About the job

Cohere is seeking a Member of Technical Staff, Applied ML to work directly with enterprise customers on challenging problems that push the limits of Large Language Models (LLMs). In this role, you will gain a deep understanding of customer domains, design custom LLM solutions, and deliver production-ready models to solve high-value business problems. You will not just use APIs, but will train and customize frontier models using Cohere's full stack, including CPT, post-training, retrieval and agent integrations, model evaluations, and state-of-the-art modeling techniques. Your work will directly influence the capabilities of Cohere's foundation models, shaping their next generation. This role offers a unique opportunity to combine the breadth of an early-stage CTO with the infrastructure and scale of a deep-learning lab, requiring you to wear multiple hats, set a high technical bar, and define the future of Applied ML at Cohere.

Responsibilities

  • Contribute to the design and delivery of custom LLM solutions for enterprise customers.
  • Translate ambiguous business problems into well-framed ML problems with clear success criteria and evaluation methodologies.

  • Develop state-of-the-art modeling techniques that directly enhance model performance for customer use-cases.
  • Contribute improvements back to the foundation-model stack, including new capabilities, tuning strategies, and evaluation frameworks.
  • Work as part of Cohere’s customer-facing MLE team to identify high-value opportunities where LLMs can unlock transformative impact for enterprise customers.

Requirements

  • Strong ML fundamentals and the ability to frame complex, ambiguous problems as ML solutions.
  • Fluency with Python and core ML/LLM frameworks.
  • Experience working with large-scale datasets and distributed training or inference pipelines.
  • 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.

Benefits

  • A weekly lunch stipend of $75/£75 or equivalent in your local currency for lunch.
  • Full health and dental benefits, including a separate budget for mental health.
  • RRSP matching, 401K, Pension Scheme.
  • 100% Parental Leave top-up for up to 6 months, for either parent.

  • Education & learning stipend for conferences, courses, and coaching.
  • 6 weeks of paid vacation (30 working days!).
  • Budget for traveling to other offices if you are remote, plus an annual company offsite.
  • A co-working benefit for those not near an office.
