Infrastructure Security Engineer, SpaceXAI

• Bachelor's degree in computer science, cybersecurity, or other scientific discipline
• 3+ years of experience in infrastructure security, platform security, or other hands-on security roles
• Experience securing bare-metal, data-center, or private-cloud environments (not cloud-only resumes)
• Experience securing AI/ML and GPU workloads on bare metal or hybrid infrastructure

Desirable

• We are seeking a hands-on Infrastructure Security Engineer to build and secure SpaceXSI's infrastructure from the bare-metal layer up through the platform and application stack
• In this role, you will design, implement, and harden physical and private-cloud foundations—servers, networks, identity, and orchestration—and carry that security posture into containers, automation, and hybrid connectivity with public cloud
• This role focuses on securing critical infrastructure spanning data centers, colo, and hybrid environments, with work that may span platforms such as SpaceXSI, X Social, X Money, and related systems
• You’ll operate with an automation-first mindset: building secure foundations at the metal and OS layer, hardening platforms at scale, and partnering closely with engineering so security is embedded in how we build and run systems—not bolted on after the fact
• Bare metal, data center & network security:
• 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)
• Platform, containers & developer enablement:
• 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
• Detection, operations & tooling:
• 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
