  • Operate with an early-startup level of ownership inside a frontier-model company.
  • Wear multiple hats, set a high technical bar, and define what Applied ML at Cohere becomes.

Requirements

  • Fluency with Python and core ML/LLM frameworks.

  • Understanding of LLM architectures, tuning techniques (CPT, post-training), and evaluation methodologies.
  • Demonstrated ability to meaningfully shape LLM performance.
  • A broad view of the ML research landscape and a desire to push the state of the art.
  • Bias toward action, high ownership, and comfort with ambiguity.
  • Humility and strong collaboration instincts.
  • A deep conviction that AI should meaningfully empower people and organizations.
