AI Data Analyst

Job Summary

Glean is seeking an AI Data Analyst to help power the human evaluation system behind Glean s AI product quality.

This role sits at the centre of response quality, competitive benchmarking, and release readiness. You will evaluate AI outputs, label and categorize failure modes, maintain high-quality benchmark data, and help ensure the datasets and evals we rely on are realistic, consistent, and tied to measurable product quality lift.

This is a highly cross-functional role. You will work closely with QA, Engineering, Product, and the evals team to convert ambiguous quality issues into structured data, actionable feedback, and repeatable quality signals.

You will:

• Run ongoing human labeling for priority AI workflows, including response quality, task success, MCP and tool use, end-to-end Cowork-style workflows.
• Triage bad-query reports, downvotes, escalations, and routed quality issues; categorize failure modes and feed clean analysis back to partner teams.
• Perform qualitative analysis to identify recurring patterns such as hallucinations, retrieval failures, tool-use issues, weak grounding, and poor workflow completion.
• Follow and improve labeling guidelines and rubrics so judgments are consistent, realistic, and useful for model and product improvement.
• Maintain high-quality labeled datasets, golden sets, and regression slices; monitor coverage, drift, leakage, and difficulty distribution.
• Participate in calibration exercises with human graders and validate LLM-as-a-judge outputs against human labels to improve consistency and judge quality.
• Partner with engineers, PMs, QA, and eval owners on pre/post-change quality reads, benchmark updates, and release-readiness decisions.
• Contribute to recurring quality reporting by surfacing top failure modes, coverage gaps, quality shifts, and actionable recommendations.

About you:

• 3-5 years of experience in data labeling, data analysis, QA, or a related field.
• Strong analytical judgment and attention to detail, with the ability to apply nuanced rubrics consistently.
• Experience evaluating AI-generated outputs or working with NLP, search, recommendation, or other ML systems.
• Familiarity with structured qualitative analysis, basic SQL/data retrieval, and spreadsheet-based workflows.
• Clear written and verbal communication skills, with the ability to explain findings to both technical and non-technical audiences.
• Ability to work independently in ambiguous, fast-moving environments and collaborate effectively across functions.

Location:

This role is hybrid (4 days a week in our offices).
