- migrating to newer distributions,
- maintaining and improving the security posture,
- patching vulnerabilities
We work closely with our Product Management team to align our security features with NIST Cybersecurity Framework. We also work closely with PSIRT and Legal/licensing to ensure that we deliver safe updates. We also work closely with our build teams to expand and improve the Linux OS availability to all teams through our Base OS repo feeds into the Common OS build pipeline. Our teams charters include CVE Patching Management, Blackduck security and licensing remediation, NCI & Workflow Security Features, and OS/Kernel Development.
At Nutanix, we foster a mutually respectful workplace, value diversity, and offer growth opportunities.Our core values: Hungry, Humble, Honest, with a Heart. Join us in creating innovative solutions using Linux!

Your Role
This position is in the Linux Development group where team members work on the full lifecycle. The team looks at incoming Linux user-space and kernel issues, and finds solutions which may be a package update, a driver update, a code change, or a larger solution to address multiple similar issues with the product, such as memory issue, FIPS certifications, etc. You should have worked on some complex problems related to this area and be able to lead architectural discussions and create detailed design documentation.
The team is also responsible for updating the Linux distro to include newer RPMs, replacement packages for obsolete packages, or to newer distro versions. Also, from time to time we may migrate the Linux distro to different vendors. This includes bringing upstream Linux LTS kernels into our OS. These are cross-team efforts where this team takes a leading position in driving the changes across teams. These distro updates include STIG compliance solutions as well Blackduck licensing.
What You Will Bring
- Experience and good working knowledge of the Linux user and kernel spaces with 8 or more years of experience in this field and the ability to lead architectural discussions.
- Ability to work in a cross-functional team environment to deliver Linux user space and kernel solutions that meet multiple requirements.
- At least a BS in Computer Science (not Computer Engineering), MS preferred.
Linux Proficiency
- A deep understanding of Linux operating systems, including system administration, troubleshooting, and performance optimization.
- Experience with multiple Linux distros, e.g. CentOS, Red Hat, Rocky, etc.
- Familiarity with Linux in a hyperconverged infrastructure or virtualization space would be a plus, e.g. kvm, VMware ESXi, etc.
- Open-source kernel contributions would be a plus.
- Solid understanding of the following:
- Memory allocation, like slab allocator, malloc etc.
- Process scheduling, prioritization, SW page table handling cgroup concepts
- Kernel debugging, crash analysis, tracing, etc.
- Threading
- Driver integration
