Entourage | REMOTE | Principal AI Engineer – Collective‑Memory / Multi‑Agent Systems | Full‑time + meaningful equity

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.

Ploid AI | Barcelona, Spain | HYBRID (preferably on-site) | Founding Engineers | Full-time + Equity

We’re building an AI-first bioinformatics platform to empower plant breeders and life science researchers with agentic AI and LLMs. Backed by pre-seed funding and real demand from biotech and seed companies, we’re looking for versatile founding engineers to help us shape the future of AI in genomics.

What you’ll do:

• Architect and build AI workflows, agentic interfaces, and data pipelines

• Work across the stack: Go, Python, TypeScript

• Contribute to system design, infrastructure (AWS, Docker, Terraform), and devops

• Collaborate closely with scientists and iterate from prototype to product

• Help define our technical culture and roadmap as a core founding member

Nice-to-haves (not all required): LLM integration, RAG systems, gRPC, scientific computing, cloud/on-prem hybrid systems

About us: We’re an early team of engineers and scientists with strong academic and industry backgrounds (ex-BCG, PhD in Plant Biotech, M.Sc. AI). We’re committed to building something impactful, technical, and genuinely useful for life science.

∇ Full-stack Rust (Leptos & Axum)

∇ Based in Busan & Seoul

∇ Building a production finance model for open source: https://prizeforge.com

∇ Prototype works and tech is accelerating

You need to be prepared for the not-fun work of founding. Prototypes lurk in every corner. We know what engineering should look like and we do not complain when we are not looking at it. We just build. Founding can be extremely rewarding and I need to build out a team and put some equity into hands that will take care of it. Our mission is extremely important. We are making progress and will be growing. People with enough vision to commit to this train will be taken care of.

I am all for ample vacations and flexible hours. This company has the right shape to offer those things in the future. Right now, it's about grit and who wants a shot at doing something risky with a lot of payoff. If the market isn't going to give you the career advancement, high-risk opportunities, or compensation you want, you are welcome to try to make this your ticket as well as mine.

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!

Oxidian | https://www.oxidian.com | Remote (Ireland/EU ONLY)

We make sure public money is well invested by building software for governments. We're doing to government software services what challenger banks did to banking.

Our clients are mainly governmental research institutions - we're building tools for scientists to process & visualise data, HPC data processing libraries, web apps to make people's working lives easier, and DevOps pipelines.

Currently hiring a senior python dev, a mid-level python dev, and a senior rust/c++ dev.

We do government work so the location requirement is strict. Save yourself some time and don't apply if you're outside the EU.
