Engineering Expert

Role Overview

• Mercor is hiring experienced engineers to build and review evaluation tasks for AI agents.
• Each task is set in a realistic simulated engineering organization, with the CAD and ECAD files, drawings, specs, change requests, emails and engineering tools a design team really uses.
• You make sure each task reads like a real request, the reference answer holds up against the design files and the applicable standards, and the grading rubric checks what a senior engineer would check.

Key Responsibilities

• Refine AI-drafted task prompts so they read like a real request from an engineering lead or project manager, without giving the answer away.
• Check reference outputs against the world's files, models and standards, and correct what is wrong.
• Write and tighten grading rubrics: pass/fail criteria with exact values and tolerances, plus the judgment calls a generalist would miss.
• Read how leading AI models attempt each task and confirm they fail for fair, defensible reasons.
• Work across mechanical design (part and assembly modeling, drawings and design release, sheet metal and DFM in SolidWorks or FreeCAD; HVAC and building services), electrical design (power distribution and protection; schematics, PCB layout and manufacturing release in Altium Designer), ECAD-MCAD co-design, civil construction documents, process safety, and engineering project delivery and quality.

Ideal Qualifications

• 3+ years of professional engineering experience in mechanical, electrical, civil, chemical / process or mechatronics engineering.
• Bachelor's degree in engineering.
• Recent hands-on work in SolidWorks, FreeCAD or Altium Designer, or in power distribution, HVAC, process safety or construction documentation.
• A professional engineering license (PE, CEng, EUR ING, P.Eng) is a plus, as is prior experience on a Mercor RL project.

Details

• You start with a short onboarding session and a paid skills assessment. Once you pass, you can claim your first task right away.
• Strong performers can move into reviewer and world lead roles.
