Job description

In an increasingly connected world, the pandemic has highlighted just how essential telecom networks are to keeping society running. The Network Infrastructure group is at the heart of a revolution to connectivity, pushing the boundaries to deliver more and faster network capacity to people worldwide through our ambition, innovation, and technical expertise

Join Optical Networks division, where innovation meets scale in the AI-driven data center era. With the recent acquisition of Infinera, we've united two industry leaders to create an optical networking powerhouse-combining cutting-edge technology with proven leadership to redefine the future of connectivity.

Infinera is now part of the Nokia Corporation and its subsidiaries. When you apply, the information you share will be handled with care and used only for recruitment purposes within the group.

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.

• 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.
