+ Define architecture and guide integration of low-level functionality for boot flows, memory management, and interrupt handling.

+ **Technical Leadership & Mentorship**

+ Provide technical guidance and coaching to engineers on kernel development best practices.

+ Influence design decisions and drive adoption of robust methodologies across the team.

+ **Platform Enablement & Validation**

+ Develop strategies for enabling base Linux configurations and diagnostics tools.

+ Define and implement validation frameworks, debug utilities, and observability features for post-silicon bring-up.

+ **Cross-Functional Collaboration**

+ Partner with silicon architects, firmware teams, and validation engineers to ensure feature readiness and compliance.

+ Engage with internal and partner stakeholders to improve design, security, and validation methodologies.

+ **Continuous Improvement & Innovation**

+ Drive continuous improvement of Linux kernel and driver architecture, ensuring scalability, maintainability, and long-term sustainability within Microsoft Cobalt platforms.

+ Apply a growth mindset to learn emerging technologies and adapt solutions in a dynamic environment.

+ **Deliver High-Quality Results**

+ Ensure timely delivery of drivers, tools, and validation collateral with exceptional quality and reliability.

+ Champion Microsoft values by fostering collaboration, inclusivity, and integrity in all interactions.

We will only achieve our mission if we live our culture. We start by becoming learners in all things—having a growth mindset. Then we apply that mindset to learning about our customers, being diverse and inclusive, working together as one, and—ultimately—making a difference in the world.
