Senior Software Engineer – Hypervisor - OS

SUMERU TECHNOLOGY SDN.BHD.; George Town; On-site; MYR 120,000 - 180,000; Full time

Job summary

SUMERU TECHNOLOGY SDN.BHD. in Penang, Malaysia invites an experienced kernel and OS developer to join our systems engineering team.

You will work across Linux-based kernels, RTOS, and potential exotic kernels, pushing the boundaries of memory management, scheduling, and I/O subsystems. We value hands-on virtualization with KVM, Xen, and related hypervisors, plus low-level programming in C, Assembly, and optionally C++ or Rust.

Qualifications

• Deep understanding of OS internals (memory management, scheduling, I/O subsystems, and interrupt handling).
• Experience with Linux, RTOS, Fuchsia or proprietary kernels.
• Hands-on experience with hypervisor technologies (KVM, Xen, ACRN, Hyper-V, or VMware ESXi) and hardware virtualization extensions.
• Mastery of C and Assembly (x86 or ARM). Proficiency in C++ or Rust is a significant plus.
• Proven ability to write and debug character/block device drivers and handle DMA and PCIe interfaces.
• Experience with Agile Methodology, Sprint-based development, Jira or Linear.
• CI/CD: Jenkins, GitLab CI, GitHub Actions; automated pipelines and regression tests.
• DevOps mindset: IaC and containerization (Docker/Kubernetes) as it relates to testing OS environments.
• Collaborative Version Control: Git and Gerrit, branching, rebasing, peer code review.

Job description

Jora Malaysia will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

Kernel & OS Development:

Deep understanding of OS internals (memory management, scheduling, I/O subsystems, and interrupt handling). Experience with Linux, RTOS, Fuchsia or proprietary kernels.

Virtualization Expertise:

Hands-on experience with hypervisor technologies (KVM, Xen, ACRN, Hyper-V, or VMware ESXi) and hardware virtualization extensions (Intel VT-x, AMD-V, or ARM Virtualization Extensions).

Low-Level Programming:

Mastery of Cand Assembly(x86 or ARM). Proficiency in C++ or Rust is a significant plus.

Device Drivers:

Proven ability to write and debug character/block device drivers and handle DMA and PCIe interfaces.

Team Cooperation & Workflow (Agile/DevOps)

As a systems engineer, you don't work in a vacuum. We value engineers who bridge the gap between "bare metal" and modern software delivery:

Agile Methodology:

Experience working in a Sprint-based environment. You should be comfortable with iterative development, participating in daily stand-ups, and using tools like Jira or Linear to track progress.

CI/CD Integration:

Familiarity with integrating low-level code into automated pipelines (e.g., Jenkins, GitLab CI, or GitHub Actions). You understand that "it works on my board" isn't enough until it passes the automated regression suite.

DevOps Mindset:

Experience with Infrastructure as Code (IaC) and ontainerization

(Docker/Kubernetes) as it relates to testing OS environments or simulating hardware.

Collaborative Version Control:

Advanced knowledge of Git and Gerrit, specifically regarding complex branching, rebasing, and rigorous Peer Code Review processes.
