OpenTrain AI is the hiring and contracting organization for this role. We focus on long-term, flexible opportunities where contributors gain experience, build a portfolio, and shape how modern AI behaves.

About AI training and why it matters

AI training (data labeling/annotation) is the human side of building intelligent systems. Expert reviewers and creators supply the high-quality examples and corrections that models learn from — everything from drawings and schematics to technical notes and manufacturability guidance.

This work is remote and flexible, often accessible without prior industry connections. For technical contributors, projects offer a chance to apply domain skills (CAD, GD&T, electrical design, PCB layout) to influence how future tools interpret and generate engineering documentation.

The role

OpenTrain AI is recruiting an Architect CAD and Construction Documentation Reviewer to support AI training grounded in architectural and engineering documentation. You will create and review technical documentation packages, clarify requirements through exchanges, and deliver real-world examples that improve model performance.

This is a contract, part-time role targeting 20+ hours per week and available to contributors worldwide who are fluent in English.

• Employment type: Contractor, Part-time
• Time commitment: 20+ hours/week
• Language: English (advanced)
• Location: Worldwide (remote)

What you’ll do

You will produce and review multi-document technical packages used to train AI systems. Work involves a mix of hands-on CAD drafting, technical annotation, and reviewing others' deliverables to meet clarity and manufacturability standards.

• Create detailed floor plans and elevation sets based on project requirements
• Develop comprehensive 2D/3D CAD drawings for architectural and engineering purposes
• Prepare accurate GD&T callouts for manufacturing documentation
• Produce and annotate multi-sheet electrical schematics to industry standards
• Design and review PCB layouts with manufacturability and functionality in mind
• Collaborate with reviewers to clarify requirements and resolve technical questions
• Deliver thorough documentation packages aligned with milestones and quality expectations

Requirements

Candidates must have recent hands-on experience producing and reviewing architectural CAD and construction documentation and be comfortable working remotely with teams in English.

• Recent architectural CAD and construction documentation experience
• Proficiency with industry-standard 2D and 3D CAD tools and PCB layout design
• Ability to generate and interpret GD&T callouts and complex schematic diagrams
• Experience with multi-sheet electrical schematics and PCB layouts
• Strong attention to detail and organized handling of multi-document sets
• Advanced English communication skills; remote cross-functional collaboration experience is a plus
• Experience level: Entry level (recent but relevant experience expected)

Compensation, data type, and labeling activity

OpenTrain pays hourly for this role. Work focuses on document data (technical drawings, schematics, and related text) and includes both text-generation and evaluation/rating labeling activities.

• Pay: USD $40–$50 per hour (hourly rate varies by task and experience)
• Data type: Document
• Labeling types: Text generation, Evaluation/rating
