4. Infrastructure & CI/CD: GitHub Actions, Docker, Kubernetes, Helm
5. Observability: Prometheus, Grafana (or equivalents)
6. Architectures: microservices, async messaging (Kafka, RabbitMQ, Redis, gRPC, WebSockets)
7. Performance/Security: JMeter, k6, OWASP ZAP, Burp Suite (any is acceptable)

  Support internal QA teams with best practices, help eliminate flaky tests, improve coverage strategies, and strengthen CI/CD integration.
  
  

Required Skills

1. 7+ years of experience in automation engineering.
2. Strong Python automation background (Pytest + Playwright/Selenium).
3. Working Java knowledge for building frameworks, maintaining existing codebases of tests and coverage of enterprise systems.
4. Experience with large distributed systems (microservices, RESTfull web services and async communications).
