Requirements

At least 10 years of hands-on Db2 for z/OS engineering, administration, architecture, performance tuning, recovery, and production support in large enterprise Sysplex and data-sharing environments.
Experience with a DB2 V13 upgrade and the ability to discuss DSNZPARM recommendations, software deployment, and backout considerations.
Strong background in Db2 security setup and administration.
Expert knowledge of Db2 for z/OS subsystem internals, including IRLM, DDF, EDM pools, buffer pools, logging, utilities, packages, plans, WLM interactions, and z/OS dependencies.
Proven experience configuring, governing, and tuning DSNZPARM settings across development, test, and production environments.
Experience supporting Db2 data-sharing groups, including group buffer pools, coupling facilities, member balancing, lock contention, restart and recovery, high availability, and disaster recovery.
Strong understanding of Db2 security architecture, including RACF integration, authentication, authorization, trusted contexts, privileged-access controls, SECADM/SYSADM separation, audit traces, encryption, certificates, and secure remote connectivity.
Experience with Db2 software lifecycle management, including SMP/E, PTFs, RSUs, APARs, ++HOLDDATA, vendor advisories, maintenance windows, fallback planning, and deployment governance.
Ability to assess vulnerability findings, CVE applicability, security bulletins, patch exposure, configuration drift, exploitability, compensating controls, remediation complexity, and implementation risk for Db2 for z/OS.
Knowledge of Db2 performance, locking, logging, DDF connectivity, utility execution, package access paths, subsystem contention, and production incident patterns.
Knowledge of z/OS functions relevant to Db2 operations, including APF, link list, LPA, RACF, WLM, SMS-managed datasets, JES, TCP/IP, and certificate management.
Strong written and verbal communication skills.
Any visa is accepted.
