Job description

We are seeking a Senior Machine Learning (ML) Research Scientist to join our team working on a novel AI safety agenda. In this role, you will design and implement innovative ML models aimed at solving advanced AI safety problems.

Key responsibilities

  • Propose, design, and implement novel ML models tailored to solve complex AI safety problems.
  • Collaborate with mathematicians and other specialized research scientists to integrate theoretical advancements into practical ML algorithms and models.
  • Adapt and fine-tune existing frontier models to enhance their applicability to specific settings.
  • Design and implement experimental protocols and evaluation frameworks to validate hypotheses and ensure robust and reproducible results, including at the scale and complexity of frontier models.
  • Analyze and interpret experimental data in order to steer future research questions and objectives.
  • Benchmark and optimize model performance and efficiency along with ML engineers to ensure the optimal usage of computing resources over the course of long experiments.
  • Communicate findings and synchronize work with other researchers and engineers.

Required skills and qualifications

  • Advanced degree in a relevant field (e.g., Computer Science, Mathematics). A PhD is preferred but not required if the candidate demonstrates exceptional abilities.
  • 5+ years of experience in deep learning research projects, in particular with frontier models.
  • Proven experience in the training, adaptation, and/or fine-tuning of frontier models across a variety of complex scenarios that involve, for example, transfer learning, domain adaptation, or meta learning.
  • Expertise in the integration and use of ML libraries such as PyTorch, TensorFlow, or JAX for the development, training, and evaluation of ML models, ideally in distributed computing environments.
  • Strong experience in Python software development, in the use of version control, collaboration tools, and experiment management and tracking tools.
  • Strong communication skills, both written and verbal, with the ability to exchange ideas with researchers across different disciplines.
  • Ability to work collaboratively in a team environment while also being self-motivated and independent.

Preferred skills and qualifications

  • Experience analyzing the behavior of frontier models in safety-critical contexts.
  • Experience in the design and development of model alignment strategies or benchmarks.
  • Experience with natural language processing or probabilistic graphical models.
  • A track record of contributing to high-quality research projects in deep learning.
