Mixed - signal/analog IC Designer

Mixed-Signal IC Design Engineer

Acacia Communications, a leader in disruptive optical and coherent technology, is looking for a mixed-signal IC Design Engineer. The candidate will be a key member in a small, dynamic IC Design team that develops millimeter-wave circuits for Acacia's silicon photonics-based optical transponders. The candidate will architect, design, layout, measure, and productize silicon-based transmitters and receivers, operating up to 400-Gb/s/lane, and beyond.

Responsibilities:

• Work with the digital, mixed-signal, hardware, and PIC teams to co-architect electro-optic TX and RX IC solutions to meet transponder-level specifications
• Schematic-design, layout, and laboratory-characterization of mm-wave ICs with emphasis on novel biasing techniques, integrated power delivery, and built-in self-test.
• Set and track IC macro-development, internal-DVT, qualification, and production-test schedules
• Work with contract manufacturers to manage qualification and high-volume production-testing of ICs

Experience:

• Bachelors +15 years, Masters +12 years, PhD + 8 years of related experience.
• Experience in analog and mixed-signal biasing techniques in nanoscale CMOS (22FDX, 5nm finFET), with emphasis on BIST (built-in self test)
• Experience in power systems, Low-Dropout Regulator design, and high-speed control loops (1k-100MHz)

Design, simulation, and measurement (at wafer-level) of control circuitry for the following types of macros, operating at or above 25-Gb/s:

• Linear amplifiers/drivers
• Transimpedance amplifiers
• AGC circuits
• Linear equalizers
• SERDES

Additional Experience:

• Experience collaborating with team and working independently
• You have authored publications demonstrating innovation
• Experience with coherent optical communications links as well as electrical transceiver applications including backplane and cable communications
• Experience designing, measuring, and integrating analog/mixed-signal transmitter/receiver IC or IP into a standalone packaged-component or a larger subsystem intended for high-volume production
