You will operate across the full research-and-engineering lifecycle of frontier reasoning and agentic systems. Bridge research to production: Tackle unsolved problems in agentic reasoning, turning early exploratory prototypes into hardened production features for Gemini releases.
Build and scale systems: Architect and optimize distributed post-training pipelines and agent-environment simulation loops across thousands of accelerators.
Run scientific ablations: Design rigorous experiments and failure analyses to isolate performance bottlenecks and communicate findings through clear write-ups.
Drive technical excellence: Maintain high code quality and architectural health across shared Reinforcement Learning and modeling codebases.
Minimum qualifications:
Bachelor's or Master's degree in Computer Science, Mathematics, Physics, a related quantitative field, or equivalent practical experience.4 years of experience building, scaling, and debugging machine learning models using deep learning frameworks (e.g., JAX, PyTorch, or TensorFlow).Experience in at least one core area: Reinforcement Learning (RL), Post-Training (SFT/RLHF/RLAIF), Agentic Tool-Use, or Inference-Time Search.
Preferred qualifications:
PhD in Computer Science, Machine Learning, Physics, or a related quantitative field.
Experience designing asynchronous agent-environment simulation loops or large distributed post-training pipelines.
Experience prototyping new hypotheses quickly while keeping shared codebases clean, robust, and production-grade.
At Google DeepMind, the PRISM (Planning, Reasoning, Inference & Structured Models) team brings together researchers and engineers to advance the frontiers of AI reasoning and autonomous agentic systems.
Do not wait to apply after reading this description a high application volume is expected for this opportunity.
We reject the false tradeoff between research and execution, pursuing breakthroughs on open AI challenges while embedding directly into core teams to land those capabilities in production. Our work powers Gemini & Gemma—developing core reasoning, multi-agent capabilities, RL and inference scaling in Gemini, and spearheading Gemma 270M.
We deliver critical contributions to AI Grand Challenges (such as our gold medal-winning IMO 2025 effort), drive product innovations like 'Deep Think' mode and agentic inference scaling in antigravity, and contribute to Alphabet-wide initiatives including AI for Science and Project Big Sleep. You will operate across the full research-and-engineering lifecycle, developing distributed post-training infrastructure and algorithms that enable Gemini models to solve complex, multi-step problems autonomously. Artificial intelligence will be one of humanity's most transformative inventions.
At Google DeepMind, we are a pioneering AI lab with exceptional interdisciplinary teams focused on advancing AI development to solve complex global challenges and accelerate high-quality product innovation for billions of users.
We use our technologies for widespread public benefit and scientific discovery, ensuring safety and ethics are always our highest priority. We are pushing the boundaries across multiple domains.
Our global teams offer diverse learning opportunities and varied career pathways for those driven to achieve exceptional results through collective effort. Individual pay is determined by factors including job-related skills, experience, and relevant education or training.
