Infrastructure Security Engineer (Bare Metal & Platform)

SpaceXAI is seeking a hands-on Infrastructure Security Engineer to help build and protect infrastructure from the physical layer through the platform and application stack. This role is focused on hardening bare metal and private-cloud foundations, embedding security into how systems are built and run, and securing hybrid connectivity across on-prem and cloud environments.

Work onsite in New York, NY, with a $100,000 - $258,000 USD base salary and a package that includes equity, comprehensive medical, vision, and dental coverage, retirement benefits, and additional discounts and perks.

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 Linux/Windows OS baselines, CIS benchmarks, patch and vulnerability management, and secure boot or measured boot where applicable
• Perform hands-on work across firmware and lifecycle security using BMC/iDRAC/iLO, PXE/Kickstart provisioning, and related hardware controls
• Build and secure network foundations on real hardware, including segmentation, load balancers, DNS, PKI, NAC, and IDS/IPS
• Own security for hybrid connectivity between on-prem and cloud using site-to-site VPN, Direct Connect / Interconnect / ExpressRoute, SD-WAN, and zero-trust access
• Manage identities and privileged access across hybrid environments using Active Directory / LDAP / Kerberos and cloud IAM, including federation, SAML/OIDC, and PAM
• Support security assessments and audits of physical, on-premises, and hybrid infrastructure
• Monitor and remediate infrastructure to align with regulations and best practices such as PCI, NIST CSF, GDPR, and HIPAA
• Design and implement secure container and Kubernetes standards for bare metal and private cloud, including RBAC, network policy, and secrets
• Develop and maintain Infrastructure as Code and configuration management with an emphasis on Puppet, including embedded security controls for physical and virtual fleets
• Partner with development teams to integrate security best practices into CI/CD pipelines
• Secure and enhance CI/CD pipelines by maintaining and integrating 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
• Create dashboards and alerts from security metrics across physical and platform layers
• Maintain infrastructure security policies, standards, and procedures from metal through platform
• Own security projects end to end, from identifying issues to implementing solutions
• Stay current with emerging threats and mitigations across bare-metal, firmware, network, and hybrid-cloud infrastructure

Requirements

• Bachelor's degree in Computer Science, Cybersecurity, or a 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)
• Hands-on experience with firmware, BMC/iDRAC/iLO, and PXE/Kickstart provisioning, including 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 work with firewalls, segmentation, and hybrid connectivity
• Experience with hybrid identity such as AD/LDAP integrated or federated with cloud IAM
• Infrastructure as Code experience (e.g., Terraform) applied to physical or VM fleets
• Familiarity with containerization and Kubernetes security implications for on-premises or bare-metal clusters
• Experience with automation and tool development using languages such as Python, Bash, and Golang
• Familiarity with regulatory compliance requirements including GDPR, HIPAA, PCI DSS, and NIST CSF
• Experience with 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

Benefits

• Equity
• Comprehensive medical, vision, and dental coverage
• Access to a 401(k) retirement plan
• Short & long-term disability insurance
• Life insurance
• Various other discounts and perks
• $100,000 - $258,000 USD base salary

Preferred Skills and Experience

• Deep expertise operating and securing physical server fleets, colo, or private cloud (VMware, OpenStack, Proxmox, Nutanix, or similar)
• Relevant security certifications (e.g., CCSP, CSSK, OSCP, or a network/cloud security specialty)
• Strong proficiency with Python and Terraform on production fleets
• Deep expertise in Kubernetes and container security on bare metal or private cloud
• Experience with multi-cloud and cloud-to-on-prem security
• Knowledge of CI/CD best practices and hands-on GitHub Actions or equivalent
• Experience with observability and security operations tooling (e.g., Prometheus, Grafana, CloudWatch, Karma, and SIEM platforms such as Wazuh)
• Experience building custom security tools or integrations
• Interest in leveraging AI for infrastructure security monitoring and automation
• Contributions to open-source infrastructure or security projects
• Experience securing AI/ML and GPU workloads on bare metal or hybrid infrastructure
