Job Description

Key Responsibilities

Analyze and categorize incoming Linux kernel vulnerabilities by validity, impact, and complexity; maintain high triage accuracy with minimal false negatives and improve backlog triage velocity, aligned with customer quality metrics.

Develop secure, high‑quality kernel patches for validated vulnerabilities; meet Time‑to‑Patch (TTP) SLAs for medium‑complexity issues and achieve high first‑pass CI/CD commit‑check acceptance.

Investigate kernel crashes, memory corruptions, and other low‑level issues; perform rigorous validation of findings.

Rigorously validate patches to prevent regressions and maintain sandbox stability across environments.

Document debugging approaches, findings, and fix rationales; share actionable insights with the team.

Review AI‑generated code fixes for correctness, safety, logical soundness, and security gaps; provide structured annotations (syntax, logic, security flaws) to improve model quality and maintain strong annotation depth/quality scores.

Partner with the Kernel Security Lead and POD team to meet delivery and quality goals; contribute to improvements in triage workflows, patch templates, and debugging best practices; collaborate with cross‑functional teams as needed (no direct customer ownership).

Skills & Experience Requirements

6–8 years of hands‑on engineering experience in Linux systems, kernel‑level development, or vulnerability research.

3–5 years of experience in C programming, debugging, low‑level memory analysis, or system‑level debugging.

Strong expertise in Linux kernel internals, including module development and patch creation.

Solid understanding of secure coding practices, vulnerability patterns, and exploit‑mitigation techniques.

Experience with debugging tools such as GDB, Ftrace, perf, or other kernel‑level diagnostic utilities.

Familiarity with kernel.org patch submission standards, including formatting, sign‑offs, and commit‑message conventions.

Ability to independently analyze complex technical issues and deliver high‑quality outputs within SLA timelines.

Strong written English skills, especially for technical documentation and patch annotation.
