Staff Infrastructure Engineer Virtualization

About TensorWave

Our mission is simple: deliver seamless secure reliable and resilient AI compute at scale. Weve built a versatile cloud platform that eliminates infrastructure barriers empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas not infrastructure.

About the Role

We are building large-scale high-performance infrastructure to power next-generation AI workloads. Our platform operates across multiple data centers and supports GPU-intensive environments with demanding requirements around performance isolation and scalability.

We are looking for a Staff Infrastructure Engineer to lead the design and evolution of our virtualization platform. This role will own how we build scale and operate hypervisor infrastructure as we transition from traditional virtualization platforms toward a more flexible CSP-aligned architecture based on KVM/QEMU and modern Linux primitives.

This is a highly technical hands-on role focused on solving complex systems problems at scale.

What Youll Do

• Design and implement a scalable virtualization platform capable of supporting high-density compute and GPU workloads

• Lead the evolution from existing platforms (e.g. Proxmox) toward KVM/QEMU-based architectures

• Define standards for VM lifecycle management (provisioning scheduling migration) performance isolation and resource allocation failure domains and resilience strategies

• Optimize virtualization for high-performance workloads including NUMA alignment CPU pinning and scheduling PCIe topology awareness GPU passthrough and device assignment

• Partner closely with networking and storage teams to integrate high-throughput networking (e.g. SR-IOV RDMA) distributed and local storage systems

• Build and improve automation for hypervisor deployment and configuration image pipelines cluster scaling and lifecycle management

• Troubleshoot deep system-level performance issues across compute memory storage and network layers

• Contribute to long-term platform architecture and infrastructure strategy

Who You Are

Required Qualifications

• 7 years of experience in infrastructure systems engineering or platform engineering

• Deep experience with Linux-based virtualization including:

  • KVM/QEMU

  • libvirt or similar tooling

• Strong understanding of:

  • CPU scheduling and NUMA architectures

  • Memory management and performance tuning

  • Storage I/O paths and performance characteristics

• Experience designing and operating virtualization platforms at scale (hundreds hosts)

• Solid networking fundamentals including:

  • Linux networking (bridges bonding VLANs)

  • High-performance networking concepts

• Experience with infrastructure automation (e.g. Ansible Terraform or similar)

• Strong troubleshooting skills across distributed systems

Preferred Qualifications

• Experience in cloud or CSP environments (public or private)

• Familiarity with:

  • GPU workloads and passthrough (VFIO)

  • SR-IOV and advanced NIC features

• Experience integrating virtualization with:

  • Kubernetes platforms

  • Bare metal provisioning systems (e.g. MAAS)

• Exposure to distributed storage systems (e.g. Ceph Weka or similar)

• Experience working in high-performance or low-latency environments
