QA Engineer for AI Products/Solutions

Hi, Please review the below JD: QA Engineer for AI Products/Solutions Location - Bellevue WA Job Description • Design and execute test plans for AI/ML-driven features, including model outputs, prompts, and integrated application behavior • Build and maintain automated test suites covering functional, regression, integration, and API testing • Evaluate model outputs for accuracy, consistency, bias, hallucination, and edge-case failures • Develop evaluation frameworks and golden datasets/test cases to benchmark model performance over time • Test prompt engineering changes, model version upgrades, and fine-tuning outputs for regressions • Perform adversarial and red-team style testing to surface safety, security, and robustness issues • Validate data pipelines feeding into AI models (data quality, schema, drift detection) • Collaborate with data scientists/ML engineers to define acceptance criteria and quality metrics for models • Test latency, scalability, and reliability of AI services under load • Contribute to CI/CD pipelines, integrating automated and model-evaluation tests • Hands-on experience testing LLM-based products (chatbots, copilots, RAG systems, AI agents) — designing test cases for non-deterministic, generative outputs • Practical experience with AI/LLM evaluation frameworks (e.g., Ragas, DeepEval, LangSmith, Promptfoo, OpenAI Evals, TruLens) — building eval suites, scoring rubrics, and golden datasets • Working knowledge of eval metrics for generative AI: hallucination rate, faithfulness/groundedness, relevance, answer correctness, toxicity/bias scoring, BLEU/ROUGE/semantic similarity where applicable • Experience with prompt regression testing — validating prompt changes and model/version upgrades against baseline eval sets • Strong proficiency in Python for writing eval scripts, test harnesses, and data validation logic • Familiarity with SQL and data validation techniques The environment is primarily Microsoft Azure-based, with Snowflake also playing a key role. Their GenAI initiatives largely leverage OpenAI and Claude models. Sophus IT Solutions
