Jobbeschreibung

Imagine being part of a team that is fundamentally changing the way people communicate, collaborate, watch TV, and explore the universe through the internet. Utilizing our uniquely differentiated technology, we have created an Intelligent Transport Network with greater speed, capacity, and scalability than ever before. This network of tomorrow will allow for unlimited bandwidth, enabling content and creativity limited only by the imaginations of its users.

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 Nokia’s next‑generation coherent photonic integrated circuit (PIC) and digital signal processor (DSP) technologies. The ideal candidate will work with early prototype PIC, DSP and analog ASIC hardware, performing digital‑optical integration, developing calibration and controls methodologies, and carrying out performance characterization (transceiver SNR, OSNR tolerance, sensitivity studies, etc.). The role requires frequent interaction with the coherent ASIC team, optical, high‑speed analog ASIC and systems engineering teams, and the ability to make trade‑offs between optical, electrical, and digital capabilities to optimize overall system performance.
