Job Summary

We are seeking a Principal Performance Test Engineer with 12+ years of experience in owning performance, scalability, reliability, and capacity-validation strategy for cloud-native and distributed products. The engineer will architect reusable automation using JMeter, LoadRunner, and Gatling; integrate tests with CI/CD and observability platforms; analyze system behavior under load; and guide engineering teams toward measurable performance and resilience goals.

What you’ll be doing

• Define performance-engineering strategy for load, stress, endurance, spike, scalability, resilience, capacity, and failover testing.
• Architect reusable frameworks and workload models using JMeter, LoadRunner, Gatling, or an appropriate combination of tools.
• Translate production usage patterns, service-level objectives, transaction volumes, concurrency, and data profiles into realistic test models.
• Develop reusable protocol libraries, correlation and parameterization utilities, data generators, environment controls, result parsers, and reporting dashboards.
• Integrate performance suites into CI/CD pipelines for baseline, component, scheduled, and release-level execution.
• Correlate client-side results with application, infrastructure, container, database, queue, and network telemetry.
• Identify bottlenecks, support root-cause analysis, recommend tuning, and verify corrective actions with development, architecture, DevOps, and database teams.
• Define performance acceptance criteria, baselines, capacity thresholds, trend analysis, and go/no-go recommendations.
• Lead tool evaluations, framework governance, script reviews, mentoring, and performance-engineering standards across teams.

What you’ll bring

• B.E/B. Tech in Computer Science / Electronics & Communication / Electrical or related field
• Extensive hands‑on performance automation experience with JMeter, LoadRunner, and Gatling, including scripting, correlation, parameterization, workload modelling, execution, and analysis.
