Senior Software Engineer II

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 for GPU-accelerated workloads.
• Conduct profiling, benchmarking, and performance tuning across runtime, virtualization, and GPU stacks.
• Contribute to architectural decisions involving 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, cloud-native architectures, 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 such as Kata Containers, gVisor, KubeVirt, or QEMU.
• Experience supporting GPU-accelerated workloads in multi-tenant environments, including GPU scheduling, isolation, device passthrough, mediated devices, or virtualization.
• Proficiency in systems-oriented programming with Go, C/C++, Rust, or Bash and strong Linux internals knowledge.
• Ability to diagnose and resolve complex performance, reliability, or isolation issues across containers, virtual machines, and infrastructure.
• Experience profiling, benchmarking, and tuning performance across runtime, virtualization, and GPU stacks.
• Preferred experience safely executing untrusted or sensitive workloads in shared environments, working with GPU drivers and low-level virtualization or I/O optimization, and defining threat models and runtime security policies.
