Senior Infrastructure Security Engineer

We’re hiring a Senior Infrastructure Security Engineer to secure the foundation of fal.ai http://fal.ai’s compute platform. You’ll own security below the application layer: the Linux kernel, the hypervisors and sandboxes that isolate workloads, GPU drivers and firmware, and the hosts that run them. You’ll harden the stack, strengthen isolation against untrusted code, and help make GPU compute safe at scale. Proficiency in building with and using AI is central to this role.
