Résumé du poste

SpaceXAI seeks an hands-on Infrastructure Security Engineer to design, secure, and harden our bare-metal and private-cloud foundations—from servers and networks to orchestration and container platforms. You’ll embed security into CI/CD, manage firmware and hardware lifecycle security, and ensure compliance with PCI, NIST CSF, GDPR, and HIPAA across data centers, colo, and hybrid environments.

The role requires leadership in securing physical and virtual fleets, implementing secure core OS

Qualifications

• Bachelor's degree in Computer Science, Cybersecurity, or a related field.
• 3–5 years of infrastructure security experience.
• Proven experience securing bare-metal, data-center, or private-cloud environments.
• Hands-on firmware, BMC/iDRAC/iLO, and hardware lifecycle security.
• Strong Puppet for fleet hardening and config management.

Responsabilités

• Design secure bare-metal and private-cloud architectures (servers, storage, out-of-band management).
• Harden OS baselines, patching, and secure boot workflows.
• Manage firmware, BMC/iDRAC/iLO provisioning and hardware lifecycle security.
• Secure network foundations: segmentation, load balancers, DNS, PKI, NAC, and IDS/IPS on real hardware.
• Own hybrid connectivity between on-premises and cloud and manage IAM across AD/LDAP and cloud IAM.
• Assist with security assessments and audits of physical, on-premises, and hybrid infra.
• Monitor and remediate infrastructure to comply with PCI, NIST CSF, GDPR, HIPAA.

Description du poste

Infrastructure Security Engineer (Bare Metal & Platform)

SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

ABOUT THE ROLE:

We are seeking a hands-on Infrastructure Security Engineer to build and secure SpaceXAI’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 SpaceXAI, 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—\"bolted on after the fact\".

RESPONSIBILITIES:

• 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

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

BASIC QUALIFICATIONS:

• 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 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 work 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 (e.g., Python, Bash and Golang) for automation and tool development
• 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 skills
• Located in the SF Bay Area, Austin, New York, Palo Alto, or Seattle, or willing to relocate to a US office

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, network or 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 tools; hands‑on GitHub Actions or equivalent
• Experience with observability and security operations tooling (e.g., Prometheus, Grafana, CloudWatch, Karma; 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

COMPENSATION AND BENEFITS:

$100,000 - $258,000 USD

Base salary is just one part of our total rewards package at SpaceXAI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.
