Linux Kernel Security Engineer

Summary: The Linux Kernel Security Engineer role involves managing the triage and remediation of kernel vulnerabilities, developing and validating patches, and ensuring the stability and quality of patch delivery. The position requires collaboration with customers and mentoring of engineers while leveraging AI for patch evaluation. The role is based in London with a hybrid working arrangement. It is a 12-month B2B contract position.

Key Responsibilities:

• Perform systematic triage classification and prioritization of incoming Kernel vulnerabilities
• Ensure high triage accuracy with minimal false negatives in alignment with customer-defined quality metrics
• Develop, refine, and validate high-quality Linux Kernel patches for identified vulnerabilities
• Ensure fast Time-to-Patch (TTP) for medium-complexity issues meeting defined SLAs
• Ensure first-pass acceptance of patches by adhering to automated CI/CD checks and upstream kernel.org submission standards
• Conduct deep debugging and validation to ensure patches do not introduce regressions or instability
• Own the end-to-end technical quality of patch delivery including regression rate reduction
• Review AI-generated patches and provide detailed high-quality annotations on syntax, logic, and security flaws
• Deliver structured feedback to improve AI model performance, patch correctness, and security relevance
• Lead a technical POD focused on Kernel vulnerability analysis and remediation
• Collaborate directly with customer stakeholders to review results, discuss blockers, and meet quality velocity targets
• Mentor engineers to improve fix rate, Kernel debugging depth, and patch quality

Key Skills:

• Extensive years of total experience including 5 years managing technical teams and handling customer-facing interactions
• 5 years of professional experience in C debugging, Kernel debugging, or system-level problem diagnosis
• 5 years of hands-on Linux Kernel development, patch creation, or subsystem level contributions
• Strong understanding of system security, secure coding standards, vulnerability analysis, and patch-hardening techniques
• Proven experience with kernel.org patch submission, commit message standards, and upstream workflows is a strong plus
• Ability to independently analyze complex technical issues and drive them to closure within defined SLAs (Triage Velocity, Fix Rate, TTP)
• Excellent communication skills in English, including the ability to explain technical decisions clearly to customers and internal teams
