We are looking for a Performance Engineer to contribute to the implementation and execution of the performance engineering approach for our applications and supporting services. In this role, you will validate Non-Functional Requirements (NFRs), including response time, throughput, scalability, stability, and resource utilization.The engineer will work closely with development, DevSecOps, architecture, and product teams to help identify performance risks early, build automated performance testing capabilities, analyze system behavior under realistic workloads, and ensure applications meet agreed performance and scalability targets before production release.ResponsibilitiesContribute to the performance testing and performance engineering strategy based on application architecture, business usage patterns, and NFRsHelp translate business and technical NFRs into measurable performance acceptance criteria, test scenarios, workload models, and success thresholdsExecute load, stress, spike, endurance/soak, scalability, and capacity tests across web applications, APIs, and backend servicesDevelop and maintain automated performance test scripts using existing performance testing frameworksTest the performance of HTTP/REST and gRPC-based APIs and servicesBuild workload models based on expected user volumes, concurrency, transaction patterns, and production-like behaviorAnalyze performance across the application stack, including frontend, APIs, services, databases, caching layers, infrastructure, and third-party dependenciesIdentify performance bottlenecks and participate in root-cause analysis using application, infrastructure, database, and observability dataValidate application behavior under normal, peak, and sustained workloadsMeasure key performance indicators such as response time, latency, throughput,



error rate, concurrency, CPU, memory, network utilization, and database performanceIntegrate performance tests into CI/CD pipelines to support continuous performance validation and detect regressions earlyHelp establish performance baselines and track performance trends across releasesCollaborate with software engineers and DevSecOps teams to validate performance optimizationsProduce clear performance test reports, highlight risks, and communicate whether agreed NFRs and release criteria have been metSupport capacity planning activities for application and AWS infrastructure scalabilityRequirements2+ years of performance testing/performance engineering experience with web applications and distributed systemsHands-on experience with performance testing tools such as k6, JMeter, or GatlingFamiliarity with Locust or similar load testing toolsSolid understanding of load, stress, and spike testingWorking knowledge of endurance/soak, scalability, and capacity testingIntermediate English proficiency (B1+ level)We offerInternational projects with top brandsWork with general teams of highly skilled, diverse peersHealthcare benefitsEmployee financial programsPaid time off and sick leaveUpskilling, reskilling and certification coursesUnlimited access to the LinkedIn Learning library and 22,000+ coursesGlobal career opportunitiesVolunteer and community involvement opportunitiesEPAM Employee GroupsAward-winning culture recognized by Glassdoor, Newsweek and LinkedInEPAM is an Equal Opportunity Employer.
