As part of Nokia’s Optical Architecture group, you will have a unique opportunity to shape the design of novel DWDM optical line systems, from transmission performance to link-level control. Working with our Systems Architecture, Systems Engineering and Software Development teams, you will turn emerging optical technologies into competitive products.
How You Will Contribute And What You Will Learn
In this role, you will lead the architecture of assigned line systems, and be accountable for their technical success from concept through release. Your key responsibilities will include:
- Translating Product Line Management requirements into line system architecture, and documenting trade-offs among performance, cost, risk and schedule
- Optimizing end-to-end, multi-band (C+L) transmission performance, accounting for effects such as signal power/OSNR evolution and fiber nonlinearities
- Directing the design and validation of distributed, link-level control loops, such as power control, gain and tilt equalization and transient suppression
- Setting the system design rules and optical performance models, such as target power profiles, OSNR and quality-of-transmission (QoT) estimation
- Owning the system requirements, architecture specifications and acceptance criteria for these line systems, and leading design reviews with fellow architects and multi-site engineering teams
- Influencing and aligning cross-functional teams, from systems engineering through test and field deployment, on plans and priorities
- Representing Nokia’s Optical Architecture group in technical engagements with key customers, including demonstrations of new optical transmission technologies
- Mentoring architects and engineers, and guiding their technical work
Knowledge / Skills / Abilities
- 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 of their transmission over long-haul systems
- Familiarity with AI tools, such as large language models (LLMs) and agents, and their use in product specification and development
