Runpod is a cloud platform that provides on-demand GPU compute and managed infrastructure tailored for AI development and deployment. It offers GPU "Pods" across 31 global regions, serverless GPU endpoints for low-latency inference, multi-node GPU clusters for distributed training, and a hub for deploying open-source models and templates. Runpod emphasizes fast startup (sub-200ms cold starts), autoscaling from zero to thousands of workers, support for 30+ GPU SKUs, and tooling for the full AI lifecycle from experiment to production, targeting developers and enterprise AI teams.

📋 Description

• Design and implement robust workload and network isolation architectures for RunPod's multitenant GPU bare-metal and virtualized environments. • Harden Linux kernel configurations, container runtimes (e.g., Docker, containerd), and orchestration layers (e.g., Kubernetes) against breakouts and privilege escalation. • Conduct deep-dive security assessments and penetration testing specifically targeting our hypervisor, network stack, and hardware interfaces. • Write code (primarily C, Go, or Rust) to implement custom security controls, telemetry, and fixes at the OS and infrastructure level. • Evaluate and mitigate security considerations specific to GPU architecture, PCIe pass-through, and shared memory spaces. • Serve as the technical escalation point for infrastructure-level security incidents, developing forensic capabilities for ephemeral container environments.

🎯 Requirements

• 5+ years of experience in infrastructure or systems-level security engineering. • Extensive knowledge of Linux kernel internals (cgroups, namespaces, eBPF, SELinux/AppArmor). • Deep understanding of virtualization technologies (KVM, QEMU) and workload/network isolation techniques in multitenant environments. • Strong systems-level programming skills in C, Go, Rust, or Python. • Familiarity with GPU architecture and hardware-level security considerations. • Experience in securing bare-metal cloud infrastructure and mitigating lower-level CVEs.
