Description du poste

corporate_fare DeepMind place New York, NY, USA

• PhD and Postdoctoral research experience in Particle Physics, Plasma Physics, Nuclear Engineering, or a related field.
• 3 years of experience in research with US national laboratories or security initiatives (e.g., IAEA, NNSA, DARPA, or academic consortia).
• Experience in research or policy in radiological/nuclear security, safeguards, nonproliferation, material control, or threat reduction.
• Experience in radiation/neutron transport, reactor monitoring, detection, dosimetry, shielding defeat, and RDD/RED mechanics.

Preferred qualifications:

• Experience applying ML to radiation detection, detector calibration, or nuclear/particle event reconstruction.
• Experience in AI safety, evaluations, red-teaming, or applied AI research in lab, academic, or industry settings.
• Experience in data analysis, scientific computing (e.g., Python or C++), and simulation in neutron/radiation transport, detector response, or plume dispersion.
• Experience using AI models/agents to enhance capabilities and lower technical barriers.

Ability to design evaluations and mitigations that are demonstrably unclassified and non-export controlled by developing dual use science proxies for weapons topics. Highly collaborative, comfortable with peer review, and committed to respectful teamwork.

About the job

Google invites applications from highly qualified physicists and nuclear engineers for the position of Radiological Subject Matter Expert (SME) in the CBRNE team within the Responsible Development and Innovation (ReDI) team.

The successful applicant will be hired for a Research Scientist position serving as a technical expert evaluating and mitigating safety risks of frontier AI models (primarily but not limited to LLMs) in the radiological domain; specifically, model assistance in radiation and neutron transport modeling, radiation detector defeat and shielding optimization, reactor operations and monitoring, and radiological source managing in a demonstrably unclassified and non-export controlled manner.

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.

• Construct threat models prioritizing vulnerabilities, threat actors, and scenarios related to fission, fusion, thermonuclear weapons development, and high-energy-density dual-use regimes.

• Collaborate with engineers to design mitigations that block harmful outputs without overly degrading the model’s scientific utility. Similar to writing capability evaluations, this requires a deep understanding of dual-use science.
• Support development and refinement of Google’s nuclear safety policy. Communicate complex risks, evaluation findings, and mitigation strategies to leadership and technical/non-technical external stakeholders.
• Develop mathematical and computational frameworks to quantify capability thresholds, technical feasibility, and potential consequences of model uplift wherever possible.
