Résumé du poste

Nokia is seeking a Coherent Optical System Architect to join our Optical Systems Group (OSG). The engineer will contribute to development of leading coherent MODEMs based on Infinera's next-generation coherent photonic integrated circuits (PICs).

The ideal candidate will work with early prototype hardware to assess product performance and provide rapid feedback to PIC and high-speed analog ASIC teams. Responsabilities include owning optical design, optimization methods, and stabilization

Qualifications

• PhD. in Electrical Engineering or Applied Physics with minimum of 3 years of industrial experience in optical communications, photonics, high speed electronics or systems.
• 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, and ADC/DAC performance and ENOB
• Hands-on experience with high-speed optical and electrical test, and measurement equipment control and data acquisition.
• Programming experience in Matlab, Python, VB.net, or C desired.

Responsabilités

• Nokia’s next generation communications platform will be defined, developed, characterized, and optimized on your optical testbed. Your experimental data will fuel our design, starting with off-the-shelf components, evolving to prototype PICs, and eventually taking the form of the final integrated embedded systems or coherent pluggable modules. This requires ownership of the optical design, optimization methods, and stabilization techniques. One particular component of your research will be pushing our optical systems to higher baud rates.
• Frequently used diagnosis capturing coherent waveforms on a high-speed oscilloscope and performing coherent signal processing on waveforms, and measuring bit-error rate performance in the presence of optical noise and other impairments. Of particular interest will be pushing to faster baud rates.
• Through frequent interaction with the control & firmware teams, you will assist in optimizing performance-critical aspects such as powerup self-calibration, receive acquisition, real-time performance monitoring, and in-service performance optimization. These algorithms will be tested during the implementation stage to ensure they operate properly.
• Results will be presented internally and documented as electrical and optical performance specifications for next-generation platforms.
• Some customer-facing interactions may be required, such as field trials using prototype equipment, or debugging unusual field failures that cannot be resolved through the normal customer service process.
