Sr. 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.
