Optical Systems Architect
About The Position
As part of Nokia’s Optical Architecture group, the Optical Systems Architect shapes the design of novel DWDM optical line systems, from transmission performance to link-level control. The role works with Systems Architecture, Systems Engineering, and Software Development teams to turn emerging optical technologies into competitive products. The architect leads assigned line-system architecture and is accountable for technical success from concept through release. The position also involves aligning cross-functional teams, representing the Optical Architecture group in customer technical engagements, and mentoring architects and engineers.
Requirements
- Expert knowledge of DWDM systems and fiber transmission effects, and how to account for them in system design.
- Hands-on experience with optical networking equipment, including coherent transponders, EDFAs, Raman amplifiers, and ROADMs.
- Experience designing and validating closed- and open-loop, link-level control algorithms.
- Experience building system design rules and optical performance models, including power budgets, OSNR estimation, QoT estimation, and transmission penalties.
- Knowledge of advanced coherent modulation formats, with hands-on experience transmitting them over long-haul systems.
- Familiarity with AI tools, such as large language models (LLMs) and agents, and their use in product specification and development.
Responsibilities
- Translate Product Line Management requirements into line-system architecture and document trade-offs among performance, cost, risk, and schedule.
- Optimize end-to-end, multi-band (C+L) transmission performance, accounting for signal power and OSNR evolution and fiber nonlinearities.
- Direct the design and validation of distributed, link-level control loops, such as power control, gain and tilt equalization, and transient suppression.
- Set system design rules and optical performance models, including target power profiles, OSNR, and quality-of-transmission (QoT) estimation.
- Own system requirements, architecture specifications, and acceptance criteria for line systems, and lead design reviews with fellow architects and multi-site engineering teams.
- Influence and align cross-functional teams, from systems engineering through test and field deployment, on plans and priorities.
- Represent Nokia’s Optical Architecture group in technical engagements with key customers, including demonstrations of new optical transmission technologies.
- Mentor architects and engineers and guide their technical work.
