What You'll Do

Mercor is partnering with leading AI labs to advance frontier agent evaluations in data science and analytics. As a Data Science Expert, you'll design realistic, end-to-end data workflows that today's best models still struggle with, then grade how agents handle them. Expect to build scenarios across analytics and business intelligence (SQL analysis, dashboard builds, metric definition, A/B test design and readout, funnel and cohort analysis, ad-hoc business questions) and data engineering (ETL/ELT pipelines, dbt models, data quality monitoring, warehouse schema design, Airflow/Dagster DAGs). These scenarios will be challenging and take long sessions of focus.

Who We're Looking For

• 3+ years as an analytics engineer, BI analyst, data scientist, or data engineer at a product or consumer company
• Working fluency in at least two of: advanced SQL, dbt, warehousing (Snowflake, BigQuery, Redshift), experimentation (A/B tests), pipeline orchestration (Airflow, Dagster), metric modeling, Python for analysis
• Comfortable reading and producing data artifacts: SQL queries, dbt models, experiment readouts, dashboard specs, schema diagrams
• Clear written communication; able to articulate reasoning and data decisions step by step
• Drawn to long-horizon, challenging problem sets rather than one-off microtasks

Contract and Payment Terms

• You will be engaged as an independent contractor.
• This is a fully remote role that can be completed on your own schedule.
• Projects can be extended, shortened, or concluded early depending on needs and performance.
• Your work at Mercor will not involve access to confidential or proprietary information from any employer, client, or institution.
• Payments are weekly on Stripe or Wise based on services rendered.
• Please note: We are unable to support H1-B or STEM OPT candidates at this time.
