Department: Immersive Technologies
Experience: 4–6 Years
To own the in-engine look development of immersive surgical training modules by assembling 3D assets, configuring materials, lighting, environments, post-processing, cameras, and training UI within Unity. The role will ensure that art assets are correctly integrated, visually consistent, performance-optimized, and delivered as development-ready Unity scenes for implementation by Unity developers and simulation engineers.
Build, configure, and maintain Unity scenes for immersive surgical training modules.
• Assemble 3D environments, surgical instruments, robotic components, anatomical assets, and supporting elements into production-ready scenes.
• Establish reusable Unity scene templates and master configurations for different training modules.
• Design and implement realistic lighting setups for operating-room and surgical training environments.
• Create and maintain master lighting rigs suitable for different training scenarios.
• Configure real-time and baked lighting workflows based on project requirements.
• Optimize lighting quality while maintaining target workstation GPU performance.
• Evaluate scenes under different camera positions, viewpoints, and training conditions.
• Ensure adequate visual clarity for surgical instruments, anatomy, UI elements, and critical training information.
Materials & Rendering Setup
• Import and configure materials and textures produced by 3D Texturing and Look-Dev teams.
• Configure material properties to achieve the required visual quality and physical appearance.
• Identify and resolve material, shader, texture, and rendering issues during asset integration.
• Support the development and maintenance of standardized material and rendering workflows.
Asset Integration & Art-to-Engine Pipeline
• Import and configure models, textures, animations, prefabs, and other art assets within Unity.
• Identify and correct common integration issues related to scale, orientation, pivots, transforms, hierarchy, materials, and asset settings.
• Ensure assets comply with established art-to-engine standards before integration into training modules.
• Coordinate with 3D Modeling, Sculpting, Texturing, and Technical Art teams to resolve asset-related issues.
Training UI & HUD Implementation
• Design and implement training-oriented UI layouts within Unity.
• Training HUDs
Ensure UI is visually consistent with the overall simulator experience.




• Ensure instructional UI remains readable and accessible at relevant training distances and screen resolutions.
• Work with UX/UI designers and Unity developers to implement approved UI designs.
• Scene Performance & GPU Optimization
• Profile Unity scenes to identify GPU and rendering performance bottlenecks.
• Optimize lighting, materials, textures, shaders, post-processing, draw calls, and scene complexity.
• Collaborate with Technical Artists, Unity Developers, and Simulation Engineers to resolve performance issues.
• Balance visual fidelity with real-time performance requirements without compromising critical training elements.
Ensure post-processing supports visual clarity and realism without negatively affecting performance.
• Maintain consistent visual treatment across different training modules.
Technical Artists
~3D Modelers
~ UI/UX Designers
~ Clinical SMEs
~ • Participate in art pipeline reviews, scene reviews, and development planning meetings.
~ • Communicate technical dependencies, integration issues, and performance concerns proactively.
~ • Incorporate artistic, technical, clinical, and usability feedback into scene development.

Dev-Ready Scene Quality & Handoff
• Establish and enforce an art-to-engine handoff checklist for every training module.
• Conduct quality checks before scenes are handed over to Unity developers for module implementation.
• Asset scale and orientation
Performance
Asset dependencies
• Sign off scenes as development-ready once defined quality and performance requirements are met.
• Maintain quality standards without unnecessarily delaying development delivery.
Maintain Unity scenes, prefabs, materials, UI assets, and related files using Git/Git LFS or the approved version-control workflow.
• Follow project naming conventions, folder structures, scene organization, and asset management standards.
• Document scene configurations, lighting setups, performance considerations, and known dependencies where required.
• Ensure changes are traceable and maintainable throughout the project lifecycle.
Explore new Unity rendering, lighting, shader, UI,



and look-development techniques.
• Contribute to improving the visual quality and performance of the surgical training simulator.
• Stay updated with developments in Unity, real-time rendering, technical art, XR/VR/AR, serious games, and simulation.
• Qualifications and Experience:
• Diploma / Bachelor’s degree / equivalent qualification in Game Art, 3D Design, Animation, Computer Graphics, Multimedia, Visual Effects, or a related field.
• 4–6 years of professional experience in Unity Look Development, Technical Art, Environment Art, or real-time 3D production .
• Strong professional experience working with Unity.
• Deep experience in at least one Unity rendering pipeline: Strong understanding of real-time lighting, materials, rendering, scene management, and optimization.
• Experience implementing UI within Unity.
• Experience with prefab, scene, hierarchy, and asset management workflows.
• Experience working within a multi-disciplinary art and engineering pipeline.
• Experience in surgical simulation, medical visualization, reliable games, gaming, XR/VR/AR, or digital-twin projects will be an added advantage.
Strong proficiency in Unity and real-time 3D workflows.
