- Conduct security assessments, vulnerability analyses, and compliance reviews to identify gaps, risks, and migration challenges.
- Develop and maintain detailed migration plans covering planning, conversion, implementation, validation, and cutover activities.
- Lead and execute complex migrations from TSS or ACF2 to RACF while minimizing production disruption and downtime.
- Configure, implement, validate, and integrate RACF within IBM z/OS environments based on application, security, and compliance requirements.
- Migrate RACF profiles, rules, permissions, resource classes, and access controls to replace legacy security configurations.
- Use IBM zSecure and other RACF utilities to analyze security environments, automate RACF command generation, and streamline migration activities.
- Collaborate with system programmers, network engineers, application owners, database teams, and other technical stakeholders to ensure successful RACF integration.
- Troubleshoot migration issues and provide post-migration support, tuning, validation, and optimization.
- Serve as a subject matter expert on RACF administration, z/OS security architecture, migration, security management, and compliance.
- Develop and deliver training sessions and workshops covering RACF administration, mainframe security practices, and operational procedures.
- Evaluate opportunities to apply AI technologies to RACF security monitoring, analysis, automation, and operational efficiency.
- Document migration procedures, security configurations, technical decisions, operational processes, and lessons learned.
- Support knowledge transfer and help strengthen the capabilities of client and internal technical teams.
Requirements
- 8+ years of experience in IBM z/OS mainframe security, including significant hands-on RACF experience.
- Demonstrated experience leading or supporting complex migrations from CA Top Secret (TSS) and/or CA ACF2 to IBM RACF.
- Expert-level knowledge of IBM RACF, z/OS security, security administration, and mainframe security concepts.
- Strong hands-on knowledge of RACF profiles, resource classes, access controls, permissions, and security configuration.
- Experience using IBM zSecure and other RACF security utilities to analyze, automate, and validate migration activities.
- Proven experience conducting security assessments and analyzing TSS/ACF2 environments before migration.
- Demonstrated ability to develop and execute end-to-end security migration strategies, conversion plans, implementation procedures, and cutover plans.
- Experience configuring RACF and integrating security controls with mainframe applications, databases, system software, and infrastructure.
- Strong troubleshooting, analytical, and problem-solving capabilities, with the ability to manage complex technical issues independently.
- Foundational knowledge of PL/I, Assembler, REXX, and Java.
- Interest in artificial intelligence and its potential applications in mainframe security monitoring and automation.
