Senior Member of Technical Staff, Multimodal AI

About Us

Cohere is the leading security-first enterprise AI company. We build cutting-edge foundation AI models and end-to-end products designed to solve real-world business problems. We train and deploy frontier models for enterprises building AI systems, believing our work is instrumental to the widespread adoption of AI. We obsess over what we build, with each team member contributing to increasing the capabilities of our models and the value they drive for customers.

Cohere is a global technology company headquartered in Toronto, with key offices in London, New York City, San Francisco, Montreal, Paris, Berlin, and Seoul.

About the Role

At Cohere, we believe in the power of multimodal AI to revolutionize how we interact with technology. Our engineering teams push boundaries, and we're looking for talented individuals to join us. With an exceptional ratio of compute resources to engineers, we provide an ideal environment for exploration, innovation, and shaping the future of AI.

In July 2025, Cohere's Multimodal team introduced Command A Vision, a flagship vision-language model built for business. Key highlights include:

• Consistently outperforms major models like Llama 4 Maverick, Mistral Medium/Pixtral Large, and GPT-4 (83.1% average benchmark, including 73.5% on MathVista and 90.9% on ChartQA).
• Built for the real world: 112B parameters running on just 2 GPUs.
• Open weights available on HuggingFace.

With a focused team, breakthrough performance doesn't require breakthrough compute. Join us to focus on what truly matters.

Responsibilities
