About the company
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—not bolted on after the fact.
RESPONSIBILITIES:
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
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
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)
•

•
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
