KernelCare provides automated live patching for Linux kernels without requiring reboots. Our 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).
