Remote AI training and data labeling jobs

Operational health physicists from DOE sites, national labs, reactors and decommissioning projects 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.

Named RSOs and radiation protection managers on broad-scope, hospital, university or industrial licences 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.

Umbrella listing for Mercor's radiological safety red-team panel: RSOs, health physicists, source security, emergency response and nuclear medicine specialists write prompts, judge frontier AI replies against a policy standard, and write reference answers. Remote contract at $65–75 per task; 8 hired this month.

RF, microwave, antenna and electromagnetics engineers solve and critique hard technical problems for a short-term expert evaluation project: analysing systems and trade-offs, checking calculations and assumptions, and writing rigorous explanations. Hands-on industry experience and an EE-family degree. Remote hourly contract at $80–95/hour.

Senior materials scientists, and electrical or mechanical engineers, author realistic tasks with a prompt, a data room and a grading method, run them against an AI model and tighten them until the model can no longer reason through cleanly. Daily onboarding and office hours. Remote hourly contract at $60–90/hour.

Turn real lab and test-bench experience into AI benchmark tasks: build test logs, calibration records and failure reports, define the right diagnosis, and write 35+ point rubrics. Remote contractor, $30–70/hour paid per accepted task, 50 openings, 4+ years in test or production.

Annotate and score robotics video footage against a scoring guide: label actions, objects and events, rate clips for quality and relevance, and QA your own annotations. Mid-level annotation experience preferred, robotics footage experience heavily preferred. Flat $7/hour, 20 openings, remote contract.

Mechanical designers build and validate parametric FreeCAD models of parts and assemblies, applying GD&T, to create a CAD dataset for AI training. Optional Python scripting. Remote contractor role, 50 openings, $40–100/hour.

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.

Open multi-part assemblies in FreeCAD, work out their design intent, and write several exact-answer technical questions per assembly that a model cannot guess its way through. Fifty openings, flagged high demand, contractor at $40–80/hour. FreeCAD experience helps but is not required.

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.

Complete real PCB workflows in Altium Designer on screen recording (schematics, layout, placement, routing, validation), then write prompts and rubrics from them so AI agents learn to use the tool. Needs your own Altium access and prior human-data experience. 40 openings, $90–175/hour.

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.

Model production-ready parts and assemblies in FreeCAD or similar parametric CAD, with GD&T drawings and DFM checks, as reference material for AI training. Remote contractor, $40–100/hour, 50 openings, 2+ years designing for manufacture.

CAM programmers and CNC machinists fluent in Autodesk Fusion 360: review AI-generated manufacturing advice and build the rubrics that grade it for accuracy and efficiency. Per-task pay with weekly minimums. 100 openings, contractor, $60–100/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.
