We're a small senior team building the runtime, agents, and platform that power production AI at our customers. The bar is high, the scope is real, and the work ships.

Build the high-performance services and runtimes behind production AI agents - low-latency inference paths, data pipelines, and the platform glue that everything sits on.
Work alongside senior AI engineers on real production agents - from evals and prompt engineering through model integration and the messy bits of shipping AI into live workflows.
Design the product surfaces that operators actually use - dashboards, agent control planes, and the small interactions that make AI feel trustworthy day to day.
Own the analytics behind CosX's marketing motion - from content performance to pipeline attribution - and turn data into clear recommendations the team can act on.
