Database Performance & Benchmark Engineer

Senior Database Performance & Benchmark Engineer, the responsible for designing and executing rigorous testing strategies across a complex hybrid
environment consisting of large-scale on-premises SQL Server instances and public cloud managed database services. You will act as the bridge between infrastructure engineering, database administration, and application development to ensure our systems are resilient, highly scalable, and optimized for peak
production workloads.

Responsibilities

• Hybrid Benchmarking & Load Testing: Design, script, and execute comprehensive load, stress, and
  endurance tests utilizing synthetic tools (e.g., HammerDB, OStress, Apache JMeter) and production
  replay tools (e.g., WorkloadTools, DEA).
• Performance Telemetry & Monitoring: Establish performance baselines and build continuous
  monitoring dashboards utilizing OS-level metrics (PerfMon/Linux Sysstat) and SQL Server Dynamic
  Management Views (DMVs).
• Cloud Migration & Scaling Validation: Benchmark on-premises workloads and simulate equivalent
  performance in public cloud environments (such as AWS RDS/EC2, Azure SQL, or GCP Cloud SQL)
  to accurately size cloud infrastructure and control costs.
• Bottleneck Isolation & Optimization: Analyze execution plans, identify plan regressions, and isolate
  resource contention bottlenecks (CPU, Memory, Disk I/O, TempDB, and network latency).
• Concurrency & Lock Management: Diagnose and resolve complex locking, blocking, and deadlock
  scenarios discovered during high-concurrency simulation cycles.
• Cross-Functional Collaboration: Partner with Performance QA, DevOps, Infrastructure, and
  Application teams to establish quality gates and provide actionable code/indexing optimization
  recommendations.

Qualifications

Must-Have:

• Bachelor’s degree in computer science, information technology, engineering, or a related discipline, or equivalent with 7+ years  of experience in dedicated database administration (DBA), database engineering, or specialized database performance testing experience.
• Hybrid Environment Mastery: Proven track record managing or benchmarking both traditional
  on-premises enterprise hardware and public cloud architectures (AWS, Azure, or GCP).
• Deep SQL Server Internals: Expert-level knowledge of SQL Server query optimization, execution plan
  analysis, Query Store, Extended Events (XEvents), and system DMVs and Extensive experience setting up and operating database benchmarking suites such as HammerDB, SQLQueryStress, OStress, or similar automated simulation frameworks.
