Principal Coherent Systems Engineer

Location: France; Hybrid

Nokia is seeking a Coherent Optical System Architect to join our Optical Systems Group (OSG). The engineer will be responsible for contributing to the development of leading coherent MODEMs based on Infinera's next-generation coherent photonic integrated circuits (PICs). The ideal candidate will be prepared to work with early prototype hardware to get an initial look at product performance and provide rapid feedback to the PIC and high-speed analog ASIC teams. Performance characterization will include MODEM SNR, OSNR tolerance, systematic breakdown of the MODEM impairment penalties, sensitivity studies and model alignment. OSG works closely with many parts of the company and the candidate should anticipate frequent interactions with the coherent ASIC team on coherent signal processing issues and ADC/DAC ENOB, with optical, high-speed 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.
