Purpose 

The purpose of the Principal Mixed Signals Engineer is to develop next-generation digital subsystems and compute fabrics for 2.5D/3D microsystems, enabling scalable, high-bandwidth integration across AI, HPC, and wireless acceleration platforms. This includes defining architecture specifications, collaborating with teams to optimize performance, and engaging with semiconductor industry partners to shape ecosystem directions.

Responsibilities 

• Design and develop high-speed mixed-signal I/O circuits for UCIe 2.5D and 3.0D die-to-die interfaces in 2.5D/3D microsystems—enabling robust, low-latency chiplet interconnect across AI, HPC, and defense platforms.
• Architect and optimize SerDes, clock/data recovery (CDR), equalization, and transceiver circuits for high-speed die-to-die and chip-to-chip links, including UCIe, PCIe physical layers.
• Collaborate with packaging, EDA, and system modeling teams to co-optimize mixed-signal I/O pe
