Infinera is seeking a Coherent Optical System Architect to join our Advanced Optical Systems Group (OSG). The engineer will work on the design, characterization, and subsequent integration of 400G and 800G coherent pluggables based on Infinera's next-generation coherent photonic integrated circuits (PICs) and FlexCoherent DSP ASICs. The ideal candidate should be prepared to work with early prototype PICs, analog ASICs, and control systems to further the development of short term and long-term enabling technologies.
Your Key Responsibilities Would Include:
Performance characterization of coherent pluggable transceivers, which will include detailed experimental validation of the constituent sub-components that comprise the pluggable, such as the analog, control, and DSP ASICs.
Optical integration of coherent transceivers
Development of calibration algorithms to maximize system level performance.
Perform numerical analysis of coherent transceiver to project system performance.
Be part of cross functional product development teams involving software, electronics, optics and test.
Education & Experience Necessary For Success:
PhD. in Electrical Engineering or Applied Physics with minimum of 3 years of industrial experience in optical communications, photonics, high speed electronics or systems.
Fundamental understanding of optical communication systems, DWDM transmission systems, photonic integrated components, electronic (integrated) circuits, and signal analysis and processing.
Hands-on experience working with system-level optical communication hardware and components.
Extensive understanding of coherent communications systems, including experience with higher order modulation formats.
Experience characterizing high-speed RF and mm-wave interconnects, amplifiers, and components.
Characterization of RF/mm-wave systems, such as S-parameter measurements, jitter measurements, and ADC/DAC performance and ENOB
Hands-on experience with high-speed optical and electrical test, and measurement equipment control and data acquisition.
Programming experience in MATLAB, Python, VB.net, or C desired.
