About the role
- We are seeking a highly skilled GPU Kernel Engineer who is passionate about pushing the limits of performance on modern accelerators.
- You will work across the hardware-software stack, from low-level kernel development to integrating optimized ops into high-level ML frameworks used for large-scale training and inference.
- This role is ideal for someone who thrives at the intersection of GPU programming, systems engineering, and cutting-edge AI workloads, and who wants to make meaningful contributions to the efficiency and scalability of our ML platform.
Responsibilities
- Design, implement, and optimize custom GPU kernels using C++, PTX, CUDA, ROCm, Triton, and/or JAX Pallas.
- Profile and optimize end-to-end performance of ML operations, with a focus on large-scale LLM training and inference.
- Develop performance models, identify bottlenecks, and deliver kernel-level improvements that significantly accelerate AI workloads.
- Collaborate with ML researchers, distributed systems engineers, and model-serving teams to optimize compute performance across the stack.
Requirements
- Bachelor's, Master's, or PhD in Computer Science, Computer Engineering, Electrical Engineering, Applied Mathematics, or a related field.
- Hands-on experience with Triton and/or JAX Pallas for custom kernel development.
- Strong understanding of PTX, GPU ASM, and low-level GPU execution.
- Experience with AMD GPUs and ROCm optimization.
- Experience with efficient model serving frameworks (e.g., vLLM, TensorRT).
- Experience with TPUs, XLA, or similar accelerator programming environments.
