You will work on the GPU performance layer powering large-scale, high-throughput AI systems used by Fortune 500 customers. This role is ideal for someone who deeply understands NVIDIA GPU architecture, memory hierarchy, warp-level execution, and profiling workflowsnot someone coming from generic hardware, FPGA, or non-NVIDIA compute backgrounds. You will directly influence the GPU efficiency, throughput, and scalability of mission-critical AI systems. What Youll Do - Design, implement, and optimize custom CUDA kernels for NVIDIA GPUs, with a focus on maximizing occupancy, memory throughput, and warp efficiency. - Profile GPU workloads using tools such as Nsight Compute, Nsight Systems, nvprof, and CUDA‐MEMCHECK. - Analyze and eliminate performance bottlenecks including warp divergence, uncoalesced memory access, register pressure, and PCIe transfer overhead. - Improve GPU memory pipelines (global, shared, L2, texture memory) and ensure proper memory coalescing. - Collaborate closely with AI systems, model acceleration, and backend distributed systems teams. - Contribute to GPU architecture decisions, kernel libraries, and internal performance-engineering best practices. What Were Looking For - Proven track record building NVIDIA CUDA kernels from scratchnot just calling existing libraries. - Strong ability to optimize kernels (tiling strategies, occupancy tuning, shared memory design, warp scheduling). - Deep understanding of CUDA threads, warps, blocks, and grids, GPU memory hierarchy and memory coalescing, as well as warp divergence (how to detect, analyze, and mitigate it) - Experience diagnosing PCIe bottlenecks and optimizing host-device transfers (pinned memory, streams, batching, overlap). - Familiarity with C++, CUDA runtime APIs, and GPU debugging/profiling tooling. Bonus Points - Experience with multi-GPU or distributed GPU systems (NCCL, NVLink, MIG). - Background in GPU acceleration for ML frameworks or HPC workloads. - Knowledge of model inference optimization (TensorRT, CUDA Graphs, CUTLASS). - Exposure to compiler-level optimization or PTX/SASS analysis. - Startup experience or comfort working in fast-moving, ambiguous environments. Why This Role Will Pivot Your Career - Research pedigree: MIT CSAIL founders recognized for breakthrough AI and systems contributions. - Customer impact: Deploy AI solutions powering Fortune 500 clients. - Industry momentum: Lab alumni have led high-value acquisitions (MosaicML Databricks, Run:AI Nvidia, W&B CoreWeave). - Funding & growth: Oversubscribed seed round, next funding in 2026. - Career growth & influence: Lead AI initiatives, optimize pipelines, and directly impact production AI systems at scale. - Culture & autonomy: Own critical systems while collaborating with world-class engineers. - Aspirational impact: Solve GPU/AI performance challenges few engineers ever face.
