Director, SI/PI

About the role

We are seeking a Director to drive Signal Integrity, Power Integrity of our first generation MPU. It involves all aspects for SI/PI from silicon to system. This role will be performed onsite from one of our offices in Santa Clara, CA or Boston, MA.

Impact: We are tackling a fundamental challenge at the infrastructure layer: unlocking greater AI capability while dramatically improving efficiency. The work we do here compounds across state-of-the-art AI models, systems, and real-world applications. Timing: Joining now means real ownership of the company and meaningful influence over product direction and execution. You’ll work from first principles, move quickly from insight to execution, and see your contributions directly reflected in what we build. Culture: You’ll work alongside a group of people who care deeply about rigor, clarity, and impact. We value thoughtful disagreement, fast learning, and intellectual fearlessness. This is a place where strong ideas shine, curiosity is encouraged, and growth is a daily practice.

Responsibilities

• Responsible for technical solution development for Signal Integrity and Power Integrity.
• Drive system-level SI/PI architecture, design guidelines, and layout recommendations.
• Perform end-to-end channel simulations for high-speed serial interfaces and memory subsystems.
• Lead SI/PI analysis and optimization of DDR5, LPDDR5, LPDDR6, and other high-performance memory interfaces.
• Correlate simulations with lab measurements and drive root-cause analysis of signal and power integrity issues.
• Collaborate with silicon, package, PCB, architecture, and manufacturing teams to resolve complex SI/PI challenges.
• Evaluate future package and PCB technologies to support next-generation FPGA and adaptive computing products.

Qualifications

• MS or PhD in Electrical Engineering
• 5+ years of direct industry experience

Skills

• Excellent analytical and problem-solving skills with strong attention to detail.
• Proven ability to independently drive technical decisions and influence engineering direction.
• Strong communication and cross-functional collaboration skills.
• Hands-on experience performing lab measurements and correlating hardware results to simulation models.
• Deep expertise in Signal Integrity with working knowledge of Power Integrity concepts and methodologies.
• Experience with DDR, LPDDR, or other high-performance memory interfaces.
• Experience with FPGA, adaptive computing, ASIC, networking, datacenter, or high-performance computing platforms.
• Experience with PCB, package, and IC-level power delivery networks.
