Member of Technical Staff - Security Eng.
About The Position
Prime Intellect is building an open superintelligence stack: infrastructure that gives AI teams access to compute, environments, evaluations, secure sandboxes, high-performance training, and deployment in a unified platform. The company builds open frontier AI models and the full-stack platform used to train them. The Security Engineering role protects customers’ proprietary models, training data, and compute across hosted, private, and on-prem environments. The position owns security engineering across GPU infrastructure, the training platform, and sandboxes, with a focus on isolation, access control, and data residency for frontier labs, large enterprises, and sovereign AI programs. This is a lead-level individual contributor role based in the San Francisco office, with potential to manage people over time. The role works closely with the security team, CTO, and Head of Engineering.
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.
- Experience responding to real security incidents and ability to explain what happened, what was missed, and what was changed.
- Knowledge of security weaknesses in Linux, cloud IAM, networking, and container boundaries, and experience shipping production-ready controls.
- Ability to identify security vulnerabilities and implement fixes through code, detections, tooling, and infrastructure changes.
- Ability to take ownership of ambiguous problems, make practical risk decisions, and communicate clearly with stakeholders.
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.
Benefits
- 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.
- Opportunity to work with a talented, mission-driven team building open superintelligence.
