Optical Hardware Engineering Technical Leader, Acacia (Hybrid)

Responsibilities

• With your expertise in optical transceivers, control algorithms and verification, you help the team to develop the next generation of low-power and high-performance transceivers. Here are some examples of possible topics:
• 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

Requirements

• 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
• Experience with test automation, ideally with Python
• Hands-on experience with high-speed RF electronics and ADC/DAC
• Why Cisco?
• We are Cisco, and our power starts with you.
• Message to applicants applying to work in the U.S. and/or Canada:
