Senior Kernel / Virtualization development Engineer

Join us to build the core of a next-generation virtualization platform. You'll work at the Linux kernel and VMM boundary, developing low-level virtualization technologies similar to KVM, QEMU, and Firecracker.

Responsibilities

Design and develop hypervisor & VMM components (vCPU, memory, device model, KVM API).

Develop Linux kernel code, drivers, and kernel modules.

Build lightweight, secure, high-performance microVM infrastructure.

Implement and optimize virtio devices and guest-host communication.

Profile and improve boot time, memory, and I/O performance.

Debug complex guest/host/kernel issues using low-level tooling.

Drive code reviews, technical direction, and systems architecture.

Requirements

7+ years of low-level systems software development.

Expert in C and strong Rust.

Deep Linux kernel and OS internals knowledge.

Hands-on experience with KVM, QEMU, Firecracker, or similar hypervisors.

Strong understanding of virtualization technologies (VT-x/AMD-V), virtio, and kernel debugging.

Nice to Have

Linux kernel or virtualization open-source contributions.

Experience with serverless, container runtimes, or confidential computing (TDX / SEV-SNP).

ARM64 virtualization, performance engineering, or security research.
