We’re hiring a CAD/3D Engineer to develop and validate simulation-ready 3D assets. This role focuses on creating high-fidelity models and performing QA/QC to ensure assets match real-world objects in geometry, scale, surface characteristics, and material definitions. You’ll also support integration into an existing Blender-based pipeline and help maintain modeling standards.

Key Responsibilities
1) CAD Modeling & Asset Development

• Build high-fidelity 3D models of vehicles (ground/air/sea) and infrastructure/environment assets.
  
• Create clean, simulation-ready meshes (STL/OBJ/FBX as needed) with correct scale, orientation, and naming.
  
• Maintain Levels of Detail (LOD) for performance and scalability.
  
• Model from technical references, drawings, images, and public/open-source materials.
  

2) Asset QA/QC & Validation (Primary Focus)
Verify assets against references for dimensional accuracy, proportions, key features, and assemblies.
Ensure mesh integrity: watertight/manifold (when required), correct normals, consistent topology, and no self-intersections.

• Validate and document surface/material properties used in simulation/rendering (e.g., material categories, roughness/metalness/specular conventions, surface smoothness).
  
• Establish QC checklists and acceptance criteria for assets (units, pivot/origin, LOD consistency, naming, hierarchy, metadata).
  
• Identify and resolve geometry/material issues causing artifacts in downstream rendering/simulation outputs.
  

3) Pipeline Integration & Automation Support

• Integrate assets into an automated Blender-based pipeline and standardized scene conventions.
  
• Use parameter-driven configs (e.g., YAML/JSON) as part of the asset ingestion workflow.
  
• Write small Python scripts/utilities for export automation and validation checks.
  
• Support minor fixes/maintenance to existing asset tooling and documentation.
  

4) Documentation & Standards

• Maintain asset preparation guidelines: modeling rules, export settings, QC procedures, and versioning practices.
  
• Create example assets/templates to help standardize future model creation.
  

Requirements
Must Have
Strong CAD/3D modeling experience (SolidWorks / Fusion 360 / Rhino / Blender or similar).
Strong understanding of mesh topology, geometric accuracy, and clean export practices.

• Experience exporting STL/OBJ (and ideally FBX/GLTF) with consistent scale and orientation.
  
• Blender experience (modeling + scene organization); basic knowledge of materials/shaders is a plus.
  
• Ability to perform structured QA/QC using references (drawings, photos, specs) and produce clear validation reports.
  
• Basic Python scripting for automation/validation (mesh checks, naming rules, export helpers).
  

Nice to Have

• Familiarity with ray-tracing/rendering workflows or physics-based simulation constraints.
  
• Experience with large assemblies, vehicles, or infrastructure-grade models.
  
• Git/version control and asset versioning discipline.
  
• Experience building internal standards/checklists for asset production.
