Member of Technical Staff, Post-Training
Role Overview
This senior-level role involves designing and writing high-performance software for training AI models, focusing on post-training to achieve state-of-the-art performance. You will work in a collaborative team environment, coordinating with specialist groups to enhance model capabilities and implementing techniques to improve training cycles. The impact includes advancing AI research and bridging the gap between research and production by shipping models to production.
Perks & Benefits
The role is remote-flexible with offices in multiple cities and a co-working stipend, offering a supportive culture with an open and inclusive work environment. Benefits include full health and dental coverage, mental health budget, 6 weeks of vacation, and personal enrichment allowances for arts, fitness, and workspace improvement. Career growth is emphasized through collaboration with top researchers and access to extensive compute resources, with no strict time zone expectations implied, typical for remote tech roles.
Full Job Description
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?
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.
Please Note: We have offices in London, Paris, Toronto, San Francisco and New York but also embrace being remote-friendly!
As a Member of Technical Staff, you will:
Design and write high-performant and scalable software for training models.
Consistently post-train the models to reach SOTA level performance.
Coordinate with other specialist teams (Agentic, Code…) to produce models that have strong all encompassing performance.
Craft and implement techniques to improve the performance and results of our training cycles both on the SFT and the RL regime.
Research, implement, and experiment with ideas on our supercompute and data infrastructure.
Learn from and work with the best researchers in the field.
You may be a good fit if you have:
Extremely strong software engineering skills.
Proficiency in Python and related ML frameworks such as JAX, Pytorch and XLA/MLIR.
Experience with distributed training infrastructures (Kubernetes, Slurm) and associated frameworks (Ray).
Experience using large-scale distributed training strategies.
Hands on experience on training large model at scale.
Hands on experience with the post training phase of model training, with a strong emphasis on performance optimisation.
Bonus: paper at top-tier venues (such as NeurIPS, ICML, ICLR, AIStats, MLSys, JMLR, AAAI, Nature, COLING, ACL, EMNLP).
* 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!
We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities. Should you require any accommodations during the recruitment process, please submit an Accommodations Request Form, and we will work together to meet your needs.
