Frontier Agents Intern (Fall 2026)

Job Application for Frontier Agents Intern (Fall 2026) at Together AI Back to jobs New Frontier Agents Intern (Fall 2026) San Francisco

About the Role

The Agents team investigates how to build, align, and scale frontier AI systems that can tackle complex, multi-step tasks and workflows across text and speech, with a particular focus on agentic and scientific domains. Our work sits at the intersection of agent capabilities, human-computer interaction, and infrastructure—from designing post-training methods for agentic behavior to developing evaluation frameworks for open-ended tasks where traditional metrics fall short.

As a research intern, you will work on problems at the frontier of agentic AI, where challenges in alignment, reliability, and scalability are deeply intertwined. Projects may involve developing new training recipes for self-learning and long-horizon reasoning, curating datasets for non-deterministic scientific and agentic tasks, studying failure modes in agentic behavior, or building infrastructure that enables agent operations at scale. You'll operate in a space where algorithmic innovation, dataset and interaction design, and systems work come together to push the boundaries of what AI agents can reliably accomplish.

Responsibilities

Research and implement novel techniques in one or more of our focus areas

Design and conduct rigorous experiments to validate hypotheses

Document findings in scientific publications and blog posts

Communicate the plans, progress, and results of projects to the broader team

Requirements

Currently pursuing a Masters or Ph.D. degree in Computer Science, Electrical Engineering, Information Science, or a related field

Publications at leading ML, NLP, or speech conferences or journals (such as NeurIPS, ICML, ICLR, *ACL, EMNLP, Interspeech)

Strong knowledge of Machine Learning and Deep Learning fundamentals

Experience with deep learning frameworks (PyTorch, JAX, etc.)

Understanding of how LLMs work

Strong programming skills in Python

Familiarity with Transformer architectures and recent developments in foundation models

Example Research Directions

Training, developing, and evaluating frontier models, especially in the domain of agentic tasks and workflows

Designing and curating datasets for frontier agents alignment and post-training

Studying failure modes and developing safety paradigms for agentic behavior

Research new recipes (for RL or test time scaling) for self-learning and long-context tasks completion

Building agents that act on spoken input to carry out complex, multi-step tasks

Developing ML infrastructure that can power agent operations at scale
