Job description

Overview

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 Nokia’s next-generation coherent photonic integrated circuits (PICs).

The ideal candidate will develop and maintain state-of-the-art simulation environments that guide Nokia’s MODEM design including its digital, analog and optical sub-systems. This involves the modeling and systematic breakdown of all MODEM impairments with continuous alignment to experimental measurements of early prototype hardware. Sophisticated simulation platforms 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.

OSG works closely with many parts of the company and the candidate should anticipate frequent interactions with the digital ASIC team on digital signal processing aspects and with photonic integrated circuit, high-speed analog ASIC, and line-systems engineering teams. Additionally, OSG frequently works with customers and internal networking groups on performance projections and network level impact of our coherent MODEMs.

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 vertically integrated system performance.

Responsibilities

• 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 break down all MODEM impairments with continuous alignment to experimental measurements of early prototype hardware.
• Provide feedback to cross-functional design teams throughout the development cycle of Nokia’s next generation optical engines.
• Anticipate frequent interactions with the digital ASIC team on digital signal processing aspects and with photonic integrated circuit, high-speed analog ASIC, and line-systems engineering teams.
• Work with customers and internal networking groups on performance projections and network level impact of our coherent MODEMs.
• Understand and make tradeoffs between optical, electrical, and digital capabilities in order to optimize the overall vertically integrated system performance.

Qualifications

• Experience developing and maintaining simulation environments for MODEM design and related subsystems (digital, analog, optical).
• Experience modeling MODEM impairments and aligning models to experimental measurements of hardware prototypes.
• Ability to collaborate with digital signal processing teams, photonic integrated circuit teams, high-speed analog ASIC teams, and line-systems engineering groups.
• Ability to evaluate tradeoffs between optical, electrical, and digital capabilities to optimize system performance.
