• Experience troubleshooting SQL Agent jobs, batch processing, ETL pipelines, and complex process dependencies.

• Ability to analyze unfamiliar legacy code and quickly understand complex business processing logic.

• Strong production troubleshooting and root-cause-analysis skills.

• Experience supporting high-volume, mission-critical production systems where processing accuracy and recoverability are essential.

Preferred Skills

• PowerShell and automation experience.

• SQL Server Profiler, Extended Events, Query Store, and other SQL Server diagnostic tools.

• Experience with very large databases and high-volume batch processing.

• Performance tuning of ETL and data-intensive applications.
