• Compile and rebuild kernel source and binary packages utilizing reproducible build environments for both RPM and Debian ecosystems.

• Validate patched kernels through build tests, runtime evaluations, and regression analyses.

• Improve internal processes for patch preparation, build automation, and validation pipelines using Python, Go, and Shell scripting.

• Utilize agentic/AI-assisted development tools while meticulously verifying the generated outputs.

• Document technical decisions made during the development process.

• Engage in code reviews to ensure quality and standards.

• Communicate effectively with team members across various time zones.
