Remote AI training and data labeling jobs

Engineers with problem-setting credentials (olympiad committees, licensure exam items, qualifying exams) write hard technical problems in aerodynamics, materials, CAD, circuit design or mechanical engineering, and grade AI answers to them. 47 openings, paid per accepted task, $60–110/hour band.

Inventor modellers wanted for a FreeCAD project: build parametric parts and assemblies from briefs, keep edits parametric, audit models against GD&T and DFM criteria, and produce and read technical drawings. 4+ years for edit work, 10+ for complex creation. $30–100/hour, 29 openings.

Solve and grade hard mechanical design problems (GD&T per ASME Y14.5, tolerance stack-ups, DFM, drawing release) and check AI answers for engineering correctness. Five years of production design ownership asked for; problem-authoring credentials strongly preferred. $60–130/hour, paid per accepted task, 25 openings.

Experienced Fusion 360 CAM programmers create 3, 4 and 5-axis toolpaths, tune post-processors, and write instructional material on CAM best practice for AI training. Five years required. Remote contractor role, 10 openings, $80–120/hour.

Control engineers design and tune PID, LQR, MPC and Kalman controllers in Python, model plants from first principles, and document the decisions for an AI training project. Contractor, remote, 10 openings, $30–50/hour. Five years of controller design deployed on real hardware.

Device physicists and process engineers write explanations, technical assessments and structured feedback on semiconductor physics, microfabrication, scaling and reliability for AI training. A Master's or PhD is preferred. Twenty-five openings, paid per accepted task, $66–130/hour band.

Solve advanced computational fluid dynamics problems (meshing, turbulence modelling, multiphase flow, heat transfer, solver setup), then judge whether AI-generated answers are engineering-sound and write up what is wrong when they are not. Three years of validated simulation work is the bar, not AI experience. Remote contractor engagement.
