ElectronicsEnterprise SoftwareInternet of ThingsMobile DevicesTelecommunications
Responsibilities
Contributing to the development of leading coherent MODEMs based on Infinera's next-generation coherent photonic integrated circuits (PICs)
Develop and maintain state-of-the-art simulation environments that guide Nokia’s MODEM design including its digital, analog and optical sub-systems
Model and systematically breakdown all MODEM impairments with continuous alignment to experimental measurements of early prototype hardware
Guide major design decisions and serve as invaluable feedback to cross-functional design teams throughout the entire development cycle of Nokia’s next generation optical engines
Understand and make tradeoffs between optical, electrical, and digital capabilities in order to optimize the overall vertically integrated system performance
Evaluate the effectiveness of state-of-the-art digital signal processing algorithms
Estimate the impact of transistor-level design choices in analog circuits and predict the MODEM performance penalties of integrated optical components such as Mach-Zehnder modulators and semiconductor optical amplifiers
Project the reach of our optical engines based on various linear and nonlinear impairments of the optical fiber channel and deployed line-systems
Assist in design, finding relationships between low level hardware specifications and its system level impact and optimizing performance-critical aspects to maximize overall modem performance
Present results internally and document as electrical and optical performance specifications for next-generation platforms
Engage in external and customer-facing interactions, discussing expected improvements of our next-generation engines on customer networks and contributing to forums discussing multi-source vendor agreements
Qualification
Required
PhD. in Electrical Engineering or Applied Physics with 0- 3 years of industrial or academic experience in optical communications, photonics, high speed electronics or systems
