You’ll write hard, verifiable engineering problems drawn from your own specialty, work out the answers yourself, and show us exactly where today’s AI systems still fall short of a practicing engineer.</p><p>This is a fast-growing area focused on teaching AI to reason like an engineer. Models can already talk fluently about mechanical engineering — what they can’t yet do reliably is the actual work: size a component against a real load case, catch the failure mode a spec sheet doesn’t mention, read a CAD assembly and tell you what interferes at full travel, or predict what a design change breaks downstream. Your engineering judgment becomes the benchmark those models are measured against.</p></section><section class="rd-section"><h2>What you’ll actually do</h2><ul><li><b>Write challenging, closed-ended problems</b> from your area of expertise — mechanical design and CAD, structures and materials, thermal and fluids, dynamics and controls, or manufacturing — built so that solving them takes real engineering reasoning, not a lookup.</li><li><b>Derive and verify the correct answer</b>, and write a worked solution showing how you got there.</li><li><b>Test your problems against AI systems</b> and sharpen the ones they get right until they challenge the model.</li><li><b>Review AI-generated analysis, designs, and technical documentation</b> for correctness and real-world applicability.</li><li><b>Review other contributors’ problems and solutions</b> for correctness, ambiguity, and rigor.</li></ul></section><section class="rd-section"><h2>Roles this fits</h2><p>Common backgrounds: Mechanical Designer, CAD Designer, Drafter.</p></section><section class="rd-section"><h2>What we look for</h2><ul><li>2+ years of professional mechanical engineering experience in any specialty: design, product development, manufacturing, thermal, structural, automotive, aerospace, HVAC, robotics, or energy.</li><li>Fluency in the tools of your specialty — CAD (SolidWorks, Fusion 360, Onshape, Creo, NX, CATIA, or Inventor), FEA/CFD, or MATLAB/Python for engineering analysis.</li><li>Strong fundamentals across mechanics of materials, dynamics, thermodynamics, heat transfer, fluid mechanics, and manufacturing processes.</li><li>Able to write a precise, unambiguous technical problem and a clear worked solution in fluent written English.</li><li>Meticulous — you check your own work and enjoy finding the edge case that breaks an assumption.</li><li>A bachelor’s degree in mechanical engineering or a related field (completed or in progress).</li><li>Based in the United States, Canada, or the United Kingdom.</li></ul></section><section class="rd-section"><h2>How it works</h2><div class="rd-steps"><div class="rd-step"><span class="rd-step-n"></span><h3>Apply</h3></div><div class="rd-step"><span class="rd-step-n"></span><h3>Qualify</h3></div><div class="rd-step"><span class="rd-step-n"></span><h3>Work & get paid</h3></div></div></section><section class="rd-section"><h2>Compensation</h2><p>Up to $75 – $125+/hr depending on task difficulty and specialization.
