Principal Design Engineer

Job Title

Principal Design Engineer

Role Summary

Responsible for analog circuit design focused on high-speed SerDes and memory interface circuits. Works within an ASIC design team to develop I/O, PLLs, clocking, and datapath circuitry for high-performance interfaces.

Role includes circuit design, verification, collaboration on signal and power integrity, and supporting silicon bring-up and reliability efforts.

Experience Level

Senior - typically requires 8+ years of relevant experience in analog, I/O, SerDes, or memory-interface design.

Responsibilities

Key responsibilities include:

• Design and implement high-speed SerDes and memory interface circuits (I/O, PLLs, clocking, datapaths).
• Architect and optimize interfaces such as PCIe and DDR/LPDDR/GDDR PHYs and related datapaths.
• Perform circuit-level verification, simulation, and characterization addressing SI/PI and reliability.
• Collaborate with digital, package, and board teams on SI/PI and ESD requirements.
• Debug silicon failures, analyze measurements, and propose corrective actions.
• Document design decisions and present technical results to stakeholders.

Requirements

Must-have and preferred qualifications:

• Must-have: Deep understanding of high-speed SerDes and memory interface circuits including I/O, PLLs, clocking, and datapaths.
• Must-have: Hands-on experience with PCIe Gen3/4/5/6 and DDRx/LPDDR/GDDR memory interface circuits.
• Must-have: Strong analog and I/O design fundamentals; experience with ESD, reliability, signal integrity (SI) and power integrity (PI).
• Must-have: Excellent written and verbal communication and strong problem-solving skills.
• Nice-to-have: Prior experience on advanced process nodes such as 16nm, 12nm, 10nm or 7nm.

Education Requirements

Bachelor's or Master's degree in engineering (BE, BTech, ME, MTech) or MS in a related technical field, or equivalent practical experience.
