About the role
We’re hiring a Senior Infrastructure Security Engineer to secure the foundation of 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. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- AI fluency: you use LLMs, agents, and AI coding tools daily to review code, build tooling, and accelerate vulnerability research
- 5+ years in systems or security engineering, with deep hands-on work in the Linux kernel, hypervisors, or device drivers
- Fluent in kernel C, and comfortable in Rust, Go, or Python for tooling
- Strong grasp of virtualization internals: KVM, VFIO, IOMMU/DMA protection, and the tradeoffs between containers, sandboxes, and microVMs
- Has shipped hardening that runs in production at fleet scale
- Has found, triaged, or fixed real vulnerabilities in low-level code and can explain the exploit path
More about this role
fal is the generative media ecosystem powering the next generation of AI products. We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise. For developers and enterprises, fal is the foundation that makes generative media not just possible, but practical: a unified platform where high-performance inference, orchestration, and observability come together to unlock new categories of AI-native products.
As generative media reshapes industries across a market projected to grow by hundreds of billions over the next decade, fal is becoming the ecosystem that ambitious teams build on.
