Job Description:

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.

Job Responsibility:

  • 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

Requirements:

  • 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
What we offer:
  • An open and inclusive culture and work environment
  • Work closely with a team on the cutting edge of AI research
  • Weekly lunch stipend, in-office lunches & snacks
  • Full health and dental benefits, including a separate budget to take care of your mental health
  • 100% Parental Leave top-up for up to 6 months
  • Personal enrichment benefits towards arts and culture, fitness and well-being, quality time, and workspace improvement
  • Remote-flexible, offices in Toronto, New York, San Francisco, London and Paris, as well as a co-working stipend
  • 6 weeks of vacation (30 working days!)
