Performance Testing Lead / Architect

About the role

We 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.

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).
• Create load models for mixed workloads, including both read and write-heavy transactions executed 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.
• Cookordination / leadership of performance team and external team members, e.g. product, development, DBA, middleware, network.
• Assist in the development of estimates for 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.
• Maintain analytical models of applications/systems.
• Mitigate risk by following established procedures and monitoring controls, spotting key errors and demonstrating strong ethical behavior.

Requirements

• 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.
• Expertise 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.
