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.
Preferred Qualifications
- 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.
