Implement authentication mechanisms such as user login, token management, and authorization checks to maintain data integrity.
Integrate new tools to enhance North’s security capabilities and design secret management within Kubernetes clusters, including encryption and role-based access control.
Collaborate across teams to communicate security best practices to stakeholders in clear and concise ways.

Requirements

Five or more years of experience building user-facing security features in production systems.
Proven ability to ship production Python code confidently and frequently.
Deep understanding of OIDC/OAuth 2.0, JWT validation, and token lifecycle management beyond theoretical knowledge.
Hands-on experience with Kubernetes in both development and production environments.
Experience working across GCP, AWS, Azure, or hybrid and multi-cloud deployments.
Ability to work across the full technology stack and communicate security concepts clearly to non-security engineers and stakeholders.
Comfort thriving in fast-moving environments where priorities evolve, with preferred experience in AI/ML systems or LLM-based applications.
