Who are we?

Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises who are building AI systems to power magical experiences like content generation, semantic search, RAG, and agents. We believe that our work is instrumental to the widespread adoption of AI.

We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. We like to work hard and move fast to do what’s best for our customers.

Cohere is a team of researchers, engineers, designers, and more, who are passionate about their craft. Each person is one of the best in the world at what they do. We believe that a diverse range of perspectives is a requirement for building great products.

Join us on our mission and shape the future!

Why this role?

We’re looking for an experienced machine learning researcher / engineer who can help us push the frontiers of agentic LLM systems. As a part of the team, you will help drive exploration and development of agentic techniques and have the opportunity to build the models that power our agentic solutions. Agentic LLM systems are being deployed widely across enterprise companies including through Cohere’s North platform. In this role, you’ll be working with a team developing new strategies for training models for advanced agent capabilities including reasoning, tool use, and memory. This includes developing data-generation techniques for post-training (SFT and RL) Cohere’s models. Model advancements have direct impacts on North and other Cohere products creating an exciting opportunity where core model development leads to direct product advancements.

Please Note: We have offices in London, Toronto, San Francisco, and New York, but we also embrace being remote-friendly! Our preference for this role is that you are based in Eastern Time, New York office, remote or hybrid works!

As a Member of Technical Staff for Agents Modeling you will:

• Design and develop novel agentic solutions

• Improve upon SOTA on hard agentic tasks

• Research the next-generation of on-line learning-from-experience self-improvement

• Work with partner teams (Reasoning, Post-training, Pre-training, etc.) to improve performance of agentic system

• Work with an amazing team of researchers and engineers pushing the boundaries

You may be a good fit if you have:

• Have a PhD in computer science or related field or similar industry research experience

• Strong software engineering skills

• Proficiency in Python and experience with ML-related code (e.g., pytorch, numpy, etc.)

• Experience with LLMs and agentic frameworks

• Experience with post-training LLMs (SFT, PEFT, or RL)

• Experience with building synthetic data generation pipelines

If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply!

We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities.
