Performance Testing Lead / Architect

Job Title: Performance Testing Lead / Architect Duration: 3 Months C2HLocation: Remote(CST)Exp. Level: 12+ YearsPosition SummaryWe are seeking a Performance Testing Lead / Performance Architect to lead performance strategy, testing, analysis and optimization for complex enterprise applications with heavy API, integration, and transactional workloads. This role focuses on designing realistic performance models, identifying system bottlenecks, and translating performance results into clear business impact and actionable improvements. The ideal candidate goes beyond tool-driven metrics and clearly explains what performance means in real user terms—especially during peak load, high concurrency, and write-intensive workflows. Ideal Candidate ProfileThis person is not just a tester—they are: A performance strategist who models realistic user behavior A technical problem solver who understands APIs, integrations, and system design A clear communicator who bridges engineering detail and business impact They are comfortable challenging assumptions, simplifying complex concepts, and focusing the team on the performance issues that matter most Key Responsibilities Design performance testing strategies that reflect real user behavior, peak load scenarios, and concurrency patterns, not just synthetic TPS/RPS models (e.g., save, verify, post-save flows). Build load models for mixed workloads, including both read and write-heavy transactions execute the same transaction simultaneously. Create targeted tests for worst-case scenarios, including bursts where multiple users end-to-end user journeys. Isolate and test critical high-risk workflows independently (e.g., verify, save), in addition to full. Coordination / leadership of performance team and external team members, e.g. product, development, DBA, middleware, network Assist in the development of estimates for projects Assist with resource assignments and coordinate between teams at multiple locations to ensure on time delivery of projects Work with product and development teams to define and maintain non-functional requirements to work into test plans Deliver effective performance analysis, reporting and presentations to stakeholders ( business, development) Perform the analysis of relationships between the non-functional requirements and key performance metrics Coordinate troubleshooting of infrastructure and application issues Conduct root cause analysis of performance issues and bottlenecks Defect tracking and reporting Work closely with application development and other technical teams to ensure that defects are dealt with in a timely and professional manner Develop and maintain statistical models of key performance metrics Construct and maintain analytical models of applications/systems Mitigate risk by following established procedures and monitoring controls, spotting key errors and demonstrating strong ethical behavior. Required Experience Experience with AI Modelled Agents services for Performance Testing and Analysis activities will be a plus. Expertise in performance analysis of distributed platforms including Linux, Windows, Azure DevOps, Azure Insights, Containers and VMware. Expert in Monitoring / Observability using APM tools like Azure Insights, Dynatrace, AppDynamics, Splunk, DataDog, ELk Kibana, SPLOC, Open Telemetry, Grafana, Prometheus. Substantial knowledge of the functionality and performance aspects of the above computing platforms. Experience in advanced statistical and analytical modeling. Excellent analytical skills including: Data exploration, analysis and presentation utilizing descriptive statistics and graphical techniques Time series analysis and forecasting Key Performance and Volume metrics relationship modeling Understanding of queuing networks modeling and simulation modeling concepts and experience with one of the industry standard analytic modeling tools – TeamQuest, Metron-Athenee, HyPerformix, and BMC Expertise in load testing tools, such as JMeter, LoadRunner etc. Experience in scripting (Perl, Unix shell, Python, Terraform, Chef, Jenkins) Experience using JMS/IBM-MQ messaging system Understanding of RESTful web service, JSON, and XML Experience in RDBMS, DBMS, SQL and NOSQL. Experience working with Azure services (Azure DevOps, Azure Apps, Azure Insights, Virtual Machine, Service Bus, Kubenetes Services etc.). Experience with CI/CD pipeline implementations, including testing, using Jenkins or similar tool. Experience working with Agile teams (preferably scrum).
