Experience Level

Senior. No specific years of experience are stated.

Responsibilities

Own and deliver system-level architecture and roadmaps; ensure coherent integration across hardware, firmware and software.

• Define and maintain the system architecture roadmap, balancing performance, power, and scalability.
• Lead system-level design from concept through production; coordinate with chip design, mechanical, and manufacturing teams.
• Specify system interfaces, power delivery networks, interconnects, and control subsystems.
• Guide board and platform design to support early bring-up and validation.
• Partner with software and firmware leads to ensure seamless integration and system-level performance.
• Evaluate emerging components and technologies to inform architectural decisions.
• Act as a technical mentor and enforce design discipline and documentation standards.
• Represent system architecture in technical reviews, partner discussions, and customer engagements.
