About This Opportunity

You will be a core QA engineer responsible for the end-to-end quality and reliability of h2o.ai's product portfolio.

This position is based in Bangalore, India.

What You Will Do

• Design, build, and maintain Python-first automation frameworks (pytest + Playwright + async) for UI, API, and end-to-end workflows of h2o.ai's product portfolio.
• Perform deep exploratory and manual testing of the h2o.ai's product portfolio web UI (chat interfaces, document upload/processing, agent builder, maker suite, evaluation hub, enterprise admin console).
• Use h2o.ai's product portfolio itself (and other GenAI tools) in creative ways to:
  • Generate realistic test documents, datasets, and edge-case prompts.
  • Auto-generate or refine test cases via prompt engineering.
  • Rapidly summarize and debug massive, complex log files (e.g., Kubernetes pods, etc.).
  • Explain cryptic LLM traceback chains or hallucination root causes in seconds instead of hours.
• Root-cause of difficult, intermittent failures in distributed RAG/LLM systems by combining traditional log analysis with GenAI-assisted debugging.
• Create and execute chaos experiments targeting LLM routing, vector database latency, GPU OOM, retrieval failures, and token-limit edge cases.
• Build and manage ephemeral h2o.ai's product portfolio clusters on Kubernetes for testing (Helm, custom operators).
• Own UI regression suites (Playwright) and accessibility testing.
• Write reproducible, high-quality bug reports that developers love and regularly verify fixes across the full stack.
• Collaborate closely with the h2o.ai's product portfolio feature teams in an Agile environment and influence testability from the design phase.

What We Are Looking For

• 2-4 years of QA experience with a strong mix of automation and hands-on manual/exploratory testing.
• Decent Python skills and experience building maintainable test frameworks from scratch.
• Real-world experience testing modern React/TypeScript web applications and writing bulletproof Playwright or Selenium tests.
• Hands-on Kubernetes experience in a testing or test-environment context (kubectl, Helm, writing manifests, debugging pods).
• Proven ability to use generative AI tools daily to accelerate debugging, test-data creation, and log analysis (you’ve already used h2o.ai's product portfolio, ChatGPT, Claude, or similar in your current QA workflow).
• Comfort reading and triaging complex logs from LLM frameworks, vector DBs, and tracing systems.
• Solid grasp of CI/CD (GitHub Actions preferred) and infrastructure-as-code concepts.

How to Stand Out From the Crowd

• Prior experience testing RAG systems, agentic workflows, or enterprise chat/assistant platforms.
• Experience with visual diffing of generated outputs (documents, charts, markdown).
• Chaos engineering on Kubernetes (Chaos Mesh, Litmus) or GPU workloads.
• Familiarity with Chaos engineering principles.
• Basic understanding of containerization (Docker/Kubernetes concepts like pods and kubectl) in a testing context.
