About the company and the project:

An international company specializing in the development of modern operating systems for hosting providers is looking for a Kernel developer to join its team!

The company's products are used by thousands of companies around the world, including Dell, GoDaddy, IBM, Zoom and many others. You will be working on the fastest growing product providing automatic kernel security updates without rebooting for the most popular Linux distributions.

You are offered a job in a completely remote company with a flexible schedule and the ability to plan your day and work from anywhere in the world.

Your tasks on the position:

Research & Analysis: Investigate upstream security (CVE) and bug fixes; analyze patch dependencies and impact on legacy kernels
Backporting: Manually backport Linux kernel patches to older kernel versions used in RPM-based and Debian-based distributions
Conflict Resolution: Resolve merge conflicts between upstream changes and target kernel codebases
Kernel Packaging: Build and rebuild kernel source and binary packages using reproducible build environments for RPM and Debian ecosystems
Validation & Testing: Validate patched kernels through build tests, runtime tests, and regression analysis to ensure stability
Tooling & Automation: Enhance internal workflows (patch preparation, build automation, validation pipelines) using Python, Go, and Shell scripting
AI Integration: Leverage agentic/AI-assisted development tools to accelerate tasks, while rigorously verifying every generated output
Documentation & Collaboration: Document technical decisions, participate in code reviews, and communicate clearly with team members across time zones

Requirements:

Strong C proficiency and hands-on Linux debugging skills
Proven commercial experience in Linux kernel development—specifically patching, backporting, or debugging
Solid experience with Git, GNU build tools (make, autotools), and standard Linux developer utilities
Experience building Linux kernels or distribution packages from source
Scripting and automation skills: Python, Go, or Shell
Practical exposure to AI-assisted development tools (e.g., Copilot, Codeium, or similar), with a disciplined approach to code verification
English: Intermediate or higher (B1+), both written and spoken—you’ll be working in an international team and communicating in English daily
Strong ownership mindset, balanced technical judgment, and ability to articulate trade-offs

Will be an advantage:

Experience with RPM/SRPM or Debian kernel packaging
Familiarity with security patching, CVE analysis, and extended lifecycle maintenance
Working knowledge of Docker, QEMU, Jenkins, or other CI systems
Experience designing kernel validation tests, analyzing core dumps, and investigating regressions

Benefits:

100% remote work with flexible hours — work from anywhere in the world (focus on LATAM-friendly time zones)
24 paid vacation days + 10 national holidays + unlimited sick leave
Private medical insurance compensation
Coworking space and sports/fitness reimbursement
Professional development budget — conferences, courses, certifications
Reward program for patentable ideas
A collaborative, non-corporate environment with a strong engineering culture
