About OpenTrain
OpenTrain is the centralized, open platform where AI training and data-labeling freelancers find work, consolidate opportunities across platforms, and build a unified AI training portfolio they control. We make specialized AI training work easier to track, apply for, and grow into a durable freelance career.

About this role
OpenTrain is recruiting for a contract FreeCAD Expert with a BIM and IFC focus to contribute domain expertise to next-generation AI training systems. In this remote role, you will apply your deep FreeCAD knowledge to produce high-quality parametric models, BIM-structured building components, and supporting documentation that helps AI models learn, reason, and perform. No prior AI experience is required; your CAD and BIM expertise is the primary qualification.

What you will do
- Lead full parametric modeling projects in FreeCAD from conception through production-ready deliverables
- Coordinate and document building models (walls, slabs, structures) using BIM and IFC within FreeCAD
- Import, export, and validate IFC data to ensure interoperability with other CAD/BIM platforms
- Develop and manage constrained sketches, parametric model trees, and building components across project lifecycles
- Prepare technical documentation sets including drawings and model exports (STEP, STL, DXF, IFC)
- Articulate modeling strategies, BIM structuring choices, and workflow rationale in written documentation and verbal recordings to support AI learning objectives

Required skills
- Expert-level proficiency in FreeCAD with a strong portfolio of complex, completed projects
- Proven experience managing full parametric 3D CAD workflows from concept to production
- Deep practical knowledge of BIM methodologies and IFC standards, including relevant FreeCAD workbenches
- Hands-on experience with building elements, model structuring, and data management for interoperability
- Solid skills in AutoCAD, CAM, and other 3D CAD software environments
- Exceptional written and verbal communication with strong attention to detail in documentation

Helpful background
- Experience contributing to FreeCAD's open-source community or developing custom add-ons
- Background in AI, machine learning projects, or technical knowledge capture
- Familiarity with workflows bridging FreeCAD to other BIM/CAD platforms

Schedule and location
This is a fully remote contract position. Candidates are asked to specify their availability in hours per week during the application process.
