Job description

About Enclosure

Enclosure is the world’s first superintelligence security lab focused on preventing the sabotage, escape, and theft of ASI. We are building ASI-grade security for model weights, and nation-state-grade security for data centers.

We’re backed by leaders across OpenAI, Anthropic, Google DeepMind, SpaceXAI, CoreWeave, NVIDIA, other frontier AI labs, and the national security community (including former NSA and intelligence community leadership). We are frontier AI, cybersecurity, quantum security, and national security researchers.

About the Role

Enclosure is hiring an exceptional GPU security engineer or researcher. You'll own a significant part of our GPU security research as an IC. We care less about degrees and more about a track record of exploration, curiosity, and grit.

Requirements

This role requires deep experience in multiple of the following areas:

• GPU architecture, memory, virtualization, or isolation

• High-performance interconnects and distributed GPU systems

• PCIe, DMA, IOMMU, device assignment, or accelerator passthrough

• Hypervisors, confidential computing, or multi-tenant compute

• Linux kernels, device drivers, firmware, or low-level systems

• Vulnerability research, side channels, reverse engineering, or exploit development

• Security at the hardware-software boundary

What Sets You Apart

We're especially excited if you:

• Demonstrate strong engineering judgment in the systems you've built

• Get excited by hard problems and the challenge of figuring them out

• Are highly adaptive and comfortable with how quickly the frontier shifts

• Have evidence of self-directed technical work, such as open-source contributions, technical writing, tools, packages, or public projects with strong systems thinking

• Communicate with clarity and directness

• Bring a humble, low-ego attitude and care deeply about helping the team win
