San Francisco · Applied AI entertainment
Build systems creators can actually direct.
janitor is hiring engineers to turn AI characters from loose autocomplete into durable, controllable worlds: search, memory, orchestration, realtime infrastructure, and interactive clients that hold up under millions of users.
01
Creator control over model vibes.
We care about plot beats, persistent characters, moderation, tools, and memory.
02
Hard product surface, not demo ware.
Latency, ranking quality, GPU cost, queues, storage, and clients all matter.
03
Small team, high ownership.
You will ship core systems, operate them, and watch real users stress them immediately.
