More:

We are an early-stage AI infrastructure company building a persistent, high-speed knowledge layer for agentic AI, enabling thousands of AI agents to query a shared knowledge base concurrently. We are spinning out of a leading UK university and are currently hardware-led while building out our software capability from scratch. This is an Edinburgh-based hybrid role, with UK-wide candidates also considered, and you will work closely with our CTO on the software-side modelling and benchmarking that proves the system works.
