Open globally, about 15 hours a week, per-task pay. 10 openings, $50–100/hour.

Model simple mechanical components in SolidWorks, NX, Creo or CATIA, interpret drawings and tolerances, and critique AI output on CAD and conceptual FEA questions. Remote contractor, $55–100/hour, 50 openings. The preferred bar is 5+ years of hands-on design engineering.

Create, solve and validate structural, thermal and multiphysics engineering tasks end to end in Python with open-source solvers and coding agents. Global remote contractor, $80–150/hour paid per accepted task, about 15 hours a week, 100 openings. MS/PhD, or BS plus 1–2 years.

Review AI-generated advice on CAM, CNC and Fusion 360 manufacturing workflows, and write the rubrics that grade it for accuracy and efficiency. Teaching experience is highly preferred. $60–120/hour, paid per accepted task, open worldwide, 20 openings.

Write exact, verifiable question-and-answer sets about multi-part mechanical assemblies supplied as native FreeCAD files, for an AI training project. Mechanical, aerospace or industrial design background; direct FreeCAD use is a plus, not a must. 30 openings, contractor, $40–80/hour.

Umbrella listing for Mercor's nuclear red-team panel: fuel-cycle engineers, safeguards inspectors, nuclear security, forensics and nonproliferation specialists write prompts, judge frontier AI replies against a policy standard, and write reference answers. Remote contract at $65–75 per task; 21 hired this month.

Open native FreeCAD files of multi-part aerospace assemblies and write hard, non-guessable questions about them, each with an exact, sourced answer. Built for mechanical, aerospace and industrial design backgrounds; FreeCAD itself is a plus, not a requirement. $40–80/hour, 50 openings, contractor, remote.

Materials science PhDs author original, executable research problems for a scientific-computing AI benchmark, with depth in both semiconductor materials and molecular modeling. Tasks ship only when frontier models fail them more often than not. 6 weeks, 20+ hours a week, Git and Docker workflow. $70/hour, 212 hired this month.

Radiological emergency planners, field monitoring teams and consequence modellers red-team frontier AI models: write benign, dual-use and adversarial prompts, judge model replies against a policy standard, and write reference answers. Remote contract at $65–75 per task.

Remote hourly contract for FPGA, digital design and embedded hardware engineers who already run Intel/Altera Quartus II on their own Windows PC. $55–65/hour, paid weekly via Stripe or Wise, $10 more than the sister Vivado listing. Needs a display above 2.5 megapixels.

Build, run and validate scripted CFD cases (airfoils, meshes, boundary conditions, lift and drag) so an AI can learn to do engineering simulation from the command line. Python-heavy, with coding agents expected. $80–150/hour, paid per accepted task, about 15 hours a week, open globally.

Build, modify and QA parametric CAD models and assemblies in FreeCAD, apply GD&T and DFM, and produce technical drawings, all as training input for AI systems. Two years of mechanical or product design experience; Python CAD scripting preferred. 50 openings, $40–100/hour.

Solve hard analog, digital, mixed-signal, power and RF design problems and grade AI answers to them for technical correctness. Senior bar: MS/PhD or BS plus 8 years, five years of hands-on design with production or tape-out. Paid per accepted task, quoted at $60–130/hour. 25 openings.

Build and verify AI training tasks in analog, digital, power, mixed-signal or RF design: write netlists or HDL, run simulations from the command line, and script it all in Python with coding agents. Paid per accepted task, quoted at $80–150/hour. Around 15 hours a week, global, 100 openings.

Remote hourly contract for FPGA and RTL engineers who already have AMD/Xilinx Vivado running on their own Windows PC. $45–55/hour, paid weekly via Stripe or Wise. You supply the tool, the hardware and a screen above 2.5 megapixels; the tasks themselves are not described.
