Automate performance test execution within CI/CD pipelines to support repeatable validation, early performance feedback, and release readiness. Results Analysis and Reporting (25%) Analyze performance and resiliency test results across application, database, middleware, network, cloud, and infrastructure layers. Monitor and evaluate key metrics such as response time, throughput, transaction volume, CPU, memory, I/O, queue depth, latency, error rates, auto-scaling behavior, failover behavior, recovery time, system recovery, and service degradation patterns. Identify bottlenecks, resiliency gaps, and performance risks, compile findings, and communicate clear recommendations to technology, product, and leadership stakeholders. Cloud and Data Platform Performance Engineering (25%) Support performance engineering for cloud modernization, data platform migrations, and high-volume processing solutions. Validate performance, scalability, and resiliency of AWS services, cloud-native architectures, containerized workloads, data ingestion jobs, ETL and ELT pipelines, PostgreSQL and other database platforms, data warehouse workloads, and data lake integrations. Partner with architecture and engineering teams to recommend tuning opportunities, capacity improvements, resiliency improvements, automation enhancements, and long-term performance solutions. Technical Leadership and Mentoring (25%) Provide technical leadership for performance testing engagements supporting critical, high-visibility applications and platforms. Lead defect triage and root-cause analysis for performance issues, and support production incident analysis where performance is a contributing factor. Help establish performance baselines, dashboards, and reporting standards. Mentor team members on performance testing best practices, NeoLoad scripting and execution, cloud observability, test automation integration, CI/CD performance test automation, and continuous performance testing within delivery pipelines. Education Bachelor's degree in Information Technology or Computer Science. Requirements Required Skills and Qualifications Five years of experience in performance testing, resiliency testing, performance engineering, or quality engineering for enterprise applications, including hands-on experience with workload modeling, performance test design, resiliency test scenarios, failover validation, test execution, monitoring, bottleneck analysis, recovery analysis, and results reporting. Experience with Tricentis NeoLoad and LoadRunner. Strong cloud and CI/CD performance test automation experience, including cloud platforms such as AWS, database performance validation, and large-scale data warehouse or data lake environments. Ability to communicate technical requirements to all levels of expertise. Knowledge and understanding of the performance testing lifecycle, SDLC, Agile delivery, and non-functional requirements validation. Proficiency integrating performance testing into complex enterprise systems, cloud-native applications, APIs, microservices, data warehouse platforms, and data lake pipelines. Knowledge of scripting, programming, or query languages used in performance testing and analysis, such as JavaScript, Java, Groovy, Python, SQL, or shell scripting. Excellent written and verbal communication skills. Knowledge of cloud technologies with emphasis on AWS-native applications, cloud scalability, auto-scaling behavior, monitoring, observability, resiliency testing, failover validation, recovery analysis, and capacity validation.
