Author, profile, and optimize CUDA kernels—GEMMs, attention, MoE routing, quantization, KV-cache, and fused epilogues—on the critical path of LLM inference.
Optimize for the hardware: exploit tensor cores and tune occupancy, memory coalescing, shared-memory/register usage, and overlap of compute with data movement.
Use kernel-authoring DSLs and compilers to prototype and ship kernels quickly without sacrificing performance.
Benchmark rigorously: build reproducible microbenchmarks and roofline analyses, and validate that kernel-level wins translate to end-to-end latency/throughput gains across model-serving stacks (vLLM, TensorRT-LLM, llm-d, SGLang).
Implement and maintain benchmarking workflows for end-to-end MLPerf Inference (and Training) runs, including workload setup, cluster configuration, runbooks, and result validation.
Lead design reviews and drive architecture within the team; decompose multi-service work into clear milestones.
Mentor junior engineers; review cross-team designs and elevate coding/testing standards.
Help ensure reproducible, well-documented benchmarking and kernel-optimization processes.
Who You Are
5+ years of experience building high-performance computing, GPU/accelerator software, or performance-critical systems.
Hands-on CUDA experience is required—you have written and optimized custom kernels and are fluent with the CUDA programming and memory model.
Deep understanding of GPU architecture and performance: tensor cores, warp/occupancy tuning, the memory hierarchy and bandwidth, NVLink/PCIe, and profiling with Nsight Compute/Systems.
Strong coding in C++ and Python; comfortable reading and writing low-level, performance-sensitive code.
Familiarity with model-serving stacks (vLLM, TensorRT-LLM, llm-d, SGLang) and the kernels that dominate their inference cost.
Strong communicator comfortable collaborating with cross-functional teams and external partners.
Bachelors in Computer Engineering or related fields.
Preferred
Triton or Mojo for authoring custom GPU kernels — highly desired.
CuTe DSL for Python-based kernel authoring on NVIDIA GPUs.
JAX and its Pallas kernel language for authoring kernels on GPU/TPU.
HIP / ROCm and AMD GPU experience.
NCCL and collective-communication performance.
Experience with alternative accelerators such as Google TPUs and Meta's MTIA.
Familiarity with kernel-authoring DSLs and nano-compilers such as KNYFE and its Block DSL.
Experience with Kubernetes at production scale.
Experience with SUNK (Slurm on Kubernetes) / Slurm for scheduling large GPU jobs.
Experience running MLPerf submissions or similar large-scale audited benchmarks.
Contributions to OSS projects such as vLLM, SGLang, PyTorch, Triton, or CUTLASS.
