Coherent Systems Architect - Optical Modem Development and Optimization

Job Summary

Nokia is seeking a Coherent Optical Systems Engineer to join their Optical Systems Group (OSG). The engineer will contribute to the design, characterization, and development of leading coherent optical transceivers based on Nokia's next-generation coherent photonic integrated circuit (PIC) and digital signal processor (DSP) technologies.

About the Role

The ideal candidate will work with early prototype PIC, DSP, and analog ASIC hardware; develop robust calibration and controls methodologies; and carry out performance characterization. This role involves understanding and making tradeoffs between optical, electrical, and digital capabilities to optimize overall system performance.

Responsibilities

• Contribute to the design, characterization, and development of leading coherent optical transceivers based on Nokia’s next-generation coherent PIC and DSP technologies.
• Perform digital-optical integration, develop robust calibration and controls methodologies, and carry out performance characterization.
• Characterize coherent pluggable transceivers, including detailed experimental validation of constituent sub-components like analog, controls, and DSP ASICs.
• Actively participate in cross-functional product development teams involving software, electronics, optics, and test.

Requirements

• 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.
• Programming experience in Matlab, Python, VB.net, or C desired.

Qualifications

• Understanding and making tradeoffs between optical, electrical, and digital capabilities to optimize overall system performance.
