Mirantis is seeking a Senior QA Engineer to drive quality strategy and leadership for Kubernetes and cloud-native infrastructure. This role combines strategic QA leadership with hands-on technical architecture, focusing on testing distributed systems at scale.
You will contribute to the overall QA strategy for Kubernetes and cloud-native environments, aligning quality goals with business objectives and release deadlines. You'll evaluate and champion best-in-class testing practices and frameworks for distributed systems, and lead risk analysis and test planning for large-scale, multi-cloud infrastructure and container orchestration.
On the technical side, you'll architect test frameworks and infrastructure for validating microservices and infrastructure components in multi-cluster and hybrid-cloud environments. You'll oversee the design of complex test scenarios simulating production-like workloads, resource scaling, failure injection, and recovery across distributed clusters.
You'll spearhead development of scalable and maintainable test automation integrated with CI/CD (Jenkins, GitHub Actions, etc.), leveraging Kubernetes APIs, Helm, and service mesh tools to build comprehensive automation coverage including system health, failover behavior, and network resilience. You'll promote test infrastructure-as-code and drive it forward on the team, ensuring infrastructure code is repeatable, extensible, and reliable.
Mentorship is a key part of this role. You'll mentor QA engineers and developers in advanced testing techniques such as risk-based testing, chaos engineering, performance and load testing. You'll serve as the QA authority in design reviews, production readiness assessments, and incident retrospectives, and collaborate with DevOps engineers to refine monitoring, alerting, and debugging strategies.
You'll establish quality gates, release readiness metrics, and data-driven feedback loops to ensure released software is production quality. You'll drive initiatives to integrate performance, security, and chaos testing into the development lifecycle and advocate for a culture of quality across teams, influencing architecture decisions with testing in mind.
Mirantis is a Silicon Valley leader in cloud infrastructure, working with Fortune 500 and Global 2000 customers on next-generation cloud technologies. The company is committed to open-source innovation and Kubernetes-native AI infrastructure.

- Proven leadership experience in building and scaling test strategies in enterprise-grade environments
- Deep understanding of Kubernetes internals, cluster lifecycle management, Helm, service meshes (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 (K6)
- Solid grounding in cloud architecture (AWS, Azure, GCP), infrastructure provisioning, and containerized CI/CD
- Moderate to advanced Linux knowledge: 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)

- Experience influencing cross-functional teams and senior leadership
- Excellent verbal and written communication skills for technical and executive-level audiences
- Mentorship and coaching experience with 1 or more junior team members
PREFERRED:
- Contributions to open-source Kubernetes or QA tooling projects
- Experience implementing chaos engineering in Kubernetes environments
