Job description

Description

Seeking a Senior Software Engineer to join our Platform Systems & Virtualization Team responsible for core hypervisor infrastructure, virtual device emulation, and low-level firmware integration. In this role, you will work directly at the intersection of firmware and the operating system, developing QEMU device models, maintaining custom BIOS/firmware integrations ( SeaBIOS), pushing upstream contributions, and optimizing core Linux kernel subsystems.

Requirements

• Bachelor of Science in Computer Science, Computer Engineering, or a related field.
• Minimum 4 years of experience in low-level systems and Linux kernel development
• Strong proficiency in C for low-level systems programming
• Deep knowledge of Linux kernel internals, specifically memory management (subsystems, page allocation, MMU).
• Hands-on development experience with QEMU (device emulation and platform models).
• Experience creating, patching, or customizing BIOS/firmware versions for QEMU (SeaBIOS, EDK2/UEFI, Coreboot, or U-Boot). Direct SeaBIOS experience is preferred, but custom BIOS development within QEMU environments is accepted.
• Strong understanding of PCI / PCIe specifications, bus configuration, ACPI tables, and device drivers.
• Practical experience using eBPF for kernel tracing, profiling, and performance diagnostics.
• Nice to have:
• Track record of preparing code reviews and submitting upstream patches to open-source projects (e.g., QEMU, SeaBIOS, EDK2, Linux Kernel).
• Experience with Rust in systems or kernel context.
• Background in GPU drivers or virtualized graphics stacks (vfio, vGPU).
• Scripting in Python for test automation and debugging harnesses

Job responsibilities

• Architect, implement, and maintain virtualization components across QEMU, SeaBIOS, and the Linux kernel.
• Develop, debug, and optimize kernel memory management and virtual device pipelines.
• Implement and configure virtual and pass-through PCI / PCIe device models in QEMU.
• Maintain low-level SeaBIOS firmware code, ACPI table generation, interrupt handling, and system bootstrap routines.
• Profile platform latencies, hypervisor-to-guest performance, and memory footprints using eBPF.
• Deliver robust, upstream-quality patches and root-cause complex platform-level issues.
