Ship full-stack features for Cohere's secure enterprise AI workspace, North
Cohere is hiring a senior full-stack engineer, front-end leaning, for its North team — the AI workspace platform that connects agents to sensitive enterprise data under strict security constraints. The role demands production Python and React experience, prior work shipping performant RAG/agentic applications at scale, and comfort building minimal, custom code in place of popular libraries when security requirements block their use.
