• Design, build, and support tooling, automation, and infrastructure to maximize the reliability, scalability, and performance of Navan Cognition.
• Proactively identify, mitigate, and resolve issues, leveraging AI-driven insights and automation where possible.
• Develop robust monitoring, alerting, and incident response strategies; ensure actionable observability across all critical systems.
• Drive best practices in CI/CD, Infrastructure-as-Code, environment provisioning, and disaster recovery.
• Collaborate closely with engineering teams to build, deploy, and maintain highly available services in production.
• Take responsibility for uptime, reliability, and the operational excellence of Navan Cognition.
