Software Engineer, GPU Kernels
Builds performance-critical GPU kernels (attention, matrix multiplication, mixture-of-experts, low-precision FP8/FP4 compute) for River AI's training and inference infrastructure. Day to day: profiling workloads, writing kernels with CUDA/Triton/CUTLASS in C++ and Python, and integrating optimizations into training and serving runtimes.
Software Engineer, Inference Systems
Builds and optimizes the model-serving runtime behind River's AI API — request scheduling, continuous batching, KV-cache management, and multi-GPU execution — to deliver fast, reliable, cost-efficient inference for large transformer models and RL sampling workloads. Core stack: Python, C++/Rust, CUDA, and frameworks like vLLM/SGLang/TensorRT-LLM.
