  • Assess and promote modern testing methodologies tailored to cloud-native systems and distributed architectures.
  • Lead risk assessment and test planning for large-scale, multi-cloud deployments involving container orchestration and registry services.
  • Design and implement test frameworks that validate microservices and infrastructure across hybrid and multi-cluster environments.
  • Create realistic test scenarios that mimic production conditions, including workload stress, scaling events, and failure recovery.
  • Build and maintain automated testing systems integrated into CI/CD workflows using tools like Jenkins and GitHub Actions.
  • Use Kubernetes APIs, Helm, and service mesh technologies to automate validation of system health, failover, and network behavior.
  • Advance infrastructure-as-code practices to ensure test environments are consistent, reusable, and reliable.
  • Coach team members in advanced testing disciplines such as risk-based testing, chaos engineering, and performance evaluation.
  • Participate in design reviews and post-incident analysis to improve product quality and prevent future defects.
  • Work closely with DevOps to enhance monitoring, alerting, and diagnostics within automated test pipelines.
  • Define quality checkpoints, release criteria, and feedback mechanisms to support data-driven release decisions.
  • Integrate performance, security, and resilience testing into the development lifecycle.
  • Champion quality-first thinking across engineering teams and contribute to architectural discussions with a testing perspective.
