Who are we?

Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises who are building AI systems to power magical experiences like content generation, semantic search, RAG, and agents. We believe that our work is instrumental to the widespread adoption of AI.

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. We like to work hard and move fast to do what’s best for our customers.

About the Role:

Are you passionate about secure-by-design software engineering? Do you want to be at the forefront of AI innovation and enterprise security? Cohere's North team is seeking a Software Engineer with a focus on security to join our mission and make a significant impact. This isn't a review-and-advise role, you'll own and ship production security features that customers rely on every day.

Your Role:

As a Senior Software Engineer with a security focus, you'll play a pivotal role in building and securing North's architecture. Your responsibilities will include:

• Software Development: Contributing to the core development of security features such as OIDC/OAuth flows and session management, ensuring North's AI agents are secure

• Secure Coding: Writing secure code to handle OIDC tokens, user claims, and sensitive data, adhering to best practices for JWT validation and encryption

• Authentication and Data Protection: Implementing authentication mechanisms including user login, token management, and authorization checks to maintain data integrity

• Tool Integration: Pulling in new tools to enhance North's security capabilities

• Dev Sec Ops: Design and implement secret management within Kubernetes clusters, including encryption and RBAC

• Cross-functional Collaboration: Demonstrate strong soft skills to communicate security best practices to stakeholders in a clear and concise manner

You may be a good fit if:

• Have 5+ years building user-facing security features in production systems

• Ship production Python confidently and frequently

• Understand OIDC/OAuth 2.0, JWT validation, and token lifecycle management deeply—not just conceptually

• Have hands-on experience with Kubernetes in both development and production environments

• Have worked across GCP, AWS, Azure, or hybrid/multi-cloud deployments

• Are comfortable working across the stack

• Communicate security concepts clearly to non-security engineers and stakeholders

• Thrive in fast-moving environments where priorities evolve

• Experience working with AI/ML systems or LLM-based applications

If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply!

We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities.
