About The Position

CACI is seeking an HCM Data Migration Middleware Developer to support a large-scale federal HCM modernization program. This transformational initiative will deploy Oracle Fusion Cloud HCM as the unified human capital management platform for approximately federal civilian employees across numerous agencies. In this role, you will design, build, and maintain the ETL pipelines and middleware that transform legacy HR data extracted from agency source systems into Oracle Fusion HCM Data Loader (HDL) and HCM Spreadsheet Data Loader (HSDL) formats for loading into the target platform. You will process agency migrations ranging from small agencies with 10,000 employees to extra-large large federal agencies, building scalable data transformation pipelines with robust error handling, data cleansing, and reconciliation capabilities. Your work will directly determine the data quality and migration success for every agency transitioning to the new Oracle Fusion Cloud HCM platform. This is a primarily remote position with up to 10% travel. This position is at the T4 (senior) level, suited for an experienced technical professional who operates with significant independence, resolves complex technical challenges using advanced techniques, and provides guidance and mentorship to less experienced team members.

Requirements

Bachelor's degree in Computer Science, Information Technology, Software Engineering, or related field
6+ years of experience in ETL development, middleware development, or data integration for enterprise system implementations
5+ years of hands-on experience with ETL/middleware tools such as Oracle Integration Cloud (OIC), Informatica PowerCenter/Cloud, Talend, or equivalent data integration platforms
Strong SQL proficiency with experience writing complex transformation queries, data validation scripts, and reconciliation procedures
Experience with batch data processing for large-volume datasets (100,000+ records) including performance optimization, error handling, and restart/recovery design patterns
Knowledge of data quality management principles including data profiling, cleansing, standardization, and validation
Experience with file-based data integration formats (CSV, XML, JSON) and enterprise data loader specifications
Familiarity with Agile/SAFe development methodologies and iterative delivery practices
Must be able to obtain and maintain a Public Trust clearance (US Citizenship required)
Additional experience may substitute for degree

Nice To Haves

6+ years of ETL/middleware development experience with specific experience on HCM or ERP data migration projects

Responsibilities

Design and develop ETL pipelines using Oracle Integration Cloud (OIC), Informatica, Talend, or equivalent middleware tools to transform extracted legacy HR data into Oracle Fusion HCM HDL and HSDL load file formats
Build data transformation rules that map legacy data values (codes, descriptions, hierarchies) to Oracle Fusion HCM reference data, value sets, and lookup values for each agency migration
Develop data cleansing pipelines that identify and remediate data quality issues including missing required fields, invalid date formats, duplicate records, and referential integrity violations before target system loading
Design and implement batch processing frameworks capable of handling large-volume agency migrations ranging from small to very large agency employee populations with configurable parallelism and restart/recovery capabilities
Build comprehensive error handling and exception management within ETL pipelines including error categorization, automated retry logic, and error reporting dashboards for migration teams
Develop data reconciliation processes that compare source record counts, key data element values, and business rule validations between legacy extracts, transformation outputs, and target system loaded records
Create and maintain data quality dashboards providing real-time visibility into migration pipeline status, error rates, data completeness metrics, and reconciliation results for each agency migration wave
Design reusable transformation templates and parameterized mapping configurations that accelerate successive agency migrations by leveraging patterns from completed migrations
Collaborate with legacy system export developers (PeopleSoft/EBS team) to define extraction file formats, handoff procedures, and data interface specifications
Support iterative mock migration cycles (typically 3-4 per agency) and final cutover data loads, optimizing pipeline performance and resolving data quality issues identified in each cycle
Document ETL design specifications, transformation rules, data flow diagrams, and operational runbooks for each agency migration in accordance with SAFe Agile artifact standards
Operate with significant independence to analyze and resolve complex functional and technical issues, applying advanced techniques and serving as a go-to technical resource and mentor for less experienced team members across the program
Lead small work efforts and technical initiatives within the assigned functional area, contributing to team strategy, conducting technical reviews of deliverables, and guiding junior consultants on Oracle Fusion Cloud HCM best practices and solution approaches
