Edra Labs | Full-Time | Equity | New York & London (No remote) | AI Engineers / Full-Stack Engineers

At Edra we built a new, proprietary method of learning that allows LLMs to understand and automate business processes.

Founded by Eugen and Yannis, former co-heads of Forward Deployed AI Engineering at Palantir.

We named the company Edra for “the seat of the teacher”.

Edra AI is a novel learning system, deployed with several customers and are looking to scale up. Backed by top-tier investors from the Palantir ecosystem with offices in New York and London.
