Staff Software Engineer, 4D Engine

Architect and build the core systems behind Avala's 4D Engine — the reconstruction pipeline that fuses LiDAR, camera, radar, and IMU data into physics-grade spatiotemporal ground truth. You'll own the Gaussian Splatting renderer, temporal tracking systems, and the compute infrastructure that processes petabytes of multi-sensor data.What You'll Do:• Lead development of the 4D reconstruction pipeline (Gaussian Splatting, NeRF, multi-view stereo)• Design GPU-accelerated compute shaders for real-time point cloud processing and scene rendering• Build temporal tracking and object persistence systems across sensor frames• Architect distributed processing pipelines that scale to fleet-level data volumes• Set technical direction for the rendering team and mentor senior engineers• Collaborate with ML engineers on auto-labeling and scene understanding modelsRequirements:• 7+ years in graphics, 3D vision, or high-performance computing• Deep expertise in GPU programming (WebGPU, CUDA, Vulkan, or Metal)• Strong C++, Rust, or Dart performance optimization experience• Published work or production systems in 3D reconstruction or novel view synthesis• Experience leading technical teams of 3+ engineersNice to Have:• Experience at an AV company (Tesla, Waymo, Aurora, Cruise)• Familiarity with Gaussian Splatting, radiance fields, or differentiable rendering• WebAssembly and browser-based rendering experience
