About the Role

As a GPU & Runtime Systems Engineer, you will design, build, and evolve secure sandboxed runtime environments for Kubernetes workloads, focusing on runtime isolation, performance, and security. You will integrate container runtimes, lightweight VMs, and virtualization technologies to support GPU-accelerated workloads in multi-tenant environments. Day-to-day, you'll develop GPU-aware sandboxing and scheduling strategies, optimize containerization and I/O performance for latency-sensitive workloads, and influence architectural decisions across Linux internals, container runtimes, virtualization layers, and GPU drivers.

Responsibilities

Design and implement secure execution environments for containerized and virtualized workloads.
Build GPU-aware scheduling, isolation, and resource management strategies for multi-tenant workloads.
Optimize container, VM, and I/O performance across GPU-accelerated workloads.
Conduct profiling, benchmarking, and performance tuning for runtime, virtualization, and GPU stacks.
Contribute to architectural decisions across Linux internals, container runtimes, virtualization layers, and GPU drivers.
Collaborate with security, platform, and infrastructure teams to define and implement runtime isolation and performance standards.

Requirements

3+ years of experience in systems, platform, infrastructure, or production engineering at scale.
Strong hands-on experience with Kubernetes, container orchestration, and cloud-native architectures, including controllers, operators, or scheduling extensions.
Experience designing, implementing, or operating secure execution environments (container runtimes, sandboxed workloads, or virtualized systems).
Practical experience with lightweight virtualization and sandboxing technologies (e.g., Kata Containers, gVisor, KubeVirt, QEMU).
Experience supporting GPU-accelerated workloads in multi-tenant environments, including GPU scheduling, isolation, device passthrough, mediated devices, or virtualization.
Proficient in systems-oriented programming (Go, C/C++, Rust, Bash) with strong Linux internals knowledge.
Skilled at diagnosing and resolving complex performance, reliability, or isolation issues across containers, VMs, and infrastructure.
Experienced in profiling, benchmarking, and tuning performance across runtime, virtualization, and GPU stacks.
Experience building systems for safely executing untrusted or sensitive workloads in shared environments.
Familiarity with GPU drivers and low-level virtualization or I/O optimization techniques.
Experience defining threat models and implementing runtime security policies in multi-tenant systems.
This position requires access to export controlled information. To conform to U.S. Government export regulations applicable to that information, applicant must either be (A) a U.S. person, defined as a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (green card holder), (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, (B) eligible to access the export controlled information without a required export authorization, or (C) eligible and reasonably likely to obtain the required export authorization from the applicable U.S. government agency.
