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 Cyber researcher. You'll own a significant part of our cyber 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:

• Offensive security, red teaming, or computer network exploitation

• Vulnerability research and exploit development

• Linux security internals, EDR tooling, and EDR evasion techniques

• Computer network explorations and exploitation

• Offensive security tooling, payloads, implants, and capability development, including frameworks such as Kali, Metasploit, Burp Suite, XBOW, and other CLI- or web-based penetration testing tools.

• MDR experience across multiple types of incidents

• AI-system red teaming or autonomous cyber evaluation

• Reverse engineering, malware analysis, or low-level systems work

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

Why Join

Enclosure is securing the path to superintelligence.

What we offer:

• Competitive compensation package

• Ownership over research direction

• Close collaboration with frontier AI security and infrastructure teams
