Overview

AI research teams rely on Mercor for mechanical engineering judgment that models cannot generate alone. Your design standards and analysis habits become the rubric that grades frontier AI. Mercor keeps a standing listing for mechanical engineers who want AI training and evaluation work, even when no project is active. When a project starts, matching engineers from the pool receive an invite that names the rate, hours, and client.

What You'll Do5

  • Write design problems from work you have done, covering loads, constraints, and tolerances, then supply a reference answer that anchors the model's score.
  • Grade model-written analysis, checking the free body diagram, the governing failure mode, and whether the safety factor applies to the right quantity.
  • Identify designs that pass the calculation but fail in practice because of manufacturability, assembly, wear, or thermal expansion.
  • Explain your reasoning in writing so project leads can follow the basis for each score.
  • Flag unclear task instructions and request missing constraints before starting an evaluation.

Requirements5

  • Degree in mechanical engineering plus professional experience in design or analysis.
  • A track record of designs that moved from concept to build, with lessons from how they performed.
  • Clear written communication, because most tasks require you to justify your judgment.
  • Comfort with ambiguous tasks and willingness to call out instructions that lack detail.
  • Working knowledge of loads, constraints, tolerances, failure modes, and safety factors.

Who Should Apply

Mechanical engineers with hands-on design or analysis experience fit this pool best. You have seen a design get built and learned what happened after assembly, wear, or thermal cycling. The role suits people who can write precise explanations and who notice when a task brief leaves out a critical constraint. Candidates who only hold a degree without professional design work often score low, and applicants who give vague answers in the AI interview struggle to match. Another common rejection reason is failing to show how your judgment applies to real hardware rather than textbook problems.

Salary Insight

Past projects paid between $70 and $125 an hour, with Mercor setting each rate by scope and depth. Complex grading work or design problem writing tends to land at the higher end, while shorter reviews sit lower. This range matches senior contract mechanical engineering work and specialized AI evaluation, not entry-level annotation.
