Security, Privacy & Data Governance :
- Protect sensitive HR information through robust roles, groups, ACLs, COE security, data segregation, encryption, auditability, and access-review support.
- Follow privacy, retention, compliance, and records-management requirements for employee data and integration payloads.
- Partner with HR, security, risk, architecture, and platform teams to document controls, exceptions, and remediation actions.
Delivery & Stakeholder Collaboration :
- Work with HR product owners, business analysts, architects, engineering teams, vendors, and system owners to refine requirements and deliver end-to-end solutions.
- Produce technical designs, data mappings, sequence flows, configuration documentation, test evidence, release plans, runbooks, and knowledge articles.
- Participate in Agile ceremonies, estimation, backlog refinement, demonstrations, UAT support, deployment, hypercare, and production support.
- Mentor developers, review designs and code, and serve as a technical escalation point for HRSD and integration defects.
Required Experience & Skills :

- Strong knowledge of HR Case Management, HR Services, COEs, Lifecycle Events, Employee Center or HR portals, HR knowledge, service catalog, Flow Designer, and HR security.
