Job Title

Senior Analog/Mixed-Signal IC Design Engineer — Acacia

Role Summary

Senior engineer on the Mixed-Signal IC design team responsible for architecture, design, layout, measurement and productization of ultra-deep-submicron CMOS transceivers for optical communications.

Work on high-speed and high-accuracy analog/mixed-signal building blocks that integrate into ASICs; collaborate with digital/DSP, package, system and module teams. This is a hybrid role with three days per week at the San Jose, CA office.

Experience Level

Senior. Posting specifies degree-based experience guidance (see Education Requirements) or equivalent practical experience.

Responsibilities

Key responsibilities include design leadership, hands-on circuit development, verification, and cross-team coordination.

  • Architect, design, layout, measure and productize ultra-deep-submicron CMOS ICs for high-speed optical transceivers.
  • Lead large design blocks on complex chips; define and track deliverables and schedules.
  • Mentor and review work of other engineers; perform peer reviews and enforce design methodology from concept through production.
  • Collaborate with packaging and hardware teams to meet signal integrity and power integrity requirements.
  • Develop high-speed analog/mixed-signal circuits and support their integration into ASICs and modules.

Requirements

Must-have technical skills and experience relevant to the role.

Must-have:
  • Design, simulation and measurement experience for high-speed ICs, including at least three of the following domains: high-speed serial links (SERDES), data converters, voltage regulators, output drivers, phase-locked loops (PLLs), clock transmission/propagation, operational amplifiers, programmable gain amplifiers, and equalization.
  • Hands-on experience with analog/mixed-signal verification, simulation and lab measurement techniques.
  • Experience delivering designs that move from concept into production.
Nice-to-have:
  • Experience with electrical transceiver applications (backplane and cable communications).
  • Experience with FinFET technologies and high-frequency/custom transistor layout.
  • Passive component and transmission-line layout experience (inductors, transformers, transmission-lines).
  • Floorplanning experience (power/ground, digital/analog routing) and design-for-manufacturability practices.
  • ESD laboratory practices and methodology.
  • Familiarity with Cadence Virtuoso, Spectre/APS/SpectreX, MATLAB, EMX and mixed-signal (AMS) simulation flows.

Education Requirements

Degree and experience options stated in the posting: B.S. in Electrical Engineering (BSEE) with ~12+ years of experience, or M.S. with ~8+ years, or Ph.D. with ~5+ years, or equivalent practical experience. Fields referenced imply electrical/electronic engineering or closely related technical disciplines. Certification requirements are not specified.
