Résumé du poste

EPAM Systems Inc. is seeking a Senior Performance Engineer to define, implement, and execute a comprehensive performance engineering strategy across applications and services. You will validate NFRs, analyze bottlenecks, and drive automated performance testing within cross-functional teams.

You will design load, stress, and capacity tests for web apps, APIs, and backend services, and integrate tests into CI/CD pipelines. Strong tooling skills and AWS scalability awareness are required.

Qualifications

• 3+ years of performance testing/engineering on production web applications and distributed systems.
• Experience with k6, JMeter, Gatling.
• Familiarity with Locust or similar load testing tools.
• Strong understanding of load, stress, and spike testing.
• English proficiency at an Upper-Intermediate level (B2) or higher.

Responsabilités

• Define the overall performance testing and performance engineering strategy based on application architecture, business usage patterns, and NFRs.
• Translate NFRs into measurable performance acceptance criteria, test scenarios, workload models, and success thresholds.
• Design and execute load, stress, spike, endurance/soak, scalability, and capacity tests across web applications, APIs, and backend services.
• Develop and maintain automated performance test scripts and reusable performance testing frameworks.
• Test the performance of HTTP/REST and gRPC-based APIs and services.
• Establish workload models based on expected user volumes, concurrency, and production-like behavior.
• Analyze performance across the full application stack including frontend, APIs, databases, and infrastructure.
• Identify bottlenecks and perform root-cause analysis using observability data.
• Validate application behavior under normal, peak, and sustained workloads.
• Evaluate KPIs such as response time, latency, throughput, error rate, concurrency, CPU, memory, network utilization, and DB performance.
• Integrate performance tests into CI/CD pipelines to support continuous validation and detect regressions.
• Establish baselines and track performance trends across releases.
• Partner with engineers to optimize performance and scalability.
• Produce clear performance test reports and communicate release criteria compliance.
