Principal Eng, Test(Performance Testing)

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.
• Strong programming or scripting skills in Java, Scala, Python, or a comparable language for framework and utility development.
• Deep understanding of HTTP/HTTPS, REST APIs, web applications, microservices, messaging, databases, caching, networking, and distributed-system behavior.
• Experience testing cloud and container platforms, including Azure, Docker, Kubernetes, autoscaling, service discovery, and resource constraints.
• Proficiency with observability and analysis tools such as Grafana, Prometheus, Application Insights, centralized logs, APM tools, and database diagnostics.
• Experience defining service-level indicators, service-level objectives, percentile response-time targets, throughput, error-rate, saturation, and capacity measures.
• Strong CI/CD, Git, test-data, environment, reporting, and automated threshold-management experience.
• Proven technical leadership, stakeholder communication, mentoring, and performance-risk decision-making skills.

Preferred Skills

• Experience with event-driven services, RabbitMQ, Azure Service Bus, MQTT, streaming platforms, Redis, PostgreSQL, or similar technologies.
• Experience with resilience and chaos testing, failover validation, service-mesh telemetry, and production-capacity planning.
• Knowledge of healthcare interoperability connected medical devices, regulated software verification, or audit-ready performance evidence.
• Relevant cloud, performance-testing, architecture, or reliability-engineering certification is advantageous.
• Knowledge of SIP infrastructure and media components such as Kamailio, FreeSWITCH, RTPEngine, SBCs, registrars, RTP, and WebRTC.
• Experience with Azure Key Vault, Azure App Configuration, Azure Cache for Redis, Azure Web PubSub, Terraform, KEDA, and container security tooling.
• Experience with Jira, Jama, validated toolchains, Agile/Scrum delivery, and formal release-readiness reviews.
• Experience in leading team of performance testers for common goals.
