About Goodfire Goodfire is an AI interpretability research lab. We build interpretability agents and infrastructure to understand, monitor, and align AI models. We believe that AI is the most consequential technology of our time. Yet AI models are trained by trial and error today, with limited understanding of what drives their behavior. Our goal is to advance the research and technology needed to fully understand and align AI so humanity can trust superintelligence. Goodfire is a public benefit corporation founded by researchers who helped pioneer the field of interpretability at OpenAI and Google DeepMind. We are headquartered in San Francisco and have raised over $200M from leading investors including Lightspeed, Menlo, and B Capital. About the role We are seeking talented, early-career researchers or engineers to execute a research project in AI interpretability. Fellows will work alongside leading interpretability researchers at Goodfire, receiving structured mentorship while contributing to important work in AI alignment. The project is expected to span 3 months, with some flexibility based on project progress and mutual agreement.
