Our client is establishing a brand-new capability within their AI Platforms Team and are looking for a bilingual AI QA / Evaluation Engineer to build evaluation foundation from scratch.

- Test System Correctness: Validate that agentic systems demonstrate sound reasoning, strict retrieval accuracy, correct tool execution, and reliable fallback handling.
- Mitigate Risk & Hallucinations: Define methodologies to detect production hallucinations, measure answer quality trends, and build operational dashboards (Power BI, Grafana, etc.).
- Automate Evaluation Pipelines: Build reusable test harnesses and integrate automated evaluation/regression checks directly into CI/CD release gates.
- Responsible AI & Compliance: Evaluate applications for potential bias, unfair treatment, compliance issues, and data privacy risks within regulated environments.
- Cross-Functional Partnering: Translate business expectations into measurable technical criteria alongside engineers, data scientists, and business stakeholders.
