> Own end-to-end security R&D projects building novel infrastructure like isolated clusters and cryptographic verification for AI safety. Requires 7+ years engineering experience, Python/systems languages, cloud/Kubernetes, and cross-functional execution in ambiguous environments.

## Job Description

## Current Project Areas
- Designing and operating mock high-assurance research environments under extreme isolation.
- Exploring cryptographic verification of model integrity using zero-knowledge proofs.
- Assessing confidential computing feasibility across model lifecycle.
- Piloting AI-assisted security tooling (vulnerability discovery, automated patching, anomaly detection).
- Prototyping API-only access regimes.

## What You'll Do
- Own end-to-end execution of Security Labs projects: refine hypothesis, design experiment, build prototype, run pilot, write results.
- Build novel security infrastructure (isolated clusters, hardened access controls, cryptographic layers).
- Drive successful experiments to production scale.
- Embed with research teams to stress-test workflows under extreme security controls.
- Evaluate and integrate emerging security technologies with vendors and research groups.
- Produce decision-ready writeups informing security architecture.
- Maintain pain-point registry and feasibility assessments.
- Scope and prioritize next Labs projects.

## You May Be a Good Fit If You Have
- 7+ years software or security engineering experience with production systems.
- Experience with pilots, prototypes, or applied research.
- Strong programming in **Python** and systems language (**Go**, **Rust**, or **C/C++**).
- Hands-on with cloud infrastructure (**AWS**, **GCP**, **Azure**), **Kubernetes**, networking.
- Cross-functional execution skills.
- Clear written communication.
- Comfort with ambiguity and iteration.
- Curiosity about nation-state adversary defense.
- Passion for AI safety.
- Bachelor's degree in Computer Science or related field (or equivalent).

## Strong Candidates May Also Have
- Offensive security, red teaming, or security research experience.
- Airgapped or high-side environments familiarity.
- Applied cryptography knowledge (**zero-knowledge proofs**, attestation, secure enclaves, **TPMs**, confidential computing).
- ML infrastructure experience (training, inference, model packaging).
- Security systems in rapid iteration environments.
