System Architect - OLS (Optical Line Systems)

NION2026

As part of Nokia’s Optical Architecture group, you will have a unique opportunity to lead the design and architecture of novel optical DWDM communication systems.  You will be responsible for architecting and implementing new software platforms in collaboration with our Systems Architecture, Systems Engineering and Software Development teams.

Develop innovative, competitive product architectures and requirements for packet-optical telecommunications products based on understanding of business requirements, use cases and applicable industry standards (like ITU, IEEE). Consider trade-off between cost, function, capacity and performance. The products to develop include optical network equipment, such as optical line systems, ROADMs, optical line interfaces/transponders/muxponders, OTN switches and other transport and switching network elements. 
 

• Partnering with Product Line Management to define and clarify system & product concepts, features & requirements, including customer use cases and experience expectations.
• Translate the product requirements into system architectural specifications and requirements.
• Work closely with a team of architects and SW developers in establishing the SW architectural specifications.
• Lead the cross-functional feature teams to facilitate & build consensus on product architecture and technical concepts for product implementation.
• Engage with SW development teams to provide architecture know-how to the teams and maintain alignment of the implementation with the architecture.
• Documentation of product architecture, requirements and concepts in clear, concise and consistent specifications.
• Investigate new feature requests and customer requirements; propose feature solutions and assess feasibility.
• Work closely with the product documentation team to describe product features and operational concepts in customer documentation.

You have:

• Advanced graduate degree in Electrical Engineering, Computer Science, Telecommunication or equivalent education.
• Ph.D. + minimum 5 years of relevant work experience
• M.Sc. + minimum 8 years of relevant work experience in optical transport systems or related fields in telecommunications.
• Broad systems knowledge garnered by years of experience specifying and/or leading architectural specifications across multi-disciplines
• Experience defining requirements in the areas of Fault Management, Performance Management, Configuration Management, Service Provisioning and Control Plane features of multi-layer networking products (especially for the L0 and L1 layers)
• Experience with Optical Networking Technologies and Standards including ROADM/WSS, OTN, Ethernet, GMPLS Control Plane
• Experience designing and validating link-level control algorithms and optical performance monitoring to optimize end-to-end optical performance.
• Excellent communication and presentation skills

Nice-to -Have

• Ability to think big-picture and deliver high quality requirements/architecture specifications, geared towards building robust, reliable and the best user experience solutions for the end-to-end integrated system  
• Highly motivated team player adept at cross-functional, cross-cultural and international teamwork
