Senior Full-Stack Engineer – North Tools & Retrieval

About the role

Join Cohere’s North platform as a Senior Full‑Stack Engineer, working on tools and retrieval capabilities that power secure, enterprise‑grade AI experiences. You will move freely across backend and frontend, delivering end‑to‑end features that enable users to upload, organize, and extend AI agents with custom skills and integrations.

Key responsibilities

• Design, build, ship, and maintain full‑stack features such as large‑scale file upload, shared knowledge bases, agent extensibility framework, and data‑sync pipelines.
• Own features end‑to‑end from technical design through implementation, testing, launch and iteration.
• Write minimal code that runs in low‑resource, security‑focused environments, often reinventing solutions without popular libraries.
• Collaborate closely with Product, UX and modeling teams to validate requirements and prototype quickly.
• Raise the engineering bar through patterns, testing discipline, code reviews and mentoring.

Required profile

• Proven experience shipping full‑stack code in Python and React at production scale.
• Comfortable working across backend and frontend in fast‑paced environments with shifting priorities.
• Experience building performant client‑side or server‑side RAG/agentic applications for large user bases.
• Product‑oriented mindset, questioning “should we build this?” before “how do we build it?”.
