Senior UKG Integration Engineer

Randstad is seeking a highly skilled Senior UKG ProWFM Integration Engineer for a high-impact, long-term engagement with a premier client in the Washington, D.C. area. In this critical technical role, you will serve as the primary architect and support lead for the complex data ecosystem connecting UKG Pro Workforce Management (ProWFM) with SAP HR, Payroll, and Finance modules. You will be responsible for the end-to-end lifecycle of integrations—from initial design and Dell Boomi development to rigorous SAP finance posting validation—ensuring that time, attendance, and pay rules flow seamlessly across enterprise systems for a large, unionized workforce.

Key Responsibilities

• Integration Development: Design, build, and maintain sophisticated interfaces using Dell Boomi (AtomSphere) and Workforce Integration Manager (WIM) to sync data between UKG ProWFM and downstream payroll/finance systems.
• System Configuration: Expertly configure UKG ProWFM building blocks, including Pay Rules, Work Rules, Accruals, Absence Management, and complex scheduling requirements.
• Cross-Functional Orchestration: Lead the technical integration between ProWFM and SAP (HR, Payroll, and Finance), specifically managing the critical "payroll-to-finance" posting processes.
• Testing & Validation: Own end-to-end testing cycles, including regression testing and data reconciliation, to ensure financial accuracy and compliance with enterprise controls.
• Technical Troubleshooting: Perform deep-dive root cause analysis using SQL for data validation and resolve defects tracked in JIRA.
• Stakeholder Communication: Bridge the gap between technical and non-technical teams by documenting data flows, interface control documents (ICDs), and operational runbooks.

Qualifications & Experience

• Professional Experience: Minimum of 5+ years of hands-on technical experience with UKG ProWFM (formerly Workforce Central) and Dell Boomi.
• Technical Mastery: Proven expertise in WIM, SQL, and various integration protocols including APIs (REST), SFTP, and file-based exchanges (CSV, XML).
• ERP Knowledge: Demonstrated experience integrating UKG with SAP environments, with a specific focus on financial posting and payroll synchronization.
• Complex Environments: Background supporting large-scale, highly regulated enterprises, ideally with experience managing unionized workgroups or operations-focused labor (e.g., Yardmasters).
• Education: Bachelor’s degree in Computer Science, Information Technology, Systems Engineering, or a related field.
• Soft Skills: Exceptional analytical skills and the ability to manage multiple concurrent projects independently while maintaining strict adherence to change management protocols.
