Lead Coherent Optical Transceiver Hardware Engineer

Cisco Systems, Inc.; Maynard (MA); On-site; USD 179,000 - 254,000; Full time

Job summary

Cisco Systems, Inc. in Maynard, MA is seeking experienced optical transceiver engineers to join the Acacia team developing high-performance, low-power coherent transceivers. You will work with DSP, SW, HW, and PIC teams to optimize designs and verify performance for high-volume manufacturing.

You will contribute to calibration procedures, test development, and production readiness to maximize yield and minimize power. Strong background in photonics and coherent communications is required.

Qualifications

• Bachelor's Degree with 12+ years of experience or Master's degree with 8 years of experience, or PhD with 5 years of related experience.
• Demonstrated experience with coherent optical communications and DSP optimization.
• Demonstrated experience with photonics integrated circuits and their controls for coherent optical transmission.

Responsibilities

• Bring-up and optimization of each new coherent transceiver design, including optimization of operating conditions of optical and electrical components.
• Provide guidance and test results for the development of the integrated optics, high speed electronics, and DSP to maximize performance and minimize size and power consumption of Cisco's coherent optical transceivers.
• Design verification testing (DVT) of coherent transceivers to ensure optical specifications are met over operating conditions (temperature, power levels, etc.).
• Development of calibration and test procedures to ensure consistent high transceiver performance over a wide range of operating conditions (temperature, production variation, ageing, power levels, etc.).
• Work with the operations team to bring these calibration procedures and production tests into high volume manufacturing in a fast, reliable and cost-effective way.
• Work with the operations team to maximize the product yield through good calibration and production test procedures.
• Debug of transceivers, both during bring-up and volume manufacturing.
