How to Apply for Site Reliability Engineer - Cybersecurity

at xAI

🏢 About xAI

xAI operates with a unique flat engineering structure focused on solving fundamental problems in AI and understanding the universe, rather than chasing commercial products. This creates an environment where engineers work directly on cutting-edge research infrastructure with minimal bureaucracy. The mission-driven focus on advancing human knowledge through AI makes it appealing for those wanting meaningful technical impact.

About This Role

This Site Reliability Engineer role specifically focuses on cybersecurity within xAI's hybrid cloud environment, securing mission-critical AI applications and infrastructure. You'll be responsible for implementing security controls, container standards, and automation to protect sensitive AI systems while enabling developer productivity. The role directly supports xAI's mission by ensuring the security and reliability of systems that advance AI research.

💡 A Day in the Life

A typical day involves reviewing security alerts from your Prometheus/Grafana monitoring stack, implementing Terraform changes to harden infrastructure, collaborating with AI researchers to secure their containerized workloads, and automating security controls using Python and Puppet. You'll balance proactive security improvements with responding to incidents in xAI's mission-critical AI systems.
