Job Description

AI Summary

• Conduct cutting-edge ML research on frontier models, including work on safety, evaluation, synthetic data generation, and advanced post-training methods for production systems serving major clients. • Required qualifications: Currently enrolled in BS/MS/PhD program in ML/NLP/CV with graduation Fall 2026 or Spring 2027, prior research publications or experience with LLMs/NLP/agents, and proficiency in Python or similar languages. • Ideal candidates have previous ML internship experience, researcher background, publications in top-tier venues (NeurIPS, ICML, ICLR), or open source contributions in areas like adversarial robustness or model alignment. • Work on diverse technical projects including measuring dangerous model capabilities, creating benchmarks, improving reasoning chains, scalable oversight protocols, and deploying improved models to production. • Summer 2026 internship (May/June start) at Scale AI with opportunity to collaborate with leading industry and academic research teams on problems directly impacting billions of monthly tasks.

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

Required to have:

Currently enrolled in a BS/MS/PhD Program with a focus on Machine Learning, Deep Learning, Natural Language Processing or Computer Vision with a graduation date in Fall 2026 or Spring 2027
Prior experience or track record of research publications on LLMs, NLP, Multimodal, agents, safety, evaluation, alignment or a related field
Experience with one or more general purpose programming languages, including: Python, Javascript, or similar
Ability to speak and write in English fluently
Be available for a Summer 2026 (May/June starts) internship

Ideally you’d have:

Have had a previous internship around Machine Learning, Deep Learning, Computer Vision, Natural Language Processing, Adversarial Robustness, Alignment, Evaluation and Agent
Experience as a researcher, including internships, full-time, or at a lab
Publications in top-tier journals such as NeurIPS, ICML, ICLR, CVPR, AAAI, etc. or contributions to open source projects
