Design and implement secure bare-metal and private-cloud architectures (servers, storage, out-of-band management, BIOS/UEFI/BMC firmware posture)
Harden physical and virtual fleets: OS baselines (Linux/Windows), CIS benchmarks, patch and vulnerability management, and secure boot / measured boot where applicable
Hands-on firmware, BMC/iDRAC/iLO, PXE/Kickstart provisioning, and hardware lifecycle security
Build and secure network foundations: segmentation, load balancers, DNS, PKI, NAC, and IDS/IPS on real hardware
Own hybrid connectivity between on-premises and cloud (site-to-site VPN, Direct Connect / Interconnect / ExpressRoute, SD-WAN, zero-trust access)
Manage identities and privileged access across Active Directory / LDAP / Kerberos and cloud IAM (federation, SAML/OIDC, PAM)
Assist with security assessments and audits of physical, on-premises, and hybrid infrastructure
Monitor and remediate infrastructure to comply with regulations and best practices (e.g., PCI, NIST CSF, GDPR, HIPAA)
Design and implement secure container and Kubernetes standards on bare metal and private cloud (not only managed EKS/GKE/AKS), including RBAC, network policy, and secrets
Develop and maintain Infrastructure as Code and configuration management—especially Puppet—with embedded security controls for physical and virtual fleets
Collaborate with development teams so security best practices are integrated into CI/CD pipelines
Secure and enhance CI/CD pipelines; integrate and maintain code and image scanning platforms
Monitor and respond to security events and incidents spanning bare metal, network devices, hosts, and hybrid cloud
Maintain SIEM data pipelines that ingest on-premises network, host, and cloud telemetry for reliable alerting
Build, deploy, and maintain security operations infrastructure using Python, Terraform, and Puppet
Develop dashboards and alerts from security metrics across physical and platform layers
Develop and maintain infrastructure security policies, standards, and procedures from metal through platform
Own security projects end to end: identify issues and implement solutions
Stay current with emerging threats and mitigations for bare-metal, firmware, network, and hybrid-cloud infrastructure
