## Description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars. SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next. INFRASTRUCTURE SECURITY ENGINEER 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 SpaceXSI, 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: 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) 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 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+ years of experience in cloud security, infrastructure security, or other security roles Experience with Infrastructure as Code tools (e.g., Terraform, CloudFormation) Experience with scripting languages (e.g., Python, Bash) for automation and tool development PREFERRED SKILLS AND EXPERIENCE: 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 Familiarity with containerization technologies and their security implications Knowledge of network security concepts and protocols Proactive mindset with strong ownership, critical thinking,
