Overview

AfterQuery builds the expert evaluation data that frontier AI labs use to measure what their models can and cannot do, and this contract seat sits on the statistics side of that pipeline. You write causal inference and A/B testing scenarios that a model has to reason through, then judge how well it handles experimental design, analysis and interpretation. Work runs async with no fixed schedule beyond a 10 hour weekly floor, and the rate lands between $80 and $150 per hour depending on your background. Practitioners from biostatistics, econometrics or applied experimentation bring the judgment that makes these evaluations worth running.

What You'll Do5

  • Build study scenarios that track real statistical practice, from the design stage through analysis and final reading of results.
  • Draft model answers that lay out the reasoning behind every modeling decision you make.
  • Review model responses for sound method and for a correct interpretation of the numbers.
  • Call out analyses that look rigorous on the surface but rest on invalid conclusions.
  • Work inside your specialty, whether that means experimental design, causal inference or A/B testing, and shift weekly hours up or down as project work allows.

Requirements8

  • Advanced degree in statistics, biostatistics or a closely related quantitative field.
  • Two or more years of applied statistics or experimentation work.
  • Depth in experimental design, causal inference or A/B testing.
  • Fluency in R or Python for statistical analysis.
  • Capacity to commit at least 10 hours per week.
  • Preferred: PhD in statistics, biostatistics or econometrics.
  • Preferred: experience running large scale experimentation platforms.
  • Preferred: Bayesian methods, instrumental variables or synthetic control.

Who Should Apply

The statistician who fits here holds a graduate degree in a quantitative field and has spent two or more years running experiments or causal analyses in practice. You can defend a modeling choice in writing and catch a flawed conclusion buried inside a polished report.

Salary Insight

The listing shows $80 to $150 per hour, paid weekly through Stripe, with the number set from your experience at sign-up instead of negotiated down later. The $115/hr midpoint fits a specialist with a graduate degree and a few years of applied experimentation behind them, while PhDs and people who have run large scale experimentation platforms usually land near the top of that band.
