We’re looking for a CUDA Software Developer specializing in GPU applications, algorithms, and performance optimization to accelerate Cesium’s 3D Tiling Pipelines for tiling massive 3D models and data using GPUs. Cesium’s 3D Tiling Pipelines enables our users to tile and stream their geospatial data using best-in-class tiling algorithms and optimizations for efficient runtimes. Cesium’s next generation of tiling pipelines and algorithms will harness the power of GPUs to accelerate tiling performance using a combination of migrating existing algorithms to the GPU and adopting existing CUDA libraries.

What you’ll do:

• Accelerate existing pipelines and algorithms for 3D meshes, point clouds, and other 3D content for tiling using CUDA.
• Profile and analyze currently use algorithms for hotspots that would gain from GPU acceleration.
• Develop prototypes to validate potential performance gains.
• Apply the latest hardware and software optimizations to algorithms to extract maximum performance
• Create performance model for consistent and repeatable performance analysis
• Use modern software development practices to create reusable libraries, unit tests, and documentation
• Be a key part of our development team and collaborate to accelerate the roadmap, participate in collaborative development using GitHub, code reviews, and CI

What we’re looking for:

• 8+ years of performance optimization oriented software development experience, with CUDA or similar low-level GPU acceleration being a significant part.
• You obsess over performance and extract orders of magnitude performance gains using GPUs.
• Deep understanding, creativity, and problem solving in migrating CPU algorithms to the GPU.
• Skilled at using debugging tools such as Visual Studio or Code Debugger, LLDB/GDB, and performance testing tools and profilers
• Prior experience with processing 3D data algorithms on the GPU is a plus.
• BS or MS in Computer Science or a related field
• Excellent written and verbal communication skills with a focus on user-focused impact
