Lighthouse Technology Services is partnering with our client to fill their Performance Test Engineer position! This is a 12+ month contract opportunity and will be hybrid in Wilmington, DE. This role will be a W2 employee of Lighthouse Technology Services.

Position Overview

Our client, a leading financial services organization, is undergoing a strategic digital transformation to deliver high-performing, reliable technology solutions. As a Performance Test Engineer, you’ll play a critical role in ensuring the scalability, stability, and responsiveness of enterprise applications - primarily web-based and select client-server systems, including both custom-built and commercial off-the-shelf (COTS) solutions. This is a hands-on role responsible for designing and executing performance testing strategies, integrating them into CI/CD pipelines, and partnering closely with engineering teams to optimize application performance across the .NET technology stack.

What You’ll Be Doing

Performance Testing Execution:

• 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:

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

What You’ll Need to Have

• Strong 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#, .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)
• Familiarity with financial technology systems such as client management, core banking, payments, or loan management
• Experience with vendor and contract management
• Strong technical leadership, communication, and cross-functional collaboration skills
• Bachelor’s degree and 5+ years of performance testing/QA experience, or equivalent combination of education and experience

Preferred Skills & Experience

• DevOps tools: Git, GitLab, Artifactory, NuGet, NPM, NodeJS, Docker, Kubernetes, Azure DevOps, MS Build, SonarQube
• Scripting: YAML, PowerShell, Linux/Bash, Perl
• Jira, Confluence
• Financial industry experience in institutional financial products such as Corporate Trust Accounts, Investment Funds, Bonds, or Structured Finance

Pay Range: $77-$92+/hr
