Job description

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. OpenTrain AI hires and contracts contributors for specialized projects where human expertise helps improve next-generation artificial intelligence systems.

As an OpenTrain contributor, you can build a professional profile around your AI training experience and find projects that match your technical background. Creating an OpenTrain account is free.

About AI Training Work

AI systems learn from carefully prepared examples, including technical questions, answers, evaluations, and other human-reviewed content. Subject-matter experts help make these examples accurate, objective, and useful for training and assessing AI models.

This role brings engineering expertise into a fast-growing area of technology. It is remote and structured as flexible, part-time work for contributors who can dedicate at least 20 hours per week.

The Role

OpenTrain is seeking a FreeCAD CAD Question Author to create high-quality training content from multi-part CAD assemblies in native FreeCAD format. You will examine geometry, assembly relationships, engineering function, and related design information, then turn those findings into precise questions with exact, verifiable answers.

The role is listed as entry level, but it requires substantial technical knowledge and the ability to analyze complex mechanical designs. It is especially suited to an expert or consultant with strong technical communication, accuracy, and clarity.

• Work type: Part-time contractor
• Time requirement: 20+ hours per week
• Pay range: $40 to $80 per hour
• Working language: English
• Core subject: Mechanical CAD question authoring

What You'll Do

You will develop objective, precise, and non-guessable question-and-answer sets from multi-part FreeCAD assemblies. Each answer must be grounded in the design and verifiable from the available technical information.

You will also communicate clearly while clarifying requirements, responding to review feedback, and documenting insights or ambiguities that arise during the authoring process.

• Analyze complex mechanical designs, including geometry and assembly relationships.
• Interpret engineering function and related design information.
• Create several technical questions for each CAD assembly.
• Write clear, technically accurate questions and answers.
• Ensure every answer is objective and verifiable from the design.
• Document ambiguities and useful insights discovered during authoring.
• Communicate technical concepts in writing and verbally.

Requirements

You should have an extensive background in mechanical engineering, aerospace engineering, or industrial design, together with strong foundational CAD knowledge. Experience analyzing multi-part assemblies and interpreting engineering drawings is required.

Direct FreeCAD experience is valuable, while comparable experience with another CAD platform can also support success. You must be able to turn complex technical concepts into detailed engineering questions and training material.

• Expertise in mechanical engineering, aerospace engineering, or industrial design
• Experience with multi-part CAD assemblies
• Experience interpreting engineering drawings
• Familiarity with FreeCAD or a comparable CAD platform
• Ability to author precise, technically verifiable engineering questions and answers
• Strong written and verbal communication skills
• Meticulous attention to technical accuracy and detail

Who Should Apply

This opportunity may suit a mechanical engineer, aerospace engineer, industrial designer, CAD specialist, or technical consultant who enjoys analyzing designs and explaining how they work. It is a strong fit for someone who can distinguish objective engineering facts from assumptions and express those facts with precision.

English communication is required for the project. The role is available across the countries specified in the listing and offers a substantial part-time commitment for qualified contributors.

• Experienced CAD users who understand multi-part assemblies
• Engineers comfortable explaining geometry, function, and design relationships
• Technical contributors who write detailed assessment material
• Experts who value clarity, accuracy, and verifiable answers
