How this pay compares

At $135/hr (the midpoint of $85 to $185), this role pays more than 93% of the 207 open engineering roles with a listed pay range, above the median of $80.

Open engineering roles that ask for a PhD have a median of $94/hr (34 roles).

Among platforms with 10 or more priced engineering roles, Mercor has the highest median ($88/hr across 35 roles) and micro1 the lowest ($60/hr across 28).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 11 days ago.

Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

Tax
Contract pay arrives with no tax withheld. A US contractor at this rate and these hours would set aside about $2,218 a month for self-employment tax plus federal income tax at the 12% bracket (25%, before state tax). Outside the US, your own country's rules apply.

The work

You will create and evaluate difficult technical problems used to train AI systems. The work calls for real semiconductor engineering judgment, complete solutions, and clear standards that separate correct answers from plausible errors.

  • Design semiconductor engineering problems using realistic constraints and supporting data.
  • Provide technically correct solutions with reasoning another engineer can verify.
  • Define objective criteria for deciding whether an answer is correct.
  • Review other contributors’ problems for technical accuracy and sound methods.
  • Identify problems that are ambiguous or cannot be graded reliably.
  • Evaluate technically plausible answers using hands-on knowledge from at least one semiconductor area.

The hiring platform's application for this job asks for your resume, your LinkedIn profile, your phone number, your location and answers to 8 screening questions.

About AI training work

AI training is the human work behind systems that learn from examples, including writing, reviewing, and rating model answers. Experienced specialists are needed to judge complex technical work and help distinguish reliable answers from convincing mistakes.
