Job Description
Snapshot
Artificial Intelligence could be one of humanitys most useful inventions. At DeepMind were a team of scientists engineers machine learning experts and more working together to advance the state of the art in artificial intelligence. We use our technologies for widespread public benefit and scientific discovery and collaborate with others on critical challenges ensuring safety and ethics are the highest priority.
About Us
The current paradigm for Large Language Models (LLMs) is largely one-size-fits-all. While powerful this approach fails to capture the diverse implicit and evolving preferences of individual users. A users true intent is often revealed not in a single prompt but over the course of a long interactive conversation. The next frontier in AI is to move beyond static instruction-following and create models that dynamically learn and adapt to each user personalizing their behavior to maximize helpfulness and satisfaction over the long term.
Our team is focused on this challenge: teaching Gemini to personalize itself through interaction. We frame this problem as a multi-turn imperfect information game where the model must learn to infer a users latent goals and preferences from conversational cues. Our aim is to leverage advanced Reinforcement Learning techniques to optimize for long-horizon user satisfaction this involves tackling complex credit assignment problems in stateful interactive environments.
The techniques you develop will have a direct impact on a wide range of Gemini applications like complex multi-step tool use and agentic workflows.
Key responsibilities:
- Design and implement novel multiturn RL algorithms to train personalized LLMs. This includes exploring advanced methods for credit assignment exploration/exploitation strategies.
- Develop and scale our training infrastructure building on our existing framework for training against stateful user simulators.
- Formalize the problem of personalization by creating new metrics environments and evaluation methodologies that capture long-term user satisfaction and preference alignment.
- Collaborate closely with product teams to integrate these personalization capabilities into core Gemini products improving tasks that require sustained interaction and user understanding.
- Do cutting-edge research that pushes the boundaries of how agents learn from interactive human-in-the-loop data
To make this effort successful we need a strong RS who can help us deliver state-of-the-art personalized models. We are looking for a candidate with deep expertise in reinforcement learning and large-scale ML systems. You should be passionate about solving complex long-horizon problems and excited by the challenge of building truly adaptive and intelligent agents.
About You
In order to set you up for success as a Research Scientist at DeepMind we look for the following skills and experience:
- PhD in Machine Learning Reinforcement Learning Natural Language Processing or a related field.
- Strong data analysis and synthetic data generation skills.
- Strong development skills in Python and experience with deep learning frameworks like JAX PyTorch or TensorFlow.
- Experience building and working with large-scale ML training systems.
In addition the following would be an advantage:
- Deep theoretical and practical experience in Reinforcement Learning (e.g. policy gradient methods value-based methods model-based RL credit assignment).
- Experience developing and training large generative models (LLMs).
- Strong track record of academic publications in top-tier conferences (e.g. NeurIPS ICML ICLR AAAI).
- Familiarity with research on game theory multi-agent systems or learning from human feedback (RLHF/RLAIF).
- Experience building or using user simulators for RL training.
The US base salary range for this full-time position is between $166000 - $291000 bonus equity benefits. Your recruiter can share more about the specific salary range for your targeted location during the hiring process.
