Responsibilities
- Define and select a fleet patching strategy by evaluating live migration, snapshot and restore, kexec-based updates, live patching, in-place runtime and VMM upgrades, and other approaches.
- Model failure modes and make tradeoffs explicit, including workload impact, operational risk, non-convergence, aborts, rollback, and fleet-wide rollout safety.
- Establish metrics including guest-visible downtime, total migration time, network amplification, abortability, and time to patch the fleet.
- Design and drive the first implementation using Cloud Hypervisor and Linux microVM runtimes on x86 and arm64.
- Set technical direction and own designs from architecture and tradeoffs through implementation and review.
- Work with SRE, Compute, and security organizations on rollout, safety, and fleet operations.
- Hire and grow a new team, potentially as a technical lead or people manager.
Requirements
- Bachelor's degree in Computer Science or equivalent related experience.
- At least 8+ years of software design and development experience in infrastructure engineering, including compute, storage, or network virtualization.
- Deep experience operating live migration, live patching, or kexec-style host updates across a production fleet, or building live migration, snapshot/restore, or device-state serialization inside a hypervisor or VMM.
- Working fluency across the other listed virtualization and host-update domain, including relevant failure modes and rollout safety.
- Advanced proficiency in C, C++, Rust, Swift, or Go, with experience designing high-performance, secure, scalable, and reliable systems.
- End-to-end technical design ownership, including design documents, architecture tradeoffs, implementation, and review.
- Experience setting technical direction for an engineering group with or without formal management responsibility.
- Preferred experience with Linux kernel and system programming, KVM, userfaultfd, VFIO, kexec, kernel live patching, dirty-page tracking, device-state handling, host compatibility, and hardware-state device migration.
- Preferred experience with benchmarks and load tests, open-source virtualization projects, Kubernetes node lifecycle and fleet rollout orchestration, and building a team from zero.
