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.

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)
