Job description

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 talented and motivated Infrastructure Security Engineer to join our security team. In this role, you will design, implement, and maintain secure cloud and hybrid infrastructure, and ensure the integrity of our cloud-native applications.

This role focuses on securing critical infrastructure across multi-cloud 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, hardening platforms at scale, and partnering closely with engineering teams so security is embedded in how we build and run systems—not bolted on after the fact.

RESPONSIBILITIES:

Cloud & infrastructure security

  • Design and implement secure cloud architectures across multiple cloud platforms (e.g., AWS, GCP, Azure)
  • Build and secure mission-critical applications in hybrid cloud and on-premises environments
  • Develop and maintain Infrastructure as Code (IaC) templates with embedded security controls
  • Assist with regular security assessments and audits of cloud infrastructure and services
  • Implement and manage cloud security tools and services (e.g., CSPM, CWPP, CASB)
  • Manage identities and roles effectively across cloud and hybrid environments
  • 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 standards and automation that enable frictionless developer workflows
  • Maintain Kubernetes security aligned with current best practices
  • Collaborate with development teams to ensure security best practices are integrated into CI/CD pipelines
  • Secure and enhance CI/CD pipelines; integrate and maintain code scanning platforms

Detection, operations & tooling

  • Monitor and respond to security events and incidents in cloud and hybrid environments
  • Maintain SIEM data pipelines needed for reliable alerting
  • Build, deploy, and maintain security operations infrastructure using Python, Terraform, and configuration management (e.g., Puppet)
  • Develop dashboards and alerts from security metrics
  • Develop and maintain cloud security policies, standards, and procedures
  • Own security projects end to end: identify issues and implement solutions
  • Stay current with emerging cloud security threats and mitigation strategies
BASIC QUALIFICATIONS:
  • Bachelor's degree in Computer Science, Cybersecurity, or a related field
  • 3–5 years of experience in cloud security, infrastructure security, or related roles
  • Strong understanding of cloud security principles, compliance frameworks, and best practices
  • Proficiency in at least one cloud platform (AWS, GCP, or Azure) and associated security services
  • Proven experience securing hybrid AWS/on-premises (or multi-cloud) environments, including IAM and overall security posture
  • Experience with Infrastructure as Code tools (e.g., Terraform, CloudFormation)
  • Familiarity with containerization technologies and their security implications
  • Knowledge of network security concepts and protocols
  • Experience with scripting languages (e.g., Python, Bash) for automation and tool development
  • Proactive mindset with strong ownership, critical thinking, and problem-solving skills
  • Located in the SF Bay Area or willing to relocate
PREFERRED SKILLS AND EXPERIENCE:
  • Relevant security certifications (e.g., CCSP, CSSK, AWS Security Specialty)
  • Deep expertise in Kubernetes and container security
  • Experience with multi-cloud environments and cloud-to-cloud security
  • Knowledge of CI/CD best practices and tools
  • Familiarity with regulatory compliance requirements (e.g., GDPR, HIPAA, PCI DSS, NIST CSF)
  • Strong proficiency with Python, Terraform, and configuration management (e.g., Puppet)
  • Hands-on experience building GitHub Actions and workflows
  • Experience with observability and security operations tooling (e.g., Prometheus, Grafana, CloudWatch, Karma; SIEM platforms such as Wazuh)
  • Experience in building custom cloud security tools or integrations
  • Interest in leveraging AI for cloud security monitoring and automation
  • Contributions to open-source cloud security projects
  • Experience with securing AI/ML workloads in cloud environments
  • Experience in banking, money transmission, P2P payments, or similarly regulated financial platforms
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.
