Do you trust artificial intelligence companies to provide stable, secure employment for workers?

Artificial intelligence labs are hiring subject matter experts, including civil rights attorneys and software engineers, to evaluate and refine AI models. This emerging labor sector tasks professionals with solving engineering problems and grading generated content.

Why it matters

Developers require high-level human oversight to test and verify AI outputs, driving demand for specialized expertise. This reliance on expert-generated training material is fueling growth in the data annotation job market.

Professional roles in AI training command high premiums, with civil rights attorneys earning $400 an hour and software engineers earning $120 an hour. These figures are significant when compared to the average $110 hourly rate for general Mercor workers.

The players

Mercor is an artificial intelligence firm currently facing class action lawsuits over data privacy concerns.

Deeptune

Deeptune is an organization that was acquired by Mercor on July 9, 2026.

Jack Weis

Jack Weis is a Princeton graduate who sought employment as a contract worker within the AI industry.

Nvidia

Nvidia is a technology corporation reportedly in discussions to participate in a funding round for Mercor.

The details

Contractors solve complex engineering problems and assess medical explanations to create reliable reference datasets. While firms like Mercor offer high pay, the sector faces employment instability and legal challenges regarding data privacy.

Timeline

Macro View

The hiring surge for subject matter experts follows the upward trajectory of AI-related roles identified in LinkedIn's 2026 report on the fastest-growing U.S. jobs. This expansion mirrors previous labor shifts where technological adoption necessitated new categories of highly specialized work.

The shift toward AI training as a viable career path offers new income opportunities for professionals with specialized knowledge in law or engineering. However, workers should remain cautious regarding the job instability and privacy litigation that currently characterize the contracting environment at firms like Mercor.

The takeaway

Workers seeking roles in AI training should carefully vet company practices regarding data privacy and contract duration. Developing specialized domain knowledge in areas like civil rights or software engineering remains the most effective strategy for securing the highest pay rates in the industry.
