Coherent Optical Systems Engineer

Design coherent optical transceivers at Nokia using digital-optical integration, calibration controls, and performance characterization expertise.
As a Coherent Optical Systems Engineer in Nokia’s Optical Systems Group, you will contribute to transceiver design, characterization, and development. The work uses Infinera’s next-generation coherent photonic integrated circuit and digital signal processor technologies. You will work with prototype PIC, DSP, and analog ASIC hardware while balancing optical, electrical, and digital capabilities.

Key Responsibilities:

Integrate digital and optical components in coherent transceivers
Develop calibration and controls methodologies for system performance
Characterize transceiver SNR, OSNR tolerance, and sensitivity
Validate analog, controls, and DSP ASIC sub-components experimentally
Collaborate across software, electronics, optics, and test teams
Requirements:
Ph.D. in Electrical Engineering or Applied Physics
Experience in optical communications, photonics, electronics, or systems
Understanding of DWDM, fiber penalties, PICs, circuits, and signal processing

Experience with coherent communications, QPSK, 16

QAM, 64

QAM, and FEC
Hands-on optical, electrical, RF, or millimeter-wave testing experience
Apply coherent communications, prototype hardware, and signal analysis expertise to Nokia transceiver development and characterization.
