Senior AI Inference Systems Engineer

StackYak is building the infrastructure layer for AI in San Francisco. This is an early-stage founding role where you will shape the systems layer beneath the product, with broad autonomy and rapid execution. You will own how models run, choosing precision, quantization, and memory strategies, and selecting serving runtimes. You will benchmark, deploy, and operate real inference systems at scale, influencing architecture and automation across multiple GPUs and nodes.
