship, Assignment, and their load dependency sequence
Proficiency in Excel for data transformation, field mapping, and code conversion; SQL or Python is an advantage
Systematic error resolution approach — does not re-submit a failed load until the root cause is confirmed and corrected
Data reconciliation discipline — treats row count and field value validation as mandatory, not optional
Oracle Fusion Cloud Applications HCM Process Essentials certified — preferred
Oracle Global Human Resources Cloud Implementation Professional — preferred
Python or SQL proficiency for automated transformation scripts and post-load reconciliation queries — preferred
Experience migrating from a prior HCM platform such as PeopleSoft, Oracle EBS HRMS, or Workday — preferred
Data documentation discipline — produces mapping documents, load run logs, and reconciliation reports
Root-cause mindset
Cross-team collaboration with functional, security, and cutover workstreams
Ability to explain HDL error messages and data quality requirements to non-technical HR data owners
Ability to adapt to new module objects and data structures across implementations
Personal accountability for data accuracy at each mock cycle
