We are seeking a
Senior QA Engineer
to ensure the
quality, reliability, and performance
of our
Edge Kubernetes Platform
, supporting both connected and air-gapped environments. This is a hands-on role where you will design and implement
automated testing frameworks
, validate complex distributed edge systems, and partner with engineering teams to deliver secure, scalable, and resilient platforms.

As a Senior QA Engineer, you will own
test strategy, automation frameworks, and quality processes
for platform components, with a focus on Kubernetes, Rancher Gov stack, and edge deployments.

Key Responsibilities

  • End-to-End Test Strategy: Define and execute test plans covering functional, integration, performance, upgrade, and security testing for Kubernetes-based edge platforms.
  • Automation Leadership: Build and extend automated test frameworks for UI, API, and platform-level validation (Selenium, Cypress, Playwright, PyTest, etc.).
  • CI/CD Integration: Integrate automated test suites into CI/CD pipelines, ensuring rapid, reliable quality feedback.
  • Platform & Edge Validation: Test Kubernetes clusters (upstream, RKE2) in air-gapped and edge environments, validating multi-cluster operations and lifecycle management.
  • Upgrade & Resilience Testing: Design and execute tests for cluster upgrades, workload orchestration, and fault-tolerance scenarios.
  • Performance & Scalability Testing: Conduct benchmarking, load, and stress tests to validate system reliability in resource-constrained edge environments.
  • Security & Networking Validation: Partner with security and platform engineers to verify network segmentation, access controls, and zero-trust enforcement.
  • Defect Management: Identify, document, and drive defect resolution across cross-functional teams.
  • Process Improvement: Mentor QA engineers, contribute to quality best practices, and continuously evolve test strategies for distributed edge systems.

Qualifications

  • 7+ years of experience in software QA, including 3+ years in test automation for distributed or platform-level systems.
  • Hands-on expertise with automation frameworks (Selenium, Cypress, Playwright, PyTest, or similar).
  • Proven experience testing Kubernetes (upstream, RKE2), Rancher, and containerized microservices.
  • Familiarity with air-gapped deployments, edge environments, and distributed system testing.
  • Strong knowledge of CI/CD pipelines, Docker, and Linux systems.
  • Experience with API testing tools (Postman, REST Assured) and databases (SQL/NoSQL).
  • Practical knowledge of performance/load testing tools (JMeter, Locust, Gatling).
  • Excellent debugging, analytical, and communication skills, with experience collaborating in agile teams.

Nice to Have

  • Experience validating Rancher Gov stack, GitOps (ArgoCD, Fleet), or Helm-based deployments.
  • Exposure to observability stacks (Prometheus, Grafana, Loki, ELK).
  • Familiarity with security testing frameworks (OWASP ZAP, Burp Suite).
  • Contributions to open-source QA frameworks or Kubernetes ecosystem projects.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
