Cohere is hiring a senior full-stack engineer for its Internal Applications team, which builds tooling that helps annotators, ML researchers and product managers create better models. The work spans browser and server code, resilient mission-critical systems, and removing engineering roadblocks, alongside pairing, architecture discussions and documentation. The posting asks for experience shipping products with many stakeholders, comfort across the stack with Next.js, TypeScript, React and Python, and hands-on complex SQL. Cohere describes itself as remote-friendly, with offices in several cities.
