Researcher, Pretraining Safety

Responsibilities

• Develop new techniques to predict, measure, and evaluate unsafe behavior in early-stage models
• Design data curation strategies that improve pretraining priors and reduce downstream risk
• Explore safe-by-design architectures and training configurations that improve controllability
• Introduce novel safety-oriented loss functions, metrics, and evals into the pretraining stack
• Work closely with cross-functional safety teams to unify pre- and post-training risk reduction

Requirements

• Experience developing or scaling pretraining architectures (LLMs, diffusion models, multimodal models, etc.)
• Proficiency with training infrastructure, data pipelines, and evaluation frameworks (Python, PyTorch/JAX, Apache Beam)
• Experience in hands-on research, including designing, implementing, and iterating on experiments
• Strong statistical reasoning and rigor in experimental design
• Ability to build clean, scalable research workflows
