Product Description

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

Role and Team

We are looking for a Kernel Developer to join the KernelCare ELS Team. The team investigates upstream Linux kernel changes, backports fixes to supported enterprise kernels, builds distribution packages, and validates that patches are safe and reproducible. The role is centered on practical patching and building work. You will also use automation and agentic development tools to accelerate investigation while retaining engineering ownership of every result.

Responsibilities:

  • Investigating upstream security and bug fixes and identifying their dependencies.
  • Backporting Linux kernel patches to older RPM- and Debian-based distributions.
  • Resolving conflicts caused by differences between upstream and target kernel versions.
  • Building and rebuilding kernel source and binary packages in reproducible environments.
  • Validating patched kernels through focused tests, build checks, and regression analysis.
  • Improving patch preparation, build, and validation workflows with Python, Go, or Shell.
  • Using agentic development tools.
  • Documenting technical decisions and participating in code review with the kernel team.

Requirements

Must Have:

  • Strong C programming and Linux debugging skills.
  • Practical Linux kernel development, patching, or backporting experience.
  • Confident use of Git, GNU build tools, and standard Linux development utilities.
  • Experience building Linux kernels or distribution packages.
  • Automation experience with Python, Go, Shell, or a similar language.
  • Some experience with agentic or AI-assisted development and a clear approach to validating generated output.
  • English at an intermediate level or higher, both written and spoken.
  • Strong ownership, careful technical judgment, and readiness to explain trade-offs.

Nice to Have:

  • Experience with RPM/SRPM or Debian kernel packaging.
  • Security patching, CVE analysis, or extended lifecycle maintenance experience.
  • Familiarity with Docker, QEMU, Jenkins, or other CI systems.
  • Experience designing kernel tests or investigating core dumps and regressions.

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
