Principal Mixed Signal Engineer, Texas Institute for Electronics

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 performance across heterogeneous integration stacks-accounting for signal integrity, power delivery, crosstalk, and thermal effects unique to 3DHI.
• Lead silicon bring-up, bench characterization, and production testing of high-speed I/O and mixed-signal circuits-developing test methodologies, ATE programs, and yield-improvement strategies from prototype through volume production.
• Engage with industry partners and standards bodies (UCIe Consortium) to influence specification development and ensure TIE's physical-layer implementations remain standards-aligned.
• Mentor internal design teams on mixed-signal design methodologies, high-speed measurement techniques, and production test best practices for multi-die systems.
• Translate mixed-signal design innovations into IP roadmaps and reference designs, driving alignment between research, productization, and customer enablement for UCIe-based chiplet ecosystems.
• Required Qualifications
• M.S. in Electrical Engineering with emphasis on analog/mixed-signal or high-speed circuit design (or equivalent practical experience).
• 12+ years of experience in mixed-signal or high-speed I/O circuit design for SoC/ASIC, with direct involvement in SerDes, UCIe, or comparable die-to-die/chip-to-chip interface IP.
• Deep expertise in high-speed transceiver design-including TX/RX front-ends,
