About the role
Nokia's optical networking group (NILightpath) develops Layer0 optical transport systems, working from business requirements, customer use cases and industry standards such as ITU-T and IEEE, and designing network elements such as ROADMs and optical amplifiers. This role owns the requirements and architecture of assigned Layer0 feature areas, architecting link-level control loops and optical performance models. It also leads cross-functional teams, engages key customers, and mentors engineers and architects from concept through release.
What you will do
- Shaping product features and requirements with Product Line Management, and recommending solutions to new feature requests based on feasibility, cost and risk
- Owning the system requirements, architecture specifications and acceptance criteria for these feature areas, and guiding development teams through implementation and validation
- Driving the system architecture of these feature areas with fellow architects and development leads, including interfaces and data models
- Architecting and validating the distributed, link-level control loops in these feature areas, such as power control, gain and tilt equalization and transient suppression
- Defining the system design rules and optical performance models these feature areas rely on, such as target power profiles and OSNR estimation
- Partnering with the product documentation team to describe features and operational concepts for customers
- Leading cross-functional feature teams to build consensus on architecture and technical concepts, and influencing their plans and priorities
- Representing these feature areas in technical engagements and demonstrations with key customers
- Mentoring engineers and architects on the team
Skills used in this role
What the employer is looking for
- Deep understanding of fiber transmission effects, such as power and OSNR evolution and fiber nonlinearities, and their impact on optical line system design
- Hands-on experience with optical networking equipment, including coherent transponders, EDFAs, Raman amplifiers and ROADM/WSS, and knowledge of OTN, Ethernet and SDN/GMPLS control plane
- Experience designing and validating closed- and open-loop, link-level control algorithms and optical performance monitoring to optimize end-to-end transmission
- Broad systems expertise, with a track record of writing and leading high-quality requirements and architecture specifications for robust, reliable end-to-end systems
- Extensive experience defining fault, performance and configuration management, service provisioning and control plane requirements for multi-layer networking products, especially at L0 and L1
- 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)
- 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
- Ph.D. in Electrical Engineering, Computer Science, Telecommunications, Optics, Physics 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
