Job 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 sub-micron CMOS analog and mixed-signal circuits for high-speed optical transceivers (100G–1.6T+).

The role works closely with digital/DSP, system, package and module teams to deliver integrated transceiver ASIC blocks used in data center and telecom networks. This is a hybrid role with an expected in-office cadence of three days per week in San Jose, CA.

Experience Level

Senior β€” experience guidance: B.S. + 8 years, M.S. + 6 years, or Ph.D. + 3 years of related industry experience.

Responsibilities

Primary responsibilities include leading a large block on complex mixed-signal chips and driving designs from concept through production.

  • Architect, design, simulate, lay out, and verify high-speed analog/mixed-signal IC blocks.
  • Lead design efforts for a major block, track deliverables, and mentor junior engineers.
  • Participate in peer reviews and enforce solid design methodology and documentation.
  • Collaborate with digital/DSP, system, package and module teams to meet system-level signal and power integrity requirements.
  • Define and support lab validation, characterization and production bring-up activities.

Requirements

Must-have technical skills and experience. Candidates should meet the minimum experience guidance in the Education Requirements section.

  • Proven experience designing, simulating and measuring high-speed ICs; experience must cover at least three of the following areas: high-speed serial links (SERDES, ADC/DAC), system link modeling, high-performance output drivers, phase-locked loops (PLLs), clock transmission/propagation, opamps/PGA, and equalization techniques.
  • Deep understanding of signal and power integrity and techniques to meet system specs in mixed-signal ASICs.
  • Experience producing silicon from concept to production qualification, including corner/PVT analysis and characterization.
  • Strong problem-solving, documentation and cross-functional collaboration skills; ability to lead design reviews and mentor team members.
  • Nice-to-have: experience with electrical transceiver applications (backplane/cable), FinFET/GAA process nodes, high-frequency layout and floorplanning, DFM and reliability analyses (EM, self-heating, IR drop), lab validation and ESD practices, and tools such as Cadence Virtuoso, Spectre/APS/SpectreX, Calibre and Matlab.

Education Requirements

Degree and equivalent experience requirement: Bachelors + 8 years related experience, or Masters + 6 years related experience, or PhD + 3 years related experience. No specific field of study was mandated in the posting; equivalent practical experience is acceptable per the degree-equivalent language above.

Additional Information

Role is based in San Jose, CA with a hybrid schedule (approximately three days per week in-office). Compensation ranges were provided for U.S. and Canada locations.
