Job Description

Job Summary

Description

In this role, you will:

  • Build and operate AI evaluation workflows that measure the quality of LLM outputs across chat,

summarization, recommendations, and agent-based features.

  • Implement LLM-as-a-Judge and rubric-based evals to score outputs for correctness, relevance, grounding,

and consistency.

  • Instrument LLM and agent workflows to capture traces, prompts and responses, metadata, and user

feedback.

  • Support release readiness by running evals before launches and highlighting regressions or quality risks.
  • Help define agent-specific evals (task completion, tool correctness, error recovery).
  • Partner with AI engineers and AI platform teams to translate product requirements into evals criteria.
  • Review eval results and recommend improvements.
  • Contribute to system design for observability, retries, and logging.
