Statistician & Experimentation Expert

What you'll do

You build the statistics scenarios that AfterQuery's AI lab customers use to test model reasoning, focused on causal inference and A/B testing. The ad lists four tasks: author realistic scenarios from study design through analysis and interpretation; write reference answers with the statistical reasoning behind each modeling choice; grade model output for methodological soundness and correct interpretation; and flag analyses that read as rigorous but draw invalid conclusions.

The last point is the heart of it: a model can produce confident statistical prose with a flawed design underneath, and you are the check.

Who fits

• An advanced degree in statistics, biostatistics or a closely related quantitative field
• 2+ years of applied statistics or experimentation experience
• Depth in experimental design, causal inference or A/B testing
• Fluency in R or Python for statistical analysis
• Able to commit at least 10 hours per week
• Preferred: a PhD in statistics, biostatistics or econometrics; experience running large scale experimentation platforms; Bayesian methods or advanced causal inference such as instrumental variables or synthetic control

What it pays

The board headlines $115/hr. The ad's contract section states $80 to $150/hr, paid weekly via Stripe, and says your rate is set from your experience and not negotiated down after you start. This listing records the $80 to $150 range.

How hiring works

The ad lists five steps: apply (about five minutes, a resume plus a few structured questions); resume review against a published rubric, with a decision on every application; a written assessment you may be asked to take for further placement; onboarding, where you sign the contractor agreement, connect Stripe and get platform access; and a project match, usually within a week of onboarding.

Worth knowing

Good:

• A wide stated range with a high ceiling, and weekly pay
• Remote and fully async with no fixed hours, a 10 hour minimum and no maximum
• The ad states there is no screen recording, keystroke monitoring or idle timers
• Ongoing project work rather than single task batches

Less good:

• An advanced degree is required, which rules out experienced analysts without one
• A 10 hour weekly minimum applies
• The assessment is described as something you "may" be asked to take, so reaching a first project is not guaranteed
