## Description

**TuxCare** offers a comprehensive portfolio of security solutions for Linux and open-source software designed for enterprise organizations. With TuxCare, companies can automate live vulnerability patching, minimize downtime, ensure security and compliance, and rely on a team with deep expertise in Linux security. The solutions cover the most popular Linux distributions, end-of-life systems, programming languages, and more. Learn more at [tuxcare.com](https://tuxcare.com/).

[KernelCare](https://tuxcare.com/enterprise-live-patching-services/kernelcare-enterprise/) provides automated live patching for Linux kernels without requiring reboots. Our [Endless Lifecycle Support](https://tuxcare.com/endless-lifecycle-support/) products keep end-of-life Linux distributions secure by backporting important security and bug fixes to older software versions used by enterprise customers.

**We are looking for a Senior Kernel Support Engineer to join our small, experienced team at KernelCare.** An AI agent handles first-line triage, allowing our engineers to focus on complex technical cases that require their expertise. The team also develops and maintains tools and AI-powered agents to automate support processes and improve efficiency.

**What you will do**

-   Analyze crashes, hangs and reboots related to live patching: oops and panic logs, vmcore with the crash tool, KASAN reports. Decide if the live patch caused it or not, and say so to the customer.
-   Investigate problems during patching: apply failures, stuck transitions, unknown symbols, freeze conflicts with backup tools.
-   Investigate missing patches and new kernel or distro support requests, and work with the patch team to add support.
-   Answer deep CVE questions: check the patch sources, not only the docs.
-   Find the root cause, give the patch team a clear report, and follow it to the fix.
-   Be the named engineer for an enterprise customer during a Sev 1: their hosts are down, you own the case until it is closed.
-   Help during big CVE events.
-   On-call for Sev 1 with the team (24/7 is a contract obligation; we share it).

## Requirements

**Must haves**

-   Strong knowledge of Linux kernel internals, including memory management (MM), VFS, networking, scheduling, and locking mechanisms.

-   Hands-on experience with Linux kernel crash analysis, including the use of debugging tools such as crash, vmcore analysis, and kernel oops decoding.
-   Good C programming skills, with the ability to read and analyze Linux kernel code and patches to identify root causes of issues.
-   Experience working with vendor security advisories (RHSA, USN, DSA) and kernel changelogs, including Git history.
-   Experience handling critical production incidents and technical escalations for enterprise customers, with the ability to communicate complex technical issues and investigation progress clearly.
-   Excellent written English communication skills, with the ability to explain technical findings clearly and concisely.

**Nice-to-haves**

-   Familiarity with Linux live patching technologies (kpatch, livepatch, ksplice).
-   Experience with virtualization and container technologies, including Proxmox, KVM, OpenVZ, LVE, and cgroups.
-   Experience using Python and shell scripting for automation, troubleshooting, and log analysis.
-   Familiarity with AI/LLM tools for debugging and technical investigations.
-   Experience in Site Reliability Engineering (SRE).

## Benefits

**What's in it for you?**

-   A focus on professional development.
-   Interesting and challenging projects.
-   Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide.
-   Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
-   Compensation for private medical insurance.
-   Co-working and gym/sports reimbursement.
-   Budget for education.
-   The opportunity to receive a reward for the most innovative idea that the company can patent.
