Original job description

Job Description

Nokia is seeking a Coherent Optical Systems Engineer to join our Optical Systems Group (OSG). The engineer will be responsible for contributing to the design, characterization, and development of leading coherent optical transceivers based on Infinera's next-generation coherent photonic integrated circuit (PIC) and digital signal processor (DSP) technologies. The ideal candidate should be prepared to work with early prototype PIC, DSP, and analog ASIC hardware; to perform digital-optical integration, develop robust calibration and controls methodologies, and carry out performance characterization. Performance characterization will include transceiver SNR, OSNR tolerance, sensitivity studies, etc. OSG works closely with many parts of the company and the candidate should anticipate frequent interactions with the DSP, PIC, analog ASIC, and systems engineering teams. A key component of this role is the ability to understand and make tradeoffs between optical, electrical, and digital capabilities, in order to optimize the overall system performance.

How You Will Contribute And What You Will Learn

Digital-optical integration of next-generation coherent optical transceivers
Development of calibration and controls algorithms to maximize system level performance
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, controls, and DSP ASICs
Active member of the cross-functional product development team involving software, electronics, optics, and test

Key Skills And Experience

Ph.D. in Electrical Engineering or Applied Physics with experience in optical communications, photonics, high-speed electronics or systems
New Ph.D. graduates, as well as experienced professionals, are encouraged to apply.
Fundamental understanding of optical communication systems, DWDM transmission systems, fiber transmission penalties, 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 QPSK, 16QAM, and 64QAM, as well as coding and forward error correction algorithms
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, ADC/DAC performance and ENOB
Hands-on experience with high-speed optical and electrical tests, measurement equipment control, and data acquisition
Programming experience in Matlab, Python, VB.net, or C desired
