## Description

Perplexity is looking for an experienced analyst to help us build and improve our core search technologies. You'll work at the intersection of data analysis and engineering - designing metrics, building data pipelines, and improving the quality of our search and answer systems.

 - Proficiency with SQL and Python

 - Demonstrated hands-on experience with at least one of the following:

 - Building labeling pipelines using LLM-as-a-judge

 - Training ML models that shipped to production with measurable metric improvements

 - Designing evals with known ground truth (e.g. SimpleQA, BrowseComp) or driving meaningful improvements on such evals
