We’re building the shared‑memory protocol that lets AI agents learn from each other, turning isolated tools into a network of collective intelligence. Incubated by Moonsong Labs (creators of Kluster.ai, Moonbeam, Tanssi).
What you’ll do - Design and ship distributed infrastructure that captures, validates, and surfaces agent experiences in real time. - Operationalise SOTA research in LLMs, RL, and multi‑agent coordination into fault‑tolerant, low‑latency services. - Turn episodic trajectories into reusable knowledge for a growing ecosystem of mutually distrusting agents. - Set technical standards, mentor engineers, and grow the AI platform team.
Tech you’ll touch Python, Rust/Go, LangGraph / AutoGen / CrewAI, vector & graph stores, Temporal / Kafka, k8s, Terraform, modern GPU/cloud stacks. Web3, consensus, or token‑incentive know‑how is a nice‑to‑have.
You bring - A record of shipping complex AI or distributed‑systems platforms (startup or research labs welcome). - Deep appreciation of LLM post‑training, multi‑agent frameworks, and end‑to‑end MLOps. - MSc or (ideally) PhD in a STEM field; 5 + yrs hands‑on engineering. - Desire to lead and still stay close to code.
Why Entourage - Green‑field architecture, zero legacy. - Direct impact on the connective tissue of the coming agent economy. - Competitive salary, generous equity, hardware budget, London hub with quarterly off‑sites. - Inclusive culture – we hire for talent and potential, not pedigree.

Magic position for people who know HEAPs about the playwright testing framework.
We are an early stage company with a different, and we hope refreshing attitude, towards work.
We think it’s okay to not be obsessed with your job. We think if you’re a bit older (out of your 20s) you might be more of a guide for others (a Gandalf) than a power train (we hire young people for that energy who are eager to learn from you). We invest a lot in our team. We pay for you to have therapy (optional), but we want you to have it as we think you’ll be happier, calmer and “unblock” yourself. We spend half a day a week reading documentation and doing nothing else, and another full day coaching the team on cutting edge tech (how to design, build, train, deploy ai models).
We’re based in London, but open to applications from anywhere.
The main thing is that you have a well of knowledge about the open source playwright framework!

It’s a shame that we have unbelievably good hardware like collaborative robots (cobots) that could transform warehouses and yet they still struggle with basic tasks like unloading mixed pallets. Why? Because today's software can't handle real-world chaos.
That's where we come in. At ko-br, we're building the AI brains that make robots truly adaptable. Our physical AI models tackle messy, unstructured problems starting with depalletizing of mixed boxes in dynamic warehouses. Think real-time adaptation to shifting pallets, mixed SKUs, and unexpected failures.
We're a deep tech startup at the crossroads of AI, robotics, and human-machine interaction. While warehouses are our first battlefield, our core mission is physical AI. So you need to be comfortable with the idea of pivoting to other sectors like education (ex: building robots for schools and universities).
