Analog/mixed-signal IC Design Engineer - Acacia
Cisco SystemsJob Title
Analog/mixed-signal IC Design Engineer - Acacia
Role Summary
Join the Acacia mixed-signal IC design team to architect, design, layout, measure and productize ultra-deep-submicron CMOS analog and mixed-signal blocks used in high-speed optical transceivers (100G–1.6T+). The role focuses on high-speed AMS circuit development and cross-functional integration with digital/DSP, package, and module teams.
Work is hybrid with an office presence in San Jose, CA three days per week.
Experience Level
Senior-level. Candidates are expected to have substantial prior experience designing high-speed analog/mixed-signal integrated circuits; see Education Requirements for degree-specific minimums.
Responsibilities
Key responsibilities include ownership of complex mixed-signal blocks from concept through production and collaboration across engineering disciplines.
- Architect, design, simulate, lay out, and validate high-speed analog and mixed-signal IC blocks in advanced CMOS technologies.
- Lead design efforts for large blocks, mentor junior engineers, track deliverables, and participate in design reviews.
- Develop and apply robust design methodologies to ensure manufacturability and productization.
- Collaborate with digital/DSP, system, packaging, and hardware teams to meet signal and power integrity requirements.
- Plan and support laboratory validation, measurement, and characterization of prototypes.
Requirements
Technical must-have skills and experience; candidates should meet core AMS design criteria and practical tool usage.
- Must-have: Significant experience in high-speed analog/mixed-signal IC design and measurement, including practical experience across multiple of the areas listed below.
- Experience in design, simulation and measurement of high-speed ICs in at least three of these areas:
- High-speed serial links (SERDES, serializers/deserializers, data converters)
- High-performance output drivers
- Phase-locked loops (PLLs) and clock transmission/propagation
- Op amps and programmable gain amplifiers
- Equalization techniques and link modeling for system simulations
- Nice-to-have: Experience with FinFET/GAA processes, high-frequency layout and floorplanning, DFM/characterization over PVT, electromigration and IR-drop analysis, ESD practices, and laboratory test setups.
- Familiarity with industry tools and flows (Cadence Virtuoso, Spectre/SpectreX/APS, Calibre, EMX, AMS simulation flows, MATLAB) is desirable.
Education Requirements
Degree and experience minimums specified by the employer: Bachelor's degree with 8+ years of related experience, Master's degree with 6+ years, or PhD with 3+ years of related experience. No specific fields of study or certifications were listed.
