Earth Science & Geology Expert

What you'll do

You write the geoscience problems and the answer keys that models are tested against, then grade what the models produce.

• Author realistic scenarios that run from field observation through interpretation, the kind a working geologist reasons through
• Write reference answers that show the geological reasoning, with processes and timescales weighed
• Grade model output on geoscience and climate questions for physical accuracy and sensible handling of uncertainty
• Flag explanations that read fluently but get the earth science wrong, the errors only a trained geoscientist would notice

The ad frames the work as ongoing project work rather than single task batches, and says your specialty is where you stay.

Who fits

• An advanced degree in geology, earth science or a closely related field
• At least 2 years of research, industry or field experience in the geosciences
• Depth in an area such as sedimentology, hydrology, geophysics, volcanology or climate science
• Clear written English, since the job is turning scientific judgment into reasoning someone else can learn from
• Able to commit at least 10 hours a week

Preferred: a PhD or professional geologist licensure, GIS, remote sensing or geospatial modelling skills, and energy, mining, environmental consulting or geological survey experience. The application form asks optionally for a Professional Geologist (PG / GIT) credential.

What it pays

The board headlines $85/hr. The ad's own contract section gives a range of $60 to $110/hr, set from your experience and, the ad says, not negotiated down after you start. Payment is weekly via Stripe. Working hours are your own: fully remote and async, a minimum of 10 hours a week and no maximum, with no screen recording, keystroke monitoring or idle timers. You are an independent contractor.

How hiring works

The ad lists five steps: a roughly five-minute application (resume plus a few structured questions), a resume review against a published rubric with a decision for every applicant, a possible written assessment for further placement, onboarding (contractor agreement, Stripe, platform access), and a project match in your specialty, usually within a week of onboarding.

Worth knowing

Good:

• Work stays in your specialty and is judged on scientific reasoning, not output volume
• No fixed hours and no monitoring software
• Stated weekly pay and a rate set from experience
• A wide range of qualifying subfields, from sedimentology to climate science

Less good:

• The 10-hour weekly minimum is a real commitment for anyone with a full-time job
• The rate band is wide, so the figure you get depends on how your experience is read
• A written assessment may be required, and AfterQuery's help centre says assessments are unpaid and cannot be retaken
• A project match is "usually within a week" of onboarding, not guaranteed
