Prime Intellect

Security Engineer

• Own threat modeling across our entire surface area: multi-tenant training infrastructure, sandboxed execution environments, API surfaces, and internal tooling
• Design and implement zero-trust networking, identity, and access control across distributed GPU clusters and cloud infrastructure
• Build secure-by-default patterns for our platform engineers — auth, secrets management, supply chain integrity, container hardening
• Architect tenant isolation and data boundary enforcement for hosted RL training workloads (customers run arbitrary code in our environments)
• Develop security frameworks specific to AI infrastructure: model weight protection, training data isolation, checkpoint integrity, gradient privacy
• Secure the RL training loop end-to-end — from environment execution in sandboxes to reward signal verification and model artifact storage
• Build detection and prevention for AI-specific attack vectors: prompt injection across agentic pipelines, model exfiltration, adversarial environment manipulation
• Scope, manage, and run point on external penetration tests across our platform, hosted training infrastructure, and liquid compute layer
• Build and maintain an internal red-teaming practice — automated and manual — targeting our most critical systems
• Drive vulnerability management: triage, remediation SLAs, and root cause analysis
• Build security monitoring and alerting across infrastructure (distributed clusters, Kubernetes, cloud) and application layers
• Implement runtime security for containerized training workloads and sandboxed environments
• Own incident response — build the playbooks, run the drills, lead the post-mortems
• Design audit logging and forensic capability across all customer-facing systems
• Drive SOC 2 Type II readiness and other compliance frameworks required by enterprise customers
• Own the security narrative for customer-facing materials — questionnaires, architecture reviews, trust documentation
• Partner with GTM to unblock enterprise deals that depend on security posture.
