Job description

Job Description

As part of Nokia’s Optical Architecture group, you will have a unique opportunity to contribute to 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.

How You Will Contribute And What You Will Learn

• Work cooperatively 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.
• Participate in 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 and domain know-how to the teams.
• Support SW development teams during feature implementation and validation, ensuring 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 collaboratively with the product documentation team to describe product features and operational concepts in customer documentation.

Key Skills And Experience

• Excellent foundational systems knowledge with experience specifying architectural specifications across multi-disciplines.
• 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.
• 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, SDN/GMPLS Control Plane.
• Familiarity with data models used for operating and monitoring optical networks including YANG modelling language, ONF TAPI, OpenROADM, and OpenConfig.
• Familiarity with the SONiC Optical Transport Network Working Group including the Optical Transport Abstraction Interface (OTAI).
• Experience in programming in Python or Matlab and solid troubleshooting skills.
• Experience designing and validating link-level control algorithms and optical performance monitoring to optimize end-to-end optical performance.
• Excellent communication and presentation skills.
• Highly motivated team player adept at cross-functional, cross-cultural and international teamwork.

Education & Experience Requirements

• Advanced graduate degree in Electrical Engineering, Computer Science, Telecommunication or equivalent education.
• Ph.D. + minimum 3+ years of relevant work experience
• M.Sc. + minimum 6+ years of relevant work experience in optical transport systems or related fields in telecommunications.
