Analog/mixed-signal IC Design Engineer - Acacia (Hybrid)

Job Title

Analog/mixed-signal IC Design Engineer - Acacia (Hybrid)

Role Summary

Member of the Acacia mixed-signal IC design team developing high-speed analog circuits for optical transceivers (100G–1.6T+). The role focuses on architecting, designing, laying out, measuring and productizing ultra-deep-submicron CMOS analog/mixed-signal blocks and delivering them into production.

This is a hybrid role based in San Jose, CA (three days per week on-site) working closely with digital/DSP, package, system and module teams.

Experience Level

Senior — typically requires 8+ years of relevant industry experience.

Responsibilities

Primary responsibilities for the role include:

• Architect, design, layout, and validate high-speed analog/mixed-signal IC blocks for optical transceivers.
• Lead design efforts for large/complex blocks, track schedule and deliverables, and mentor junior engineers.
• Perform peer reviews and define robust design methodology from concept through production.
• Collaborate with digital/DSP, package, system and module teams to meet signal and power integrity targets.
• Develop test plans, participate in laboratory validation and characterization, and resolve issues found in silicon.
• Support design-for-manufacturability work including PVT characterization, IR drop and electromigration analysis.

Requirements

Must-have technical skills and experience:

• Proven experience designing, simulating, and measuring high-speed ICs. Must demonstrate experience in at least three of the areas listed below:
• High-speed serial links (serializers, deserializers, data converters)
• Modeling requirements for system link simulations
• High-performance output drivers
• High-performance phase-locked loops (PLLs)
• Efficient clock transmission and propagation
• Op amps and programmable gain amplifiers (PGAs)
• Equalization techniques
• Experience collaborating with packaging and hardware teams to meet signal and power integrity specifications.
• Demonstrated ability to take complex analog blocks from concept through production including measurement and silicon bring-up.

Nice-to-have:

• Experience with electrical transceiver applications (backplane and cable communications).
• Experience with FinFET and GAA technologies.
• High-frequency layout experience, including floorplanning and passive components (inductors, transformers, transmission lines).
• Experience with lab validation practices including ESD methodology and custom test setups.
• Familiarity with design and simulation tools such as Cadence Virtuoso, Spectre/APS/SpectreX, Virtuoso/Calibre layout validation, EMX, AMS simulations, and MATLAB.

Education Requirements

Minimum qualification structure: Bachelor's degree plus 8 years related experience, or Master’s degree plus 6 years related experience, or PhD plus 3 years related experience. The posting does not specify required fields of study or certifications.
