CoreWeave is hiring a Senior Software Engineer to design, build, and evolve secure sandboxed runtime environments for workloads running on Kubernetes. Your work will focus on runtime isolation, performance, and security, developing platforms that integrate container runtimes, lightweight virtual machines, and virtualization technologies to support GPU-accelerated workloads in multi-tenant environments.
What You'll Do
- Design GPU-aware sandboxing and scheduling strategies.
- Optimize containerization and I/O performance for latency-sensitive workloads.
- Build systems capable of safely executing untrusted or shared GPU workloads.
- Contribute to architectural decisions across Linux internals, container runtimes, virtualization layers, and GPU drivers to ensure long-term scalability and operational excellence.
What We're Looking For
- 3+ years of experience in systems, platform, infrastructure, or production engineering roles building and operating software at scale.
- Strong hands-on experience with Kubernetes, container orchestration, and cloud-native architectures, including building Kubernetes-native components.
- Demonstrated experience designing, implementing, or operating secure execution environments such as container runtimes, sandboxed workloads, or virtualized systems.
- Practical experience with lightweight virtualization and sandboxing technologies (e.g., Kata Containers, gVisor, KubeVirt, QEMU, or similar).
- Experience supporting or optimizing GPU-accelerated workloads in multi-tenant environments, including knowledge of GPU scheduling, isolation, device passthrough, mediated devices, or GPU virtualization concepts.
- Proficiency in systems-oriented programming (Go, C/C++, Rust, or Bash) with a strong understanding of Linux internals and operating system behavior.
- Experience diagnosing and resolving complex performance, reliability, or isolation issues across containers, virtual machines, and underlying infrastructure.
- Experience conducting profiling, benchmarking, and performance tuning across runtime, virtualization, and GPU stacks.
Nice to Have
- 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.
Technical Stack
- Kubernetes, Container runtimes, GPU infrastructure
- Linux, Go, C/C++, Rust, Bash
- Kata Containers, gVisor, KubeVirt, QEMU
Team & Environment
This role sits at the intersection of container runtimes, lightweight virtualization, GPU infrastructure, and Linux systems engineering. You will partner closely with security, platform, and GPU infrastructure teams.
