to design, build, and execute the performance testing strategy for a high-scale, ad-serving platform built on Akka-based Java microservices. Required to build automated load frameworks using Locust (Python). You'll work closely with developers and DevOps engineers to simulate realistic traffic at scale, ensure sub-50ms latency under millions of concurrent users, and drive system optimizations … plans (load, stress, spike, soak, scalability, failover). Model real-world streaming traffic patterns (burstiness, fan-out, cache behavior, cold-start, geo distribution). Build automated load frameworks using Locust (Python) or JMeter, with data parameterization and correlation. Manage distributed load generation (containers, cloud workers) to simulate millions of concurrent users. Integrate performance metrics from CloudWatch, Prometheus, Grafana, and OpenTelemetry … and developers to tune JVM, Akka, thread pools, GC, caching, autoscaling, and database performance. Document test approaches, scenarios, results, and provide clear, actionable tuning recommendations. Tech Stack: Load Tools: Locust (Python), JMeter; k6 or Gatling (nice to have). Languages: Python, Bash, Java (Maven/Gradle, JVM tuning basics). Infrastructure: Docker, Kubernetes, Terraform. Observability: CloudWatch, Prometheus, Grafana, OpenTelemetry. Architecture More ❯
