Jacob Marks is a technical staff researcher focused on post-training safety and capabilities work at Meta's Superintelligence Lab, with nine years of experience spanning deep learning, data-centric AI, and theoretical physics. He holds a PhD in theoretical physics from Stanford and has translated that rigorous background into applied ML roles at Liquid AI and Voxel51, where he contributed notable computer vision tooling and integrations for the popular FiftyOne project. As an entrepreneur he founded and scaled a startup from idea to revenue, and his resume includes moonshot research at X (Google X) developing classical and quantum energy-based models. Jacob combines production ML engineering, research fluency, and developer evangelism—comfortable shipping evaluation tooling, model visualizations, and dataset-centric workflows. Based in San Francisco, he bridges high-risk research and pragmatic engineering, often surfacing practical improvements born from deep theoretical insight.
