Acacia designs, develops, manufactures and sells intelligent transceivers using sophisticated signal processing and photonic integration for the 100G, 400G and 1T bit speed fiber optic transmission market deployed in data center, metro, long-haul and ultra-long haul telecommunication networks.

The Sr. Analog/Mixed-signal IC Design Engineer will be a key member in a small, dynamic IC Design team that develops high speed analog designs for optical communications products.  He/she will architect, design, layout, measure and productize ultra-deep sub-micron based products.

Key Essential Functions

  • Collaborate with the mixed-signal team and system teams to define and specify the requirements
  • Responsible for the analog circuit, layout design, and testing of analog/mixed signal circuitry for high speed (>10GS/s) and high accuracy analog designs
  • Review complex IC designs and make any necessary recommendations for improvements
  • Apply and drive solid design methodology from conception to production
  • Influence packaging and hardware design team to ensure signal and power integrity specifications are met
  • Lead a large block on a complex chip and mentor some engineers on an as needed basis

Other Duties

  • Perform other duties as assigned

Minimum Qualifications, Experience, Skills, Education and Certifications

  • Typically requires a BSEE degree with 8 years of relevant experience or an MS degree with 5 years of experience or a PhD with 2 years of experience.

    • Serializers and deserializers
    • Digital-Analog Convertors
    • Analog-Digital Convertors
    • Voltage Regulators
    • High Performance Output Drivers
    • High Performance Phase Locked Loops
    • Efficient clock Transmission/propagation
    • Opamps and Programmable Gain Amplifiers
    • Equalization techniques

Highly desired skills and experience include

  • Direct experience with electrical transceiver applications including backplane and cable communications.
  • Experience with FinFET technology or 16nm or below technology node
  • High-frequency layout experience a plus:
  • Passive component design: inductors, transformers, transmission-lines, etc Floorplanning (power/ground, digital/analog signal routing, etc) Custom transistor layout.
  • Design for manufacturability:

Characterization over PVT (monte-carlo analysis)

Electromigration analysis (using Totem, or equivalent)

Power and IR drop analysis

  • Laboratory Validation:

Solid ESD laboratory practices and methodology Construction of test setup to test specific circuitry Experience in the use of high frequency test equipment (BERT, jitter analyzers, VNA, etc.)

  • Software Experience:

Cadence (virtuoso) Spectre/APS Layout validation tools (Virtuoso or Calibre) Post-layout Extraction (Virtuoso or Calibre) EMX Mixed-signal simulations in AMS

Other Considerations/Qualifications

  • Collaborative team player who can work independently.
  • Possess a track record of innovation. Publications are a plus.

Special Physical/Travel Requirements

  • None

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
