Software Engineer, Inference Systems

We are looking for exceptional inference systems engineers to build the engines that serve large models through the River API. Your goal is to deliver fast, reliable inference while making efficient use of GPU compute and memory.

You will take ownership of the serving runtime, from request scheduling and continuous batching to KV-cache management, distributed model execution, and checkpoint loading. Your work will support both customer-facing inference and the sampling workloads that power reinforcement learning.
