Who are we?
We’re a team of engineers, thinkers, and champions whose aim is to give technology language. Every day our team is breaking new ground, as we build transformational AI technology and products for enterprise and developers that wish to harness the power of Large Language Models.

We're driven by ambition, as we firmly believe that our technology has the potential to revolutionise the way industries engage with natural language. Our strong technical foundation speaks for itself, with our team composed of world-class experts who have collectively accumulated hundreds of thousands of citations in academia.

The Cohere team is a collective of college dropouts, PhDs, alumni of big tech and scrappy start-ups, new grads and career pivots, who believe a diverse team is the key to a safer, more responsible technology. At Cohere, work isn’t the opposite of play, as we build the future of language AI with team members on almost every continent in the world, working from high rises, cabins, tour buses, and dog-friendly offices.

There’s no better time to herald the next step with us as we shape the future of Generative AI.

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.
