Sr. Systems Architect

About the role

As part of Nokia’s Optical Architecture group, you will lead the design and architecture of novel optical DWDM communication systems. You will architect and implement new software platforms in collaboration with Systems Architecture, Systems Engineering, and Software Development teams. The role involves developing innovative, competitive product architectures and requirements for packet-optical telecommunications products based on business requirements, use cases, and industry standards (e.g., ITU, IEEE). You will evaluate trade-offs between cost, function, capacity, and performance for products including optical network equipment such as optical line systems, ROADMs, optical line interfaces/transponders/muxponders, OTN switches, and other transport and switching network elements.

Responsibilities

• Work cooperatively with Product Line Management to define and clarify system and product concepts, features, and requirements, including customer use cases and experience expectations.
• Translate product requirements into system architectural specifications and requirements.
• Collaborate with architects and software developers to establish software architectural specifications.
• Lead cross-functional feature teams to build consensus on product architecture and technical concepts for implementation.
• Engage with software development teams to provide architectural guidance and maintain alignment with the architecture.
• Document product architecture, requirements, and concepts in clear, concise, and consistent specifications.
• Investigate new feature requests and customer requirements; propose solutions and assess feasibility.
• Work with the product documentation team to describe product features and operational concepts in customer documentation.

Requirements

• Broad systems knowledge from years of experience specifying or leading architectural specifications across multiple disciplines.
• Ability to think big-picture and deliver high-quality requirements and architecture specifications for robust, reliable, and user-friendly end-to-end integrated systems.
• Experience defining requirements in areas such as Fault Management, Performance Management, Configuration Management, Service Provisioning, and Control Plane features of multi-layer networking products (especially L0 and L1 layers).
• Experience with Optical Networking Technologies and Standards, including ROADM/WSS, OTN, Ethernet, and GMPLS Control Plane.
• Familiarity with data models for operating and monitoring optical networks, including YANG modeling language, ONF TAPI, OpenROADM, and OpenConfig.
• 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.

Qualifications

Advanced graduate degree in Electrical Engineering, Computer Science, Telecommunication, or equivalent education. Ph.D. with a minimum of 5 years of relevant work experience.
