- Analyze experimental results to validate these metrics, ensuring they accurately predict user satisfaction and drive product decisions

- Build and maintain the data pipelines that calculate these metrics at scale, delivering actionable quality signals to Search, Product, and model training teams

- Communicate findings and bring clarity through close collaboration with Product and Search teams

- Operate in a small, high-impact team where your work directly shapes how Perplexity measures and improves Answer Quality

Qualifications
- MS in a technical field or equivalent experience

- 4+ years of experience working as a Data Scientist, Analytics Engineer, or related role

- Experience working on search, recommendation, or LLM-based products, with an emphasis on designing online metrics and analyzing A/B experiments

- Strong proficiency in Python and SQL (expected to write production-grade code)

- Deep knowledge of statistical analysis

- Experience with Business Intelligence (BI) tools for visualization and reporting

- Comfortable with agentic coding workflows and using AI-assisted development tools to iterate faster

Preferred Qualifications
