Principal Analog Design Engineer - Austin, Texas, United States
Originally posted 17 December 2025 by the employer.
About the role
The Principal Analog Design Engineer will develop full-custom electronic transceiver components that interface directly with custom silicon photonics for an optical AI computing platform. You will own the full lifecycle of analog blocks from specification and architecture to tape-out-ready layout in deep-submicron CMOS processes.
What you'll do
- Design, simulate, and verify high-speed analog circuits, including high-swing drivers, transimpedance amplifiers, ADCs, DACs, and PLLs, in deep-submicron CMOS technologies. - Define block architecture and specifications based on system-level requirements. - Perform full-custom schematic capture, advanced analog simulations, and complete physical layout, including DRC/LVS, of critical analog blocks using Cadence Virtuoso. - Conduct layout floor planning, post-layout extraction, and simulations to validate performance against parasitic effects while ensuring signal integrity and power integrity. - Collaborate closely with the Photonics and Digital teams to optimize the electro-optic interface. - Collaborate with team members to prepare and conduct bench characterization and production tests.
What you'll need
- MS or PhD in Electrical Engineering. - 10+ years of professional experience in full-custom analog integrated circuit design, with 5+ years of dedicated experience in either GHz-speed RF or GHz-speed broadband analog design. - Demonstrated expert proficiency in the Cadence tool suite, specifically Virtuoso schematic, simulation, and custom layout. - Deep understanding of semiconductor device physics, linearity, noise analysis, and high-frequency circuit theory. - Proven track record of taking high-speed analog blocks from concept to mass production with successful tape-outs.
Nice to have
- Background in photonic transceivers or optical communication electronics. - Extensive design experience in TSMC technology nodes such as N5P, N3P, and N2P. - Experience designing high-speed data converters. - Experience designing low-jitter clocking circuits, including PLLs. - Proficiency in electromagnetic simulation tools such as EMX or HFSS. - Experience with frequency domain simulation in Spectre RF.
Skills: full-custom electronic transceiver components, silicon photonics, high-speed analog circuits, transimpedance amplifiers, ADCs, DACs, and PLLs, Cadence Virtuoso
