About the Job

Requirements

  • Deep understanding of fiber transmission effects, including power and optical signal-to-noise ratio (OSNR) evolution and fiber nonlinearities, and their impact on optical line system design.
  • Hands-on experience with optical networking equipment, including coherent transponders, erbium-doped fiber amplifiers (EDFAs), Raman amplifiers, and reconfigurable optical add-drop multiplexers/wavelength selective switches (ROADM/WSS), and knowledge of optical transport network (OTN), Ethernet, and software-defined networking (SDN)/generalized multiprotocol label switching (GMPLS) control planes.
  • 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 multilayer networking products, especially at Layer 0 and Layer 1.
  • 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).
  • A Ph.D. in Electrical Engineering, Computer Science, Telecommunications, Optics, Physics, or a related field, plus a minimum of five years of relevant work experience in optical transport or a related telecommunications area; alternatively, an M.Sc. in the same fields plus a minimum of eight years of relevant work experience in optical transport or a related telecommunications area.

Responsibilities

  • Work from business requirements, customer use cases, and industry standards such as ITU-T and IEEE to make and document trade-offs among cost, function, capacity, and performance for network elements such as ROADMs and optical amplifiers.
  • Own the requirements and architecture of assigned Layer 0 feature areas and be accountable for their technical success from concept through release.
  • Shape product features and requirements with Product Line Management, and recommend solutions to new feature requests based on feasibility, cost, and risk.
  • Own system requirements, architecture specifications, and acceptance criteria for assigned feature areas, and guide development teams through implementation and validation.
  • Drive the system architecture of assigned feature areas with fellow architects and development leads, including interfaces and data models.
  • Architect and validate distributed, link-level control loops in assigned feature areas, such as power control, gain and tilt equalization, and transient suppression.
  • Define system design rules and optical performance models used by assigned feature areas, such as target power profiles and OSNR estimation.
  • Partner with the product documentation team to describe features and operational concepts for customers.
  • Lead cross-functional feature teams to build consensus on architecture and technical concepts, and influence their plans and priorities.
  • Represent assigned feature areas in technical engagements and demonstrations with key customers.
  • Mentor engineers and architects on the team.

About the Company

Nokia

Makes network gear for carriers and data centers

Nokia makes the equipment and software that mobile carriers, cloud companies, and businesses use to run networks, from cell-tower radios to fiber links between AI data centers. From 1998 to 2011 it was the world's largest mobile phone maker; it sold that business to Microsoft in 2014, and HMD Global, a separate company, makes Nokia-branded phones under license. Its network unit sells optical systems that send data over fiber, internet routers, and broadband gear, and its mobile unit sells radios and the core software that runs 5G networks. Nokia earns money from equipment and service contracts and from licensing its patents to phone makers and carmakers. It was founded in 1865 as a wood pulp mill and is based in Espoo, Finland.
