This is a hands-on role that designs and executes performance testing strategies, integrates them into CI/CD practices, and collaborates closely with engineering teams to optimize application performance across the .NET technology stack

Primary Responsibilities:

Performance Testing Execution:

• Design, develop, and execute performance, load, and stress tests using
  Design, develop, and execute performance, load, and stress tests using JMeter and industry-standard approaches.
• Analyze test results to identify bottlenecks (CPU, memory, I/O, database, network) and recommend code/configuration optimizations.
• Integrate performance testing into CI/CD pipelines using GitLab; author and maintain pipeline jobs, artifacts, and thresholds.

System Reliability & Scalability:

• Validate application performance under varying loads and peak events for web and client-server applications.
• Collaborate with developers and architects to embed performance considerations (capacity, caching, concurrency) in design and development.
• Partner with database engineers to tune queries, indexes, and connection strategies for .NET/SQL workloads.

Technical Architecture & Documentation:

• Create and maintain performance test plans, scenarios, scripts, and data models; define entry/exit criteria and SLAs.
• Document performance benchmarks and trends; provide actionable insights for capacity planning and release readiness.
• Author clear defect reports and engineering recommendations with reproducible steps and supporting metrics.

Environment & Tooling:

• Leverage Azure (strong plus) for test environments, scaling, and monitoring; collaborate on infrastructure-as-code where applicable.
• Utilize monitoring and log analysis tools (e.g., Splunk, ELK) to correlate performance metrics with system behavior and trace root causes.
• Work closely with DevOps to maintain test harnesses, datasets, synthetic users, and environment parity across stages.

Collaboration & Continuous Improvement:

• Embed performance testing into Agile/SAFe workflows (Definition of Ready/Done); participate in sprint ceremonies and release planning.
• Recommend tools, frameworks, and standards for performance engineering; coach developers and QA on profiling and tuning best practices.

Compliance:

Education and Experience (Required):

Degree: Bachelors’ degree and 5+ years' experience in performance testing/QA, or equivalent combination of education and experience

Technical Expertise:

• Strong hands-on experience with Apache JMeter (test plan design, parameterization, correlation, distributed testing, and reporting).
• CI/CD: GitLab pipelines (YAML), test gating with pass/fail thresholds, artifact management, and integration with .NET builds.
• .NET stack familiarity (C#, ASP.NET, Entity Framework/SQL Server); ability to collaborate on code-level and config tuning.
• Experience testing both web applications and client-server applications across custom and COTS solutions.
• Exposure to Microsoft Azure for environment provisioning, monitoring, and scaling (strong plus).

Financial Technology Systems: Some experience with client management, core banking, payments, financial reporting, loan management, or fraud/AML management solutions.

Vendor Management: Some experience with COTS business application vendors, IT vendors, and contract management.

Soft Skills: Technical leadership, people management, problem-solving, communication, time-management, cross-functional team coordination, and technical mentorship
