• Design and optimize partitioning, HA/DR, Always On Availability Groups, and SQL Server Replication.
• Support large-scale, high-concurrency OLTP environments and multi-TB databases.
• Review application/ORM-generated SQL and provide performance recommendations to development teams.
• Build automation using T-SQL and PowerShell/dbatools.
• Lead production troubleshooting, RCA, performance improvements, and capacity planning.
• Mentor DBAs and developers and communicate technical findings to leadership.

Required Qualifications

• 10+ years of hands-on SQL Server DBA/Database Engineering experience.
• 5+ years in a senior performance-focused role.
• Expert knowledge of SQL Server 2016 2022 internals.

• Strong experience with Query Store, Extended Events, DMVs, and wait-statistics analysis.
• Proven experience resolving database performance bottlenecks, contention, blocking, and deadlocks.
• Hands-on experience with partitioning, Always On AGs, and replication.
• Experience with high-volume OLTP / large-scale databases.
• Financial services, banking, or payments experience preferred.
• Strong communication skills and ability to work directly with engineering and business stakeholders.

Preferred

• Azure SQL / SQL Server on Azure or AWS
• Cloud performance and cost optimization
• Database DevOps / CI/CD
• PostgreSQL, Cosmos DB, or Snowflake
• PowerShell/dbatools
• PCI-DSS, SOX, GLBA, or similar regulated environments
