Senior IBM Db2 Database Engineer

• Evaluate the existing Db2 platform, operating model, and supporting architecture to uncover performance gaps, capacity concerns, security risks, and reliability issues.
• Analyze workload behavior across transactional processes and reporting activity, using execution plans, indexing strategy, locking patterns, memory settings, logging, and storage usage to recommend measurable improvements.
• Review custom SQL and related application workflows, then refine inefficient queries or propose alternative functional approaches when database changes alone are not the best solution.
• Resolve production-facing database and platform problems, including slowdowns, failed scheduled processing, storage limitations, replication concerns, backup or recovery issues, and interruptions to availability.
• Improve the Windows-based environment currently supporting Db2 by assessing server configuration, memory utilization, disk and file system performance, network settings, service permissions, and security controls.
• Build and enhance automation for recurring operational checks, configuration validation, backup confirmation, and ongoing monitoring using PowerShell or similar scripting tools.
• Support the migration of a large production Db2 database from Windows to Linux by defining readiness criteria, dependency reviews, data movement strategy, testing plans, cutover activities, rollback steps, and post-go-live stabilization.
• Configure and tune Linux infrastructure for Db2, including storage mounts, permissions, resource thresholds, networking, service management, and monitoring integration.

• Work closely with vendor support and engineering teams to investigate open cases, accelerate issue resolution, and validate platform changes through benchmarking and documented runbooks. Requirements - Strong hands-on experience architecting, administering, and optimizing IBM Db2 environments that support high-volume business applications.
• Proven ability to diagnose database performance issues using SQL analysis, execution plans, indexing methods, locking behavior, and resource utilization metrics.
• Experience supporting production platforms across Windows and Linux server environments, including storage, networking, security, and system configuration.
• Demonstrated background in planning and executing database migration initiatives with attention to testing, rollback preparation, continuity, and post-migration validation.
• Proficiency in scripting or automation tools such as PowerShell to streamline health checks, validation routines, and operational support tasks.
• Working knowledge of backup, recovery, monitoring, high availability, and disaster recovery practices for enterprise database systems.
• Ability to produce clear technical documentation, risk assessments, and procedural guidance for infrastructure, database, and support teams.
