SQL Database Administrator

Role Summary: We are seeking a Senior SQL Database Engineer to design, optimize, and support high-volume, enterprise SQL Server platforms that power transaction processing, reporting, compliance, and data-feed workloads. This role combines deep T-SQL engineering with production troubleshooting, performance analysis, database reliability, and modernization of database-heavy processing.

Key Responsibilities: Design, develop, review, and optimize complex T-SQL, stored procedures, functions, views, tables, indexes, and data-access patterns. Analyze execution plans, Query Store data, waits, blocking, memory grants, parallelism, CPU, I/O, tempdb usage, and transaction-log behavior to isolate and resolve performance issues. Refactor row-by-row and scalar-function-heavy processing into efficient set-based designs, including appropriate use of inline table-valued functions, temporary staging, indexing, and early filtering. Tune long-running batch, snapshot, compliance, reporting, and data-export workloads while preserving data integrity and output equivalence. Design and validate database structures, keys, identity strategies, data models, and replication patterns for large, tightly coupled transactional workloads. Support SQL Server upgrades and configuration changes through representative performance testing, execution-plan comparison, regression validation, and documented rollback or fix-forward plans. Engineer and support high availability, disaster recovery, transactional replication, monitoring, maintenance, archival, purge, and capacity-management practices. Troubleshoot production incidents with application, infrastructure, SRE, QA, and vendor teams; preserve evidence and translate findings into durable corrective actions. Contribute to cloud and platform modernization involving Azure SQL Managed Instance, Azure SQL, data pipelines, and workload offload from monolithic SQL platforms. Provide technical leadership through design reviews, code reviews, standards, documentation, mentoring, and knowledge transfer.
