Senior Kernel & Qemu Engineer

Hitachi, Ltd.; Wrocław; Hybrid; PLN 180.000 - 260.000; Vollzeit

Zusammenfassung

GlobalLogic is seeking a Senior Software Engineer to join our Platform Systems & Virtualization team, focusing on core hypervisor infrastructure, device emulation, and low-level firmware integration. You will work at the intersection of firmware and OS, developing QEMU device models and SeaBIOS integrations.

You will contribute to kernel memory management optimizations, write upstream-quality patches, and collaborate across teams to deliver robust virtualization components for Linux environments.

Qualifikationen

• 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, 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.

Aufgaben

• 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.
