About H: H exists to push the boundaries of superintelligence with agentic AI. By automating complex, multi-step tasks typically performed by humans, AI agents will help unlock full human potential.

H is hiring the world’s best AI talent, seeking those who are dedicated as much to building safely and responsibly as to advancing disruptive agentic capabilities. We promote a mindset of openness, learning and collaboration, where everyone has something to contribute.

Holistic, Humanist, Humble.

About the Team: The Agent team defines new learning algorithms and agent paradigms to push the frontiers of agentic systems. The team builds upon foundation models and reinforcement learning to develop new approaches to train artificial general agents and works closely with the LLM/VLM and Safety teams to explore new directions. In addition, the Agent team is constantly delivering agents as prototypes or MVPs to spread the agentic culture and explore new potential applications.

Key Responsibilities:

• Implement different agent logics by reusing foundation models

• Develop massive benchmark to evaluate agents capabilities and launch evaluation campaigns

• Implement state-of-the-art Deep Reinforcement learning algorithms on top of large models

• Propose research directions toward new agent paradigms and learning approaches

Requirements:

• Technical/Research skills:

  • Research expertise (PhD in ML/deep learning) in one of the following topics:

    • Reinforcement Learning

    • Agentic systems based on LLMs/VLMs

  • Proficient in Python & Git and at least one deep learning framework (PyTorch, JAX, TensorFlow)

• Soft skills

  • Enjoys collaboration and team work

  • Impactful communication

  • Eager to explore the new challenges of agentic AI

• Bonuses:

  • Experience in LLM training/fine-tuning

Location:

• H's teams are distributed throughout France, the UK, and the US

• This role has the potential to be fully remote or hybrid for candidates based in cities where we have an office - currently Paris and London

• The final decision for this will lie with the hiring manager for each individual role
