Key Responsibilities: Gaussian Splatting & Real-Time Rendering Develop and optimize Dynamic Gaussian Splatting (3DGS) rendering pipelines. Improve splat rendering performance through sorting, data layout, and shader optimization. Troubleshoot rendering issues such as flickering, popping, sorting inconsistencies, and CPU/GPU precision differences. Support real-time rendering pipelines for avatar and XR applications. GPU & Mobile Optimization Optimize rendering pipelines for mobile GPUs, particularly Qualcomm Adreno .Optimize performance under mobile constraints such as limited memory, bandwidth, power, and thermal budgets. Tune rendering performance for Android phones and AR glasses. Analyze GPU bottlenecks, frame timing, memory bandwidth, synchronization, and CPU/GPU overlap. Shader & GPU Programming Develop and optimize graphics and compute shaders usingGLSL/HLSL, SPIR-V, and Vulkan .Work with GPU compute techniques such as sorting, culling, binning, blending, prefix sums, and parallel processing. Optimize shader input/data pathways for efficient on-device execution. Integrate rendering pipelines with motion and lighting systems. Data Pipeline & Memory Optimization Design compact and memory-efficient representations for Gaussian Splatting frame data. Optimize CPU-to-GPU data transfers. Reduce intermediate processing and runtime memory overhead. Apply efficient memory-management techniques for real-time embedded systems. Debugging & Validation Debug complex graphics and rendering issues on physical devices. Investigate numerical precision issues and CPU/GPU inconsistencies. Use graphics profiling and debugging tools to identify performance bottlenecks. Validate rendering output against reference implementations. Support pre- and post-silicon testing across simulation, emulation, and on-device environments. Collaboration Collaborate with XR, computer vision, graphics, and avatar teams. Contribute to on-device demos and prototypes for phones and AR glasses. Work with internal teams and stakeholders to implement new graphics features. Prepare technical design documentation and feature specifications.
