About the role

  • Contribute to driving the overall QA strategy for Mirantis Secure Registry, Kubernetes and cloud-native environments.
  • Evaluate and champion best-in-class testing practices and frameworks for distributed systems.
  • Lead risk analysis and test planning for large-scale, multi-cloud registry, infrastructure and container orchestration.
  • Architect test frameworks and infrastructure for validating microservices and infrastructure components in multi-cluster and hybrid-cloud environments.
  • Oversee the design of complex test scenarios simulating production-like workloads, resource scaling, failure injection, and recovery across distributed clusters.
  • Spearhead the development of scalable and maintainable test automation integrated with CI/CD (Jenkins, GitHub Actions, etc.).
  • Leverage Kubernetes APIs, Helm, and service mesh tools to build comprehensive automation coverage.
  • Promote test infrastructure-as-code and drive IaC forward on the team.
  • Mentor QA engineers and developers in advanced testing techniques.
  • Collaborate with devops engineers to refine monitoring, alerting, and debugging strategies for testing automation being run in CI/CD.
  • Establish quality gates, release readiness metrics, and data driven feedback loops to ensure released software is production quality.
  • Advocate for a culture of quality across teams and influence architecture decisions with testing in mind.

Requirements

  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
  • 10+ years in software testing or quality engineering roles, with 4+ years focused on Kubernetes, cloud-native applications, and distributed systems.

  • Deep understanding of Kubernetes internals, cluster lifecycle management, Helm, service meshes (e.g., Istio or Linkerd), and network policies.
  • Strong scripting and automation capabilities (Python, Pytest, Bash, etc.).
  • Familiarity with observability stacks (Prometheus, Grafana, Jaeger), Kubernetes security (RBAC, secrets management), and performance benchmarking tools (e.g., K6).
  • Solid grounding in cloud architecture (AWS, Azure, GCP), infrastructure provisioning, and containerized CI/CD.
  • Moderate to advanced linux knowledge and proficiency is required: Bash scripting and debugging, systemd/logs, networking/firewalling/routing, certificate/PKI management, containers (Docker/containerd), and Kubernetes tooling (kubectl/Helm with OCI registries, GitOps/Flux) to install, test, and troubleshoot multi-cluster environments.
  • Exceptional problem-solving and architectural thinking.
  • Experience influencing cross-functional teams and senior leadership.
  • Excellent verbal and written communication skills for technical and executive-level audiences.
  • Mentorship and coaching of 1 or more junior members on the team especially around testing fundamentals, troubleshooting and automation.
  • Contributions to open-source Kubernetes or QA tooling projects (preferred).
