Licensed Plumber Expert - Remote Contract
Listing checked September 22, 2026 · pay as published by AfterQuery
Overview
AfterQuery hires licensed plumbers to create diagnostic and code compliance scenarios that frontier AI labs use to test model judgment. You turn field knowledge into symptom-to-repair cases, then score how well AI answers handle plumbing codes, safety and workmanship. The work runs remote and async, about 10 hours each week, with pay each week through Stripe. Rates range from $50 to $90 per hour and reflect your license level and experience. Candidates with a journeyman or master license plus 2 or more years past apprenticeship fit best.
What You'll Do6
- 1Write realistic plumbing scenarios that move from symptom to diagnosis to repair.
- 2Draft reference answers with the code and diagnostic reasoning behind every step.
- 3Grade model output for compliance with UPC or IPC rules, safety and workmanship.
- 4Flag advice that sounds plausible but could flood a basement or poison a water line.
- 5Use field standards to judge whether an AI answer matches what a licensed plumber would do.
- 6Keep written feedback clear enough for a non-plumber reviewer to follow.
Requirements8
- 1Hold a journeyman or master plumber license in a US state or jurisdiction.
- 2Bring 2 or more years of field experience beyond apprenticeship.
- 3Apply plumbing codes such as UPC or IPC in written scenarios.
- 4Write clear English explanations of diagnostic steps.
- 5Commit at least 10 hours per week.
- 6A master plumber or plumbing contractor license gives you an edge.
- 7Depth in commercial plumbing, medical gas systems or backflow certification helps.
- 8Experience with estimating, inspection or apprentice training adds value.
Who Should Apply
Licensed plumbers with 2 or more years past apprenticeship and comfort reading UPC or IPC codes will find a strong match. The role suits someone who can walk through a diagnosis in plain written English, because each scenario needs a clear chain from symptom to repair. Candidates without an active journeyman or master license, or those who cannot show field work beyond apprenticeship, score low. A frequent rejection reason is a license that does not match a US state or jurisdiction, along with vague code citations that lack reasoning. People who want hands-on work, tools or job site travel should skip this contract.
Salary Insight
AfterQuery lists $50.00 to $90.00 per hour. That range sits above many standard plumbing field rates, which fits an expert-network model where AfterQuery sets pay from your license and experience. Master plumbers with commercial, medical gas or backflow credentials can land near the top. Pay goes out each week through Stripe.

Application Tip
Make your license the first line of your application: license type, issuing state, and license number. Then add a short writing sample that takes one diagnostic call from symptom to code citation, since the listing asks for Plumber License (Journeyman / Master) and grades your written reasoning.
