Summary:

UST is looking for Senior UX Designer

The Opportunity:

We are looking for a Senior Technical Artist / Level Designer with strong expertise in Unity3D, AR/VR environment development, Physically Based Rendering (PBR), shaders, lighting, and real-time optimization.

The candidate will design, assemble, and optimize immersive AR/VR environments while maintaining high visual quality and stable performance across standalone and PC-based XR platforms. This role requires a balance of creative environment design and hands-on technical expertise.

Key Responsibilities

Level and Environment Design

• Design and build immersive AR/VR environments in Unity3D.

• Create effective spatial layouts, navigation paths, interaction zones, and user journeys.

• Develop level blockouts and convert them into production-ready environments.

• Ensure appropriate scale, proportions, visibility, accessibility, and user comfort.

• Organize Unity scenes, prefabs, assets, lighting, and interactive elements efficiently.

• Work with UX designers and developers to implement intuitive spatial interactions.

• Iterate on environments based on user testing, performance results, and stakeholder feedback.

PBR Materials and Texturing

• Create, configure, and optimize PBR materials for real-time AR/VR applications.

• Work with albedo or base color, normal, metallic, roughness or smoothness, ambient occlusion, height, and emission maps.

• Ensure physically accurate material response under different lighting conditions.

• Maintain consistent texel density, texture resolution, and material quality across environments.

• Create reusable materials, material instances, trim sheets, texture atlases, and modular asset libraries.

• Review imported 3D assets for correct UVs, normals, tangents, texture maps, and material configuration.

• Troubleshoot PBR issues such as incorrect reflections, excessive smoothness, visible seams, normal-map problems, and inconsistent lighting.

• Optimize texture formats, compression settings, mipmaps, and texture memory for XR devices.

Shaders and Rendering

• Create and modify shaders using Unity Shader Graph.

• Develop and optimize shaders for surfaces, transparency, reflections, effects, and environment interactions.

• Work with Unity URP as the primary rendering pipeline.

• Understand the use cases and limitations of Built-in Render Pipeline, URP, and HDRP.

• Minimize shader complexity, variants, keywords, texture samples, and expensive rendering operations.

• Configure materials and shaders for mobile GPUs and standalone VR headsets.

• Support custom shader implementation using HLSL when required.

• Diagnose visual and performance issues using Unity Frame Debugger and GPU profiling tools.

Lighting and Visual Quality

• Design and configure lighting for immersive AR/VR environments.

• Work with baked, mixed, and real-time lighting based on platform requirements.

• Configure lightmaps, reflection probes, light probes, shadows, and post-processing.

• Ensure PBR materials respond consistently to environmental lighting.

• Balance visual fidelity with GPU, memory, thermal, and frame-rate constraints.

• Reduce lighting artifacts, light leaks, shadow issues, and inconsistent reflections.

• Maintain visual consistency across AR, standalone VR, and PC-VR platforms.

Performance Optimization

• Profile Unity scenes using Unity Profiler, Memory Profiler, Frame Debugger, and platform-specific tools.

• Optimize draw calls, SetPass calls, batches, triangles, vertices, shader complexity, overdraw, and texture memory.

• Implement LOD Groups, occlusion culling, static batching, GPU instancing, and mesh optimization.

• Optimize transparent materials, particle effects, reflections, shadows, and post-processing.

• Reduce unnecessary material variations and shader variants.

• Establish performance budgets for models, textures, materials, lighting, and effects.

• Maintain target frame rates required for comfortable AR/VR experiences.

• Identify whether performance bottlenecks are CPU-bound, GPU-bound, memory-related, or asset-related.

Cross-Functional Collaboration

• Work closely with 3D Artists, Technical Artists, UX Designers, and Unity Developers.

• Define asset creation and Unity import standards.

• Review environments for visual quality, technical correctness, and performance.

• Provide guidance on PBR workflows, shaders, lighting, and XR optimization.

• Document scene-building standards, performance budgets, material guidelines, and optimization practices.

Required Qualifications

• 6+ years of experience in Technical Art, Level Design, Environment Design, or real-time 3D production.

• Strong hands-on experience with Unity3D.

• Experience designing and delivering AR/VR environments.

• Strong knowledge of PBR materials and physically based shading principles.

• Experience with Unity Shader Graph, materials, lighting, and post-processing.

• Strong understanding of Unity URP.

• Experience with spatial design, scene composition, scale, navigation, and user flow.

• Experience profiling and optimizing applications using:

o Unity Profiler

o Unity Memory Profiler

o Unity Frame Debugger

o RenderDoc or equivalent GPU profiling tools

• Understanding of UV mapping, texel density, normal maps, texture atlases, mipmaps, and texture compression.

• Experience optimizing content for standalone VR or mobile XR devices.

• Working knowledge of Blender, Maya, 3ds Max, Substance 3D Painter, or similar tools.

• Basic C# knowledge for Unity implementation and editor workflows.

Preferred Qualifications

• Experience with Meta Quest, HoloLens, Apple Vision Pro, Pico, HTC Vive, or PC-VR platforms.

• Experience with OpenXR, XR Interaction Toolkit, and AR Foundation.

• Knowledge of HLSL and custom shader development.

• Experience with Unreal Engine materials and environment workflows.

• Experience with digital twins, enterprise visualization, training, simulation, or industrial AR/VR applications.

• Knowledge of modular environment design and procedural content workflows.

• Experience with Substance 3D Designer and Substance 3D Painter.
