Mechanical Engineer Reviewer

Pay: $90/hour
Commitment: Hourly, ~40 h/week

Role Overview

• Mercor is seeking senior mechanical engineering professionals to review evaluation tasks for AI systems operating in Fortune 500 enterprise product design and manufacturing contexts.
• The workflows are calibrated to the design complexity, safety stakes, and production scale of Fortune 500 and large industrial manufacturers.
• This role reviews worlds on two standards tracks: a US track (ASME) and an International track (ISO). Experts qualified in either or both tracks are encouraged to apply.
• Reviewers assess enterprise mechanical engineering scenarios, reference outputs, and grading rubrics that capture how senior F500 engineering leaders think.

Key Responsibilities

• Review mechanical engineering tasks, reference outputs, and supporting artifacts for technical accuracy, realism, and professional complexity.
• Independently check engineering calculations, design assumptions, analyses, and conclusions against the applicable standards track.
• Review design documentation and relevant CAD or simulation evidence to identify errors, omissions, and inconsistent assumptions.
• Evaluate grading rubrics for clarity, specificity, and whether they distinguish sound professional engineering judgment from generic textbook recall.
• Provide clear written feedback and verify that revisions resolve the identified issues.

Ideal Qualifications

• 5+ years working as a mechanical engineer or engineering lead at a Fortune 500 or major industrial, automotive, aerospace, or manufacturing company (GE, Boeing, Caterpillar, Ford, Honeywell, Siemens, Bosch, Rolls-Royce, Mitsubishi Heavy Industries).
• Direct ownership of large-scale product designs, manufacturing processes, or engineering certification programs.
• Fluency in enterprise mechanical engineering tooling and methodologies, plus understanding of how safety standards, regulatory certification (ASME, ISO, FAA, FDA), and cross-functional design governance actually work.
• A professional engineering credential (US PE or an international equivalent such as CEng or EUR ING) and prior rubric, engineering-training curriculum, or design documentation authorship are a plus.
