Cohere Senior/Staff Software Engineer, Developer Experience — testing and automation infrastructure for the North platform

This interview is for a Senior/Staff engineer building the automation and testing infrastructure behind Cohere's North platform — CI/CD pipelines, GitHub workflows, Helm/ArgoCD deployment tooling, and intelligent test agents that simulate real user behavior. The JD's emphasis on 5+ years of automation/testing infra experience plus expert Python and TypeScript sets the bar for depth expected here.
