Infrastructure Security Engineer (Bare Metal & Platform)

SpaceXAI is seeking a hands-on Infrastructure Security Engineer to build and secure infrastructure from bare metal through the platform and application stack.

Responsibilities

• Design and implement secure bare-metal and private-cloud architectures including servers, storage, out-of-band management, and BIOS/UEFI/BMC firmware posture
• Harden physical and virtual fleets with OS baselines for Linux/Windows, CIS benchmarks, patch and vulnerability management, and secure boot / measured boot where applicable
• Perform hands-on work across 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 including site-to-site VPN, Direct Connect / Interconnect / ExpressRoute, SD-WAN, and zero-trust access
• Manage identities and privileged access across Active Directory / LDAP / Kerberos and cloud IAM (federation, SAML/OIDC, PAM)
• Support security assessments and audits for physical, on-premises, and hybrid infrastructure
• Monitor and remediate infrastructure to meet regulations and best practices (e.g., PCI, NIST CSF, GDPR, HIPAA)
• Define 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 with embedded security controls, especially Puppet
• Work with development teams to integrate security best practices into CI/CD pipelines
• Secure and enhance CI/CD pipelines, integrating and maintaining 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 ingesting on-premises network, host, and cloud telemetry for reliable alerting
• Build, deploy, and maintain security operations infrastructure using Python, Terraform, and Puppet
• Create 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, from issue identification through implementation
• Stay current on emerging threats and mitigations for bare-metal, firmware, network, and hybrid-cloud infrastructure

Requirements

• Bachelor's degree in Computer Science, Cybersecurity, or related field
• 3–5 years of experience in infrastructure security, platform security, or related hands-on roles
• Proven experience securing bare-metal, data-center, or private-cloud environments (not cloud-only resumes)
• Hands-on experience with firmware, BMC/iDRAC/iLO, PXE/Kickstart provisioning, and hardware lifecycle security
• Strong proficiency with Puppet for configuration management and fleet hardening in production
• Strong understanding of network security concepts and protocols, including hands-on experience with firewalls, segmentation, and hybrid connectivity
• Experience with hybrid identity (AD/LDAP or similar) integrated or federated with cloud IAM
• Experience with Infrastructure as Code (e.g., Terraform) applied to physical or VM fleets
• Familiarity with containerization and Kubernetes security implications, including on-premises or bare-metal clusters
• Experience with languages for automation and tooling (e.g., Python, Bash, Golang)
• Familiarity with regulatory compliance requirements (e.g., GDPR, HIPAA, PCI DSS, NIST CSF)
• Experience in banking, money transmission, P2P payments, or similarly regulated financial platforms
• Proactive mindset with strong ownership, critical thinking, and problem-solving
• Located in the SF Bay Area, Austin, New York, Palo Alto, or Seattle, or willing to relocate to a US office
