More than one million developers, from indie researchers to teams running frontier models in production, use Runpod to experiment, train, fine-tune, deploy, and scale AI on one platform. The platform has processed more than 20 billion inference requests. We closed a $100M Series A in June 2026. We're at an inflection point for AI infrastructure, and we're building the platform the next generation of developers will depend on. Learn more in our CEO's funding announcement: https://www.runpod.io/blog/one-million-developers.\nWe're a small, remote-first team. We take ownership seriously, move fast, and ship work that more than a million developers rely on every day. We're looking for people who care deeply, build with urgency, and want to matter at scale.\nAs Runpod continues to revolutionize the GPU cloud computing landscape, we are seeking a systems-focused Cloud Infrastructure Security Engineer. This critical position is instrumental in safeguarding our bare-metal and virtualized environments, ensuring the absolute security, multi tenant isolation, and integrity of our underlying GPU cloud infrastructure.\nThe ideal candidate possesses deep knowledge of Linux systems, kernel internals, hypervisors, and containerization. You will focus on the lowest levels of our stack-preventing tenant breakouts, securing GPU hardware allocations, and building resilient infrastructure to support AI and machine learning workloads.\nRunpod is seeking an innovative security engineer who thrives at the systems layer. You will operate with an Attacker's Mindset, actively hunting for ways to break container and virtualization boundaries, and then writing the low-level code to patch them.\nResponsibilities:\nSystems Isolation: Design and implement robust workload and network isolation architectures for RunPod's multitenant GPU bare-metal and virtualized environments.\n\nKernel & Container Security: Harden Linux kernel configurations, container runtimes (e.g., Docker, containerd), and orchestration layers (e.g., Kubernetes) against breakouts and privilege escalation.\n\nInfrastructure Threat Modeling: Conduct deep-dive security assessments and penetration testing specifically targeting our hypervisor, network stack, and hardware interfaces.\n\nActive Defense: Write code (primarily C, Go, or Rust) to implement custom security controls, telemetry, and fixes at the OS and infrastructure level.\n\nHardware Security: Evaluate and mitigate security considerations specific to GPU architecture, PCIe pass-through, and shared memory spaces.\n\nIncident Response: Serve as the technical escalation point for infrastructure-level security incidents, developing forensic capabilities for ephemeral container environments.\n\nRequired Qualifications:\n5+ years of experience in infrastructure or systems-level security engineering.\n\nExtensive knowledge of Linux kernel internals (cgroups, namespaces, eBPF, SELinux/AppArmor).\n\nDeep understanding of virtualization technologies (KVM, QEMU) and workload/network isolation techniques in multitenant environments.\n\nStrong systems-level programming skills in C, Go, Rust, or Python.\n\nFamiliarity with GPU architecture and hardware-level security considerations.\n\nExperience in securing bare-metal cloud infrastructure and mitigating lower-level CVEs.\n\nPreferred Qualifications:\nContributions to open-source systems security projects or virtualization research.\n\nExperience writing or deploying eBPF-based security tooling.\n\nDeep knowledge of low-level networking protocols and virtualized network security.\n\nWhat You’ll Receive:\nThe competitive base pay for this position ranges from ($152,000 - $175,000). This salary range may be inclusive of several career levels at Runpod and will be narrowed during the interview process based on a number of factors, including the candidate’s experience, qualifications, and location\n\nMeaningful equity in a fast-growing company- everyone on the team receives stock options - your impact drives our growth, and you share in the upside.\n\nGenerous medical, dental & vision plans\n\nFlexible PTO- take the time you need to recharge\n\nMost roles are remote work first with an inclusive, collaborative teams utilizing slack as the main form of internal communication\n\nJoin a passionate team on the cutting edge of AI infrastructure - where culture, learning, and ownership are at the heart of how we scale.\n\n$1,200 Home Office & Equipment Stipend- We set you up for success from day one with gear and support to create your ideal workspace\n\nRunpod is committed to maintaining a workplace free from discrimination and upholding the principles of equality and respect for all individuals.
