Primary stack
Job description
About the Position
Prime Intellect is building the open superintelligence stack: the infrastructure frontier AI labs build internally, made available to every ambitious AI team. We are seeking a Member of Technical Staff - Security Engineer to join our team in San Francisco. This lead-level IC role will focus on securing our GPU infrastructure, training platform, and sandboxes, ensuring the protection of sensitive IP across hosted, private, and on-prem environments.
Role Impact
Our customers trust us with proprietary models, training data, and the compute that powers them. You’ll own the security engineering that makes that trust possible across our GPU infrastructure, training platform, and sandboxes.
Responsibilities
- Harden cloud, GPU, and server infrastructure across hosted and customer-controlled environments, including Linux, Kubernetes, networking, and tenant isolation.
- Build security telemetry, audit trails, detections, and actionable alerts for suspicious access, workload behavior, and data movement.
- Lead incident response from investigation and containment through recovery, postmortems, and lasting fixes.
- Own vulnerability prioritization and remediation, coordinating urgent patches with infrastructure and product teams.
- Build secure defaults for identity, secrets, data access, and deployment pipelines that meet enterprise and sovereign requirements.
- Test systems with an attacker’s mindset, run threat models and penetration tests, and turn findings into shipped improvements.
Requirements
- Experience securing critical production systems carrying sensitive customer data or proprietary IP, ideally for demanding enterprises, research labs, or private and on-prem deployments.
- Proven track record responding to real incidents. Ability to walk through what happened, what you missed, and what you changed.
- Deep knowledge of where Linux, cloud IAM, networking, and container boundaries tend to break, and experience shipping controls that hold up in production.
- Ability to find the hole and write the fix: code, detections, tooling, and infrastructure changes.
- Ownership when the problem is fuzzy, practical risk calls, and clear communication to bring people along.
Benefits and Perks
- Base salary of $150,000-300,000, plus equity.
- Full visa sponsorship and relocation support.
- Professional development budget for courses and conferences.
- Quarterly team off-sites, hackathons, conferences, and learning opportunities.
- Work with a talented, mission-driven team building open superintelligence.
