About the role

Research Scientist/Engineer role at Google DeepMind focused on autonomous security, designing post-training methodologies, scalable evaluation environments, and autonomous agent systems to advance AI security capabilities and integrate findings into Google products and defenses.

Responsibilities

  • Design and iterate on post-training methodologies for Gemini, including reinforcement learning from execution feedback, multi-step trajectory reward modeling, and supervised fine-tuning on curated security datasets.
  • Build scalable simulated environments and synthetic data pipelines to execute complex security workflows and generate high-signal training trajectories at scale.
  • Architect autonomous agent harnesses capable of multi-step planning, tool orchestration, and decision-making under adversarial conditions.
  • Develop end-to-end evaluation benchmarks that measure frontier capability limits and trajectory fidelity across realistic offensive, defensive, and vulnerability tasks.
  • Transition research innovations into Google's internal defenses and customer products, while contributing to technical reports and ML and security publications.

Qualifications

  • PhD in Computer Science, Cybersecurity, ML, a related field, or equivalent practical experience.
  • 4 years of experience in Python and ML frameworks (PyTorch, JAX, or TensorFlow) training, fine-tuning, and evaluating foundation models.
  • 3 years of experience applying ML or automated reasoning to cybersecurity, systems, program analysis, or code generation.
  • 2 years of experience in LLM post-training, including supervised fine-tuning, execution-feedback reinforcement learning, and multi-step trajectory reward modeling.
