The role
Multi-agent AI systems are exploding, but they lack the foundational shared-state infrastructure needed to run reliably in production. Agent frameworks are proliferating, but the underlying shared-memory layer is largely unsolved. This early-stage company is building that layer: sub-80ms retrieval with ACL-gated state, designed to plug into LangGraph, CrewAI, AutoGen, and custom frameworks. This is foundational work in a category that's just getting started.
You'll be the founding engineer owning the core retrieval and state system. This isn't about integrating existing tools or working on a small feature; it's about setting the technical direction for the product, making decisions that will compound for years, and shipping the integrations that bring the first production users on. You'll define the infrastructure choices, API shape, data model, and operational posture for a critical piece of the AI stack.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
