Member of Technical Staff, Post-Training
As a Member of Technical Staff, Post-Training at Cohere, you will advance the state-of-the-art for model post-training, shipping models to production and bridging the gap between research and production. You will design and write high-performant, scalable software for training models, consistently post-training them to reach SOTA level performance. This role involves coordinating with specialist teams, implementing performance optimization techniques for training cycles, and experimenting with ideas on supercompute and data infrastructure.
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!
Advance the state of the art for model post training, ship state of the art models to production, and bridge the gap between research and production. We have one of the highest ratio of compute to engineers in the world. We do not delineate strongly between engineering and research. Everyone will contribute to writing production code and supporting our research effort depending on individual interest and organisational needs. We have all the compute, data, and talent available for you to do your best work.
