Machine Learning Research Intern (Summer 2026)

At Scale , our Machine Learning Research team is focused on building the foundation for the next generation of AI systems-pushing the boundaries of what's possible with frontier models while ensuring safety, reliability, and alignment at every step. Our work spans across generative AI, advanced post-training methods, scalable oversight, synthetic data pipelines, red teaming, and evaluation science.

We are developing a large-scale hybrid human-machine system to power machine learning pipelines for dozens of industry-leading customers. These models and systems form the backbone of Scale's long-term strategy, enabling billions of tasks monthly and supporting some of the most complex and advanced use cases in the AI ecosystem.

You'll be working on a combination of deeply technical ML applications in production and cutting-edge research problems, with the opportunity to collaborate with leading research teams across industry and academia.

Example Projects

• Measuring the dangerous capabilities of frontier models and conducting preparedness research
• Research on the science and creation of new benchmarks for frontier models
• Research and develop new methods for training models to excel on extremely difficult reasoning problems that require long chains of thought
• Research scalable oversight protocols that enable humans to produce and quality control reasoning chains beyond their native capabilities
• Studying the boundaries of model generalization and capabilities to inform data-driven advancements.
• Research on synthetic data and hybrid data with humans in the loop to scale up high-quality data generation.
• Take models currently in production, identify areas for improvement, improve them using retraining and hyperparameter searches, then deploy without regressing on core model characteristics.
• Create post-training or agentic solutions that integrate into our ability to deliver applications for our enterprise clients
