Job Title: 3D Modeler Artist – Immersive Surgical Training

Department: Immersive Technologies.

Location: Vapi, Gujarat – On-site

Reports To: XR Lead

Job Purpose:

To create high-quality, production-ready 3D assets for an immersive surgical training and robotic simulation platform, including surgical instruments, robotic console components, operating-room environments, medical equipment, and anatomical models. The role will support the end-to-end 3D asset pipeline by developing optimized models from references, CAD data, technical drawings, and clinical inputs for integration into real-time simulation environments.

Key Responsibilities:

1. 3D Modeling & Asset Development

- Create high-quality 3D models of surgical instruments, medical devices, robotic console components, operating-room environments, and supporting assets.
- Develop both hard-surface and organic models based on photographs, technical references, CAD data, drawings, and clinical inputs.
- Ensure models accurately represent real-world dimensions, proportions, geometry, and functional characteristics.
- Maintain clean topology, proper edge flow, object hierarchy, naming conventions, and real-world scale.

2. Real-Time & Simulation-Ready Asset Preparation

- Create optimized 3D assets suitable for real-time rendering and interactive surgical simulation.
- Develop LOD-ready models where required and maintain appropriate polygon budgets for real-time performance.
- Ensure correct pivots, transforms, orientation, scale, and hierarchy for downstream integration.
- Optimize meshes while maintaining the required visual quality and geometric accuracy.
- Prepare assets for integration into Unity and other real-time simulation environments.

3. Surgical & Medical Asset Development

- Develop realistic 3D representations of surgical instruments, robotic systems, medical equipment, operating-room environments, and anatomical structures.
- Work with clinical and medical experts to understand surgical workflows, instrument usage, and anatomical requirements.
- Incorporate clinical and technical feedback into 3D asset development.
- Ensure appropriate visual and dimensional accuracy for surgical training and simulation applications.

4. CAD, Reference & Mesh Preparation

- Convert and optimize CAD/reference data for use in real-time 3D environments.
- Perform basic CAD cleanup, mesh optimization, retopology, and geometry preparation.




- Prepare clean meshes for handover to sculpting, texturing, rigging, animation, and technical-art teams.
- Perform basic UV layout and ensure assets are appropriately structured for downstream texturing.

5. Cross-Functional Collaboration

- Work closely with 3D Artists, Technical Artists, Unity Developers, Simulation Engineers, Clinical Experts, and XR teams.
- Participate in regular production and pipeline review meetings.
- Coordinate with downstream artists for sculpting, texturing, rigging, and animation requirements.
- Proactively communicate technical challenges, dependencies, quality issues, and production blockers.
- Contribute to improving the overall 3D production pipeline and asset development standards.

6. Documentation, Version Control & Quality

- Follow established asset naming, folder structure, modeling, and production standards.
- Maintain asset versions using Git, Git LFS, or the approved Digital Asset Management (DAM) workflow.
- Document polygon budgets, LOD structure, asset versions, references, and known issues where required.
- Perform quality checks on geometry, topology, scale, pivots, naming, and performance before asset handover.
- Ensure timely delivery of assets according to project milestones and production requirements.

7. Innovation & Learning

- Contribute to the development of next-generation immersive surgical training and robotic simulation technologies.
- Explore new techniques for 3D modeling, optimization, visualization, and real-time simulation.
- Stay updated with emerging technologies in 3D modeling, XR/VR/AR, medical visualization, gaming, and simulation.
- Contribute to process improvements and innovative approaches for creating realistic medical and surgical assets.

Qualifications and Experience:

- Diploma / B.E. / B.Tech / Bachelor’s degree / equivalent qualification in 3D Design, Animation, Game Art, Multimedia, Visual Effects, or a related field.
- 4–6 years of professional experience in 3D modeling and asset development.




- Robust professional experience with Autodesk Maya and/or Blender.
- Experience in game-ready, simulation-ready, or real-time 3D asset production.
- Experience with hard-surface and/or organic modeling.
- Experience creating 3D assets from references, photographs, technical drawings, or CAD data.
- Experience working within a multi-artist or production pipeline is preferred.
- Experience in medical visualization, surgical simulation, gaming, XR/VR/AR, automotive visualization, or digital-twin projects will be an added advantage.

Skills and Competencies:

- Strong proficiency in Maya and/or Blender.
- Strong understanding of hard-surface and organic 3D modeling.
- Good understanding of topology, retopology, UVs, polygon optimization, and LODs.
- Understanding of real-time asset preparation and Unity workflows.
- Basic knowledge of Git / Git LFS or equivalent version-control workflows.
- Strong attention to detail and visual accuracy.
- Ability to interpret technical drawings, CAD data, and real-world references.
- Good understanding of scale, pivots, transforms, hierarchy, and asset organization.
- Strong communication and collaboration skills.
- Ability to work in a multidisciplinary environment involving artists, engineers, clinicians, and technical teams.
- Passion for 3D visualization, simulation, immersive technologies, and medical technology.

Key Performance Indicators (KPIs):

- Quality, accuracy, and visual fidelity of 3D assets developed.
- Timely completion of assigned modeling and asset-development activities.
- Compliance with topology, polygon, scale, pivot, naming, and LOD standards.
- First-pass acceptance rate of submitted assets.
- Quality and efficiency of CAD/reference-to-production asset conversion.
- Successful handover of clean assets to sculpting, texturing, technical-art, and Unity teams.
- Compliance with real-time performance and optimization requirements.
