Accountabilities

The role focuses on ensuring the quality, reliability, and safety of advanced AI models through comprehensive evaluation and testing processes.

You will collaborate on identifying weaknesses, improving evaluation methodologies, and creating actionable insights that enhance model performance.

• Evaluate large language models across areas such as factual accuracy, reasoning quality, hallucination detection, safety, and reliability.
• Design and execute test plans, regression suites, and evaluation frameworks to measure model performance.
• Identify and document model failures, including prompt vulnerabilities, incorrect outputs, bias issues, and reasoning inconsistencies.
• Develop clear evaluation rubrics, pass/fail criteria, and quality benchmarks for AI system assessment.
• Perform adversarial testing, red-teaming exercises, and robustness evaluations to identify potential risks.
• Verify grounding, retrieval-augmented generation outputs, tool usage accuracy, and workflow reliability.
• Analyze model behavior and provide recommendations for improving prompts, guardrails, and evaluation strategies.
• Support automation initiatives using tools such as Python or SQL to improve testing efficiency.
• Maintain detailed documentation of findings, root-cause analysis, and reproducible issue reports.
• Collaborate with technical teams to improve AI evaluation metrics, dashboards, and quality monitoring processes.

Requirements

The ideal candidate brings strong experience in AI quality assurance, machine learning evaluation, software testing, or related technical disciplines.

You should be comfortable analyzing complex AI behaviors and communicating technical findings clearly.
