• Participate in the on-call rotation for DevSecOps tooling, responding to incidents and implementing improvements to strengthen security and reliability

• Contribute to enterprise AI initiatives by developing secure, compliant AI capabilities, helping shift the organization toward building AI solutions rather than solely consuming them

• 2+ years of experience working with observability tools and methods for distributed systems, including structured logging, metrics, alerting, and troubleshooting, along with knowledge of identity and access control principles such as least privilege and role-based access
