Principal Systems Architect – Layer0 NE Software

As part of Nokia’s Optical Architecture group, you will have a unique opportunity to shape the design of novel DWDM optical line systems. You will architect their Layer0 network element (NE) software in collaboration with our Systems Architecture, Systems Engineering and Software Development teams. Working from business requirements, customer use cases and industry standards (such as ITU-T and IEEE), you will make and document trade-offs among cost, function, capacity and performance for network elements such as ROADMs and optical amplifiers. Knowledge / Skills / Abilities Deep understanding of DWDM line system fundamentals, including amplifiers, ROADMs, power control and OSNR Extensive experience defining fault, performance and configuration management, service provisioning and control plane requirements for multi-layer networking products, especially at L0 and L1 Experience with optical networking technologies and standards, including ROADM/WSS, OTN, Ethernet and SDN/GMPLS control plane Experience designing and validating link-level control algorithms and optical performance monitoring to optimize end-to-end transmission Working knowledge of data models for operating and monitoring optical networks, including YANG, ONF TAPI, OpenROADM and OpenConfig Familiarity with the SONiC Optical Transport Network Working Group, including the Optical Transport Abstraction Interface (OTAI) Familiarity with AI tools, such as large language models (LLMs) and agents, and their use in product specification and development Broad systems expertise, with a track record of writing and leading high-quality requirements and architecture specifications for robust, reliable end-to-end systems Sound, independent judgment on ambiguous and novel technical problems Excellent communication and presentation skills for internal and customer audiences Highly motivated collaborator, effective in cross-functional, cross-cultural and international teams Education & Experience Requirements: Ph.D. in Electrical Engineering, Computer Science, Telecommunications or a related field + minimum 5 years of relevant work experience in optical transport or a related telecommunications area M.Sc. in the same fields + minimum 8 years of relevant work experience in optical transport or a related telecommunications area
