Job responsibilities

Design the migration and refactoring strategy for core orchestrator services (vbin, LSS, LDM, VMAP, RS, Backup) and in-flight features to support ARM64 infrastructure.

Design NUMA memory allocation models, cross-socket optimization strategies, and NUMA topology for high-core-density ARM hardware.

Establish technical blueprints and strategies for Live, Warm, and Cold VM hypervisor migrations on ARM architectures.

Design nested virtualization integration and hypervisor execution models.

Drive joint architectural decisions and embedded design reviews directly with engineering leads across teams.
