Senior Performance Test Engineer

About the Role:

Were looking for a seasoned Performance Test Engineer with 5 years of hands-on experience in performance reliability and resilience engineering for modern cloud-native systems. Youll design and execute endtoend performance testing strategies across Load Stress Spike Endurance Capacity Failover DR Chaos Engineering Fault Injection and Game Day exercises. Youll be deeply technical and comfortable with tools like Apache JMeter Locust AWS Distributed Load Testing (DLT) and AWS Fault Injection Simulator (FIS).

Key Responsibilities Performance & Scalability

• Define and execute performance test strategies covering Load Stress Spike Endurance and Capacity testing.
• Build maintain and optimize test scripts using JMeter and Locust; parameterize correlate and modularize for reusability.

Reliability Resilience & Recovery

• Design and run Failover Disaster Recovery (DR) and Resilience tests to validate RTO/RPO multiAZ/region failover and recovery runbooks.
• Use AWS FIS to inject faults (network latency/packet loss CPU/memory stress AZ disruptions instance terminations) and validate blast radius containment.
• Partner with SRE/Platform teams to define chaos hypotheses measure steady state and implement autoremediation and graceful degradation patterns.

Cloud & Observability

• Use AWS DLT to orchestrate scalable distributed load tests; automate workloads via CloudWatch Events Step Functions or pipelines.
• Instrument and analyze performance using Amazon CloudWatch XRay and APM tools (Dynatrace/AppDynamics) plus Prometheus/Grafana.

Engineering & Automation

• Integrate performance tests into CI/CD (GitHub Actions/Azure DevOps/Jenkins/GitLab) with autogating based on thresholds.
• Build utilities/frameworks for data generation environment setup and report automation (Python/Java).
• Analyze results (percentiles tail latency saturation) identify bottlenecks (DB cache network I/O) and drive fixes with DevOps/Engineering.

Game Days & Readiness

• Plan and facilitate Game Day exercises simulating peak traffic dependency failures regional outages and DR drills.
• Document test plans hypotheses playbooks and postincident reviews with measurable improvements.

Nice to Have

• AWS Certification (Solutions Architect/Developer/SysOps/SRE) plus.
• Experience with Kubernetes/EKS service meshes (Istio) HPA/autoscaling and pod/resource tuning.
• Knowledge of CDNs (CloudFront) Edge compute/ and WAF impacts on performance.
• Familiarity with security/perf tradeoffs TLS tuning connection pooling and circuit breakers.

Qualifications :

• B.E./
• 5 to 7 years of experience in performance engineering for web APIs and distributed systems.
• Strong hands-on expertise with Apache JMeter and Locust (test design correlation parametrization CI integration).
• Practical experience with AWS Distributed Load Testing (DLT) and AWS Fault Injection Simulator (FIS).
• Deep understanding of HTTP/HTTPS WebSockets REST gRPC and messaging systems (Kafka/SQS).
• Proficiency in Python and/or Java for scripting and custom extensions.
• Solid grounding in scalability patterns caching (Redis/Memcached) databases (RDS/Aurora/DynamoDB) and CDN behavior.
• Hands-on experience with observability tools: metrics traces logs dashboards alerting (CloudWatch X-Ray Prometheus/Grafana Datadog/New Relic).
• Experience executing Load Stress Spike Endurance Capacity Failover DR and Chaos/Fault Injection tests and interpreting results.
• Ability to define SLIs/SLOs capacity models and performance budgets; strong data analysis and communication skills.
