Job Title

Analog/Mixed-Signal IC Design Engineer - Acacia (Hybrid)

Role Summary

Member of the Mixed Signal Design team developing high-speed, high-accuracy analog and mixed-signal ICs for optical transceivers (100G–1.6T+). The role covers architecture, circuit design, layout, lab validation and productization for ultra-deep sub-micron CMOS chips.

This is a hybrid role with an expectation of three days per week on-site in San Jose, CA, collaborating with digital/DSP, system, package and module teams.

Experience Level

Level: Senior. Typical experience guidance: Bachelor's + 8 years, Master's + 6 years, or PhD + 3 years of relevant experience.

Responsibilities

Design and deliver complex mixed-signal blocks from concept through production while coordinating with cross-functional teams.

  • Architect, design, simulate, lay out, and characterize high-speed AMS circuits and large analog blocks.
  • Lead design efforts for major blocks, track deliverables and mentor junior engineers.
  • Perform peer reviews and establish robust design methodology and documentation.
  • Collaborate with packaging and hardware teams to meet signal and power integrity requirements.
  • Develop and execute lab validation plans, debug silicon, and support product bring-up.
  • Ensure designs meet manufacturability and reliability targets through PVT, EM, self-heating and IR drop analysis.

Requirements

Must-have technical experience and skills; list indicates priorities. Education degree requirements are summarized separately below.

  • Proven experience in design, simulation and measurement of high-speed ICs in at least three of the following areas: high-speed serial links (serdes, ADC/DAC), system link modeling, high-performance output drivers, PLLs, clock distribution, opamps/programmable gain amplifiers, and equalization techniques.
  • Hands-on mixed-signal simulation and verification experience (Spectre/APS/SpectreX, AMS flow) and familiarity with Cadence Virtuoso and layout validation tools (Calibre).
  • Experience with high-frequency layout including floorplanning, power/ground routing, analog/digital isolation, and passive component integration.
  • Laboratory validation experience: test setup construction, measurement methodology, and ESD practices.
  • Strong problem-solving skills, attention to detail, and ability to drive complex projects to completion in a team environment.
  • Nice-to-have: experience with FinFET/GAA technologies, EM/IR analysis tools, EMX, mixed-signal AMS simulations, and Matlab-based analysis scripts; experience in electrical transceiver and backplane/cable link applications.

Education Requirements

Minimum qualification options: Bachelor's degree plus 8 years related experience, Master's degree plus 6 years related experience, or PhD plus 3 years related experience. (No specific field-of-study mandated in the posting.)
