Performance Test Engineer

CTG Performance Test Engineer

CTG is seeking to fill a Performance Test Engineer opening for our client in Wilmington, Delaware.

Location

Wilmington, DE

Duration

12 months

Role Overview

The Performance Test Engineer ensures the scalability, stability, and responsiveness of application services—primarily web-based and select client-server applications (a mix of custom-developed and commercial off-the-shelf (COTS) solutions). 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

• 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 Git Lab; 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 Dev Ops 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

• Ensure adherence to internal controls, audit requirements, and regulatory standards when testing, storing, and reporting performance data.

Education and Experience (Required)

Degree: Bachelor’s 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:
  Git Lab 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.

Education and Experience Preferred Dev Ops

• CI/CD pipelines, YAML, Dev Ops toolsets (Git, Git Lab, Artifactory, NuGet, NPM, NodeJS, Docker, Kubernetes, Azure Dev Ops, MS Build, Sonar Qube), scripting (YAML, Power Shell, Linux/Bash, Perl).

Tools

Jira, Confluence.
