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.
