    Requirements

    * 3-6+ years of experience in QA, SDET, or evaluation-focused ML/AI testing, preferably with nondeterministic or probabilistic systems.

    * Strong Python scripting skills for test automation, scenario evaluation, and defect detection.

    * Experience with ML evaluation tools, LLM/RAG testing, or model benchmarking suites.

    * Familiarity with vector databases, retrieval systems, multi-agent workflows, and AI pipelines.

    * Understanding of CI/CD pipelines, DevOps tooling, and observability platforms.

    Roles and Responsibilities

    * Define and own the end-to-end QA strategy across UI, backend, data, and AI components.

    * Design and implement test plans covering functional, non-functional, and behavioral requirements.

    * Build automated and manual evaluation suites for LLMs, retrieval systems, and agent workflows.

    * Conduct scenario-based tests, regression tests, and red-team exercises to uncover edge cases and risks.

    * Validate data quality, embedding correctness, retrieval accuracy, and monitor for model drift or hallucinations.

    * Define metrics, logs, dashboards, and alerts to monitor AI behavior, latency, cost, and errors.

    * Detect and escalate reliability, bias, and performance issues early in the delivery cycle.

    * Manage defect triage workflows, categorize failures across UI, API, data, and model layers, and ensure clear reproduction documentation.

    * Integrate automated tests into CI/CD pipelines to catch regressions early.

    * Support pods in delivering safe, reliable, and stable AI behavior for all experimental and production features.
