The reviewer seat on micro1's physics work: critique derivations and arguments written by researchers or AI, find the errors and unjustified steps, and write precise feedback, cross-checking in SymPy and Python. Postdocs and junior faculty, US, Canada and UK focused. 30 openings, contractor, $80–150/hour.

Explain physics to an AI and grade what it writes back: write clear explanations of hard concepts, build physics training material, and review model output for conceptual accuracy. A physics PhD is the preferred bar. 100 openings, contractor, $70–90/hour, fully remote.

Research-level AI training work on magnetic order: magnetic structure factors, propagation vectors, magnetic space groups in BNS notation checked against MAGNDATA, AFM/FM classification, neutron scattering and MOKE signatures. Ten openings, contractor, $80–160/hour, remote.

Umbrella listing for Mercor's chemistry red-team panel: synthetic, analytical, forensic, defence and process safety chemists write benign, dual-use and adversarial prompts, judge frontier AI replies against a policy standard, and write reference answers. Remote contract at $65–75 per task; 5 hired this month.

Red-team frontier AI models on chemical misuse: write benign, dual-use and adversarial prompts from trace analysis and method validation, judge responses against a policy standard, and write reference answers. Remote contract at $65–75 per task.

Write and review evaluation tasks that make an AI derive, reproduce or validate clinical trial statistics from TFLs and CDISC datasets, and catch mismatches between outputs, the SAP and the CSR narrative. Remote contractor, $60–65/hour, 30 openings; 5+ years in clinical trials and SAS or R preferred.
