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 are looking for talented individuals to help us develop state-of-the-art models for information retrieval as part of our Search team. This group is working on a range of tasks including generating useful dense vectors and reranking. You'll have the opportunity to revolutionise people's search experience by contributing to building an efficient and precise search system and you would have a lot of opportunity to try new things out, innovate, and productionize your ideas.

Your work will specifically focus on advancing semantic search techniques to improve accuracy and efficiency, involving working with a wide range of technologies and collaborating with other teams to integrate your work into our search infrastructure.

We're looking for someone who is passionate about search and has a strong background in information retrieval. Candidates should have experience working with a wide range of technologies and have worked collaboratively with other teams in the past.

As a Member of Technical Staff on this team, you will:

    • Design, train and improve upon cutting-edge search models.
    • Gather high-quality retrieval datasets and optimize data pipelines for model training and evaluation.
    • Work closely with model serving team to ensure that inference is fast and stable.
    • Collaborate with product teams to develop solutions.
    • Engage in research collaborations with our partner organizations and academic affiliations and publish your work in top-tier conferences and journals.
    • Join us at a pivotal moment, shape what we build, have a strong ownership mindset, and wear multiple hats!

You may be a good fit if you have:

    • Proficiency in Python and related ML frameworks such as PyTorch, Tensorflow, TF-Serving, JAX, and XLA/MLIR.
    • Experience training representation models, or using text embeddings in downstream tasks.
    • Familiarity with various information retrieval techniques, such as lexical search and dense vector search.
    • Familiarity with autoregressive sequence models, such as Transformers.
    • Strong communication and problem-solving skills.

    • Bonus points for:
    • Proficiency in other programming languages, such as C++ or Golang.
    • Experience using large-scale distributed training strategies with GPUs.

    • * This is neither an exhaustive nor necessary set of attributes. Even if none of these apply to you, but you believe you will contribute to Cohere, please reach out. We have a wide variety of backgrounds at Cohere.
If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply! If you consider yourself a thoughtful worker, a lifelong learner, and a kind and playful team member, Cohere is the place for you.
