The role involves 3D modeling, texturing, material creation, lighting, rendering, and optimization of assets for real-time visualization platforms.\nKey Responsibilities\nCreate and optimize 3D assets (industrial equipment, factory environments, vehicles, robotics, port infrastructure) for use in OpenUSD/Omniverse-based digital twins, and various other systems.\nConvert CAD data (STEP, IGES, SolidWorks, native mechanical formats) into simulation-ready (\"SimReady\") USD assets\nBuild and maintain material libraries with physically accurate PBR properties (not just visual materials: properties that inform collision, friction, and sensor simulation)\nPerform poly reduction, retopology, and LOD (level-of-detail) generation while preserving UVs, collision geometry, and semantic structure\nSet up collision meshes, physics proxies, and joint/articulation rigging for simulated machinery, robots, and AMRs\nTag assets with semantic metadata (asset class, function, material type) to support AI-driven asset retrieval and scene understanding\nCollaborate with simulation engineers to validate that assets behave correctly under physics simulation (mass, inertia, contact behavior)\nWork within a structured versioning/lineage pipeline: every asset needs traceable provenance, not just a final export\nSupport real-time performance targets: assets must render and simulate efficiently in live Omniverse sessions, not just look good in isolation\nTroubleshoot and document pipeline issues (e.g., mesh count inconsistencies, instancing failures, format-conversion artifacts) in collaboration with pipeline engineers\nSkill Requirements\nStrong experience with Blender, Autodesk Maya, 3ds Max, or similar 3D tools.\nHands-on experience in 3D modeling, UV mapping, texturing, PBR materials, lighting, and rendering.\nExperience with Substance 3D Painter/Designer or equivalent texturing tools.\nUnderstanding of polygon optimization, LOD, topology, and real-time rendering.\nExperience working with CAD/engineering models and industrial assets.\nKnowledge of OpenUSD/USD and NVIDIA Omniverse is highly preferred.\nFamiliarity with Unreal Engine or Unity is an advantage.\nOther Requirements\nExperience with Isaac Sim, SimReady asset specifications, or industrial digital twin platforms (Siemens, Bentley iTwin, AVEVA)\nExposure to game engines (Unreal/Unity) for cross-platform asset delivery\nBackground or coursework in mechanical/industrial design: helps bridge the gap between \"looks right\" and \"is physically correct\"\nExperience working with manufacturing, port/logistics, or heavy industrial clients","description_format":"text","description_chars":2749,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Animation","Cybersecurity","Professional
