We’re seeking a hands-on Performance Test Engineer / Performance Tester with strong Python and automation expertise to design, build, and execute the performance testing strategy for a high-scale, ad-serving platform built on Akka-based Java microservices. Ideally required to build automated load frameworks using Locust (Python). It’s important to the end client that suitable candidates have solid experience in the streaming domain and with issues related to handling millions of concurrent users, and that they are strongly focused on performance testing.
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 across cloud infrastructure and code. This is a technical, high-impact role ideal for someone passionate about distributed systems performance, automation, and data-driven tuning.
Profile:
- 3-5+ years of performance engineering for large-scale, low-latency, distributed systems.
- Proven success meeting p95/p99 latency SLAs under high concurrency (millions of RPS).
- Strong Python and automation expertise – able to design reusable, scalable test frameworks.
- Experience with distributed load testing and synthetic traffic modeling in the cloud.
- Analytical, structured, and effective communicator with strong documentation and collaboration skills.
- Solid experience in the streaming video / advertising domain and with issues related to handling millions of concurrent users.
- Someone passionate about distributed systems performance, automation, and data-driven tuning.
- Based in EU or UK with English (C1 or higher) and right to work in the region.
Nice to have: Java, Bash scripting, Terraform.
Key Responsibilities:
- Define and execute comprehensive performance test plans (load, stress, spike, soak, scalability, failover).
- Model real-world streaming traffic patterns (burstiness, fan-out, cache behaviour, 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 to analyze system bottlenecks.
- Develop SLA/SLO dashboards and integrate performance gates into CI/CD pipelines.
- Collaborate with DevOps 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: Akka-based asynchronous Java microservices.
