• Participate in code reviews and technical design discussions.
• Pick up new subsystems and device technologies as team priorities evolve.

• Strong understanding of operating systems internals and systems programming.
• Demonstrated ability to work effectively across different layers of a software stack (e.g., kernel, user-space, framework, application).
