ML Research Engineer, AI Agents - EMEA Remote

At Hugging Face, we’re on a journey to democratize good AI. We are building the fastest growing platform for AI builders with over 5 million users & 100k organizations who collectively shared over 1M models, 300k datasets & 300k apps. Our open-source libraries have more than 400k+ stars on Github.

About the Role

2025 will be the year of Agents.

LLM agents, what are these? In short, agentic systems are a way to connect an LLM to the outside world, to let it perform actions and observations. The promises of such a setup are immense : it enables an LLM to get external knowledge to ground its reasoning, use reliable tools for specific tasks, and even self-correct errors through additional iterations. An agentic system requires a powerful enough LLM to reason and plan actions. Now with the progress of LLMs in general and specifically open models overtaking closed ones, we have all the weapons to build great agents.

So Hugging Face is launching a moonshot in that direction. We’ve already published the library , gathering 4k stars in a few days at the time of writing. 

On top of keeping the momentum with smolagents, we intend to launch a new direction of effort : GUI agents, i.e. agents that take screen recordings from any GUI, and act through a mouse/keyboard setup. You may have seen such models from other companies: we’ll make them better and open, building all the stack necessary towards efficient GUI agents, and open-sourcing useful building blocks that we made along the way.

What you will do

Building agents is both exciting and challenging as it lies at the intersection of post-training, inference, orchestration as well as UX design. This job will include the whole agent stack, including:

• Maintain and improve smolagents
• Build libraries and code around agents and GUI agents
• Prepare fine-tuning datasets, training recipes, and inference orchestration.
• Leverage our large H100 cluster for large scale processing and model training.
• Release any code we built, as well as the model serving as a foundation for the community to build on, possibly as a new GUI agent framework and/or research papers.
• Collaborate and empower the community to build on top of our tools.

At Hugging Face, everything you do will have an outsized impact. Every employee is empowered to take important decisions, and every decision has a global reach thanks to our massive open-source community. This is the place on Earth where you have the best chances to make a 1000x impact.

About You

You'll enjoy working here if you are:

• Enthusiastic about agents.
• Are a generalist engineer with an ability to pick up new frameworks quickly and willing to work across the stack, from framework maintenance to model training to redacting research reports.
• Comfortable working in a fast-paced and ambiguous environment, aka shifting sands of startup land. This includes communicating with other teams to efficiently join forces, in Hugging Face’s very decentralized/anarchic organization.
• Excited to be a builder for builders! Empathy for developers across the stack and an enthusiasm for developer-first products.
• Enjoy understanding technical domains deeply and are willing to really get into the weeds.

If you're interested in joining us, but don't tick every box above, we still encourage you to apply! We're building a diverse team whose skills, experiences, and backgrounds complement one another. We're happy to consider where you might be able to make the biggest impact.

We support our employees wherever they are. While we have office spaces in NYC and Paris, we're very distributed and all remote employees have the opportunity to visit our offices. If needed, we'll also outfit your workstation to ensure you succeed. However, this job offer is quite special as it's best if you are in-person in our new Paris office. We provide relocation packages if necessary.

We want our teammates to be shareholders. All employees have company equity as part of their compensation package. If we succeed in becoming a category-defining platform in machine learning and artificial intelligence, everyone enjoys the upside.

We support the community. We believe major scientific advancements are the result of collaboration across the field. Join a community supporting the ML/AI community.
