Performance Engineer & Optimization Specialist

We are seeking an experienced Performance Engineer and Optimization Specialist with strong expertise in Oracle LoadRunner , .NET applications , and SQL Server performance tuning . The ideal candidate will be responsible for end-to-end performance testing, analysis, and optimization of enterprise-grade .NET and database-intensive applications.

Job Title: Performance Engineer & Optimization Specialist
Role Focus: LoadRunner Performance Engineer .NET & SQL Server Optimization

Location: Remote (Occasional co-location required)

Key Responsibilities

• Collaborate with architects, developers, DBAs, and business analysts to define performance testing objectives.
• Establish key performance metrics and SLAs, including response times, throughput, database latency, and resource utilization.
• Define end-to-end performance test scenarios under varying load conditions.

• Develop and parameterize LoadRunner scripts simulating real-world user activity across .NET web applications, APIs, and database-heavy workflows.
• Design SQL Serverspecific performance scenarios, including complex queries, batch processing, and high-volume data ingestion.
• Integrate automated performance tests into CI/CD pipelines and schedule recurring test executions.

• Coordinate with infrastructure teams to configure application and database test environments (IIS, .NET versions, SQL Server instances).
• Implement monitoring solutions, including Windows PerfMon, LoadRunner monitors, SQL Server Profiler, Extended Events, and .NET profilers.

• Execute load, stress, and soak tests using LoadRunner Controller.
• Monitor application and database performance simultaneously to identify bottlenecks.
• Track ASP.NET performance indicators ( threading, memory) and SQL Server health metrics (locks, deadlocks, slow queries, indexing).

• Analyze performance test results across application, database, and infrastructure layers.
• Perform root cause analysis using LoadRunner Analysis, .NET profiling tools (Visual Studio Profiler, dotTrace), and SQL Server tools (Query Store, execution plans).
• Recommend and implement performance improvements:
• .NET: Code refactoring, caching strategies, async/threading optimizations, configuration tuning.
• SQL Server: Query and stored procedure tuning, index optimization, execution plan analysis, partitioning, and schema enhancements.

• Prepare comprehensive performance reports, dashboards, and executive summaries.
• Clearly communicate findings, risks, and recommendations to both technical and business stakeholders.

• Stay current with advancements in LoadRunner, .NET, SQL Server, and Azure monitoring tools.
• Maintain and enhance performance test suites as applications evolve.
• Promote performance engineering best practices across teams.
