Senior Software Engineer, Agent Infrastructure

Cohere is the leading security-first enterprise AI company. We build cutting-edge foundation AI models and end-to-end products that are designed to solve real-world business problems. We’re training and deploying frontier models for enterprises who are building AI systems. We believe that our work is instrumental to the widespread adoption of AI and we are looking for folks that want to be part of that.

We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. Cohere is a team of researchers, engineers, designers, and more, who are all passionate about their craft.

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

We’re building the next generation of agentic AI infrastructure s team sits at the intersection of ML systems, distributed infrastructure, and developer experience, creating the platform that powers autonomous AI agents at scale.

You’ll work on hard, forward-looking problems with few established patterns, including secure code execution, agent state management, model routing, identity and authentication, and resource management for long-running agent workflows. This role is a strong fit for someone who combines systems depth with ML intuition. You should be comfortable building reliable infrastructure, thinking through distributed systems tradeoffs, and understanding how emerging agentic capabilities shape platform design.

• Secure execution environments for agent-generated code
• Identity, authentication, and trust boundaries for agents
• Model routing and orchestration across different model types and environments
• Rate limiting, quotas, and resource management for agent workflows
• State management, memory, and file system abstractions for agents.

• Turn emerging ML research ideas into production-ready infrastructure
• Build core platform capabilities for execution, storage, and state management
• Prototype and evaluate new technologies, then help decide what should move into production
• Partner with research teams to shape infrastructure based on what future agent systems will need

• Experience building production ML infrastructure with strong systems fundamentals
• Hands-on work with agentic systems, multi-agent workflows, or agent development frameworks
• Familiarity with model routing and LLM provider frameworks across different model types and environments
• Experience with scalable, fault-tolerant distributed systems and Kubernetes
• A track record of moving quickly on prototypes and making good decisions about productionization.

• Experience across on-prem, private cloud, and public cloud environments
• Familiarity with storage systems, embedded databases, or file system abstractions
• Experience with code execution sandboxes such as gVisor, Firec
