About the Team

• Administer Linux-based platform environments, including upgrades, patching, troubleshooting and performance monitoring.
• Integrate applications with supporting platform services, including object storage, artifact repositories and Git repositories.
• Support secure platform operations, including security scanning, vulnerability remediation, certificate management, access controls and DevSecOps practices.
• Troubleshoot platform, pipeline and environment issues in collaboration with development, test and security teams.
