As part of Nokia’s Optical Architecture group, you will have a unique opportunity to shape the design of novel DWDM optical line systems. You will architect their Layer0 network element (NE) software in collaboration with our Systems Architecture, Systems Engineering and Software Development teams.
Working from business requirements, customer use cases and industry standards (such as ITU-T and IEEE), you will make and document trade-offs among cost, function, capacity and performance for network elements such as ROADMs and optical amplifiers.
In this role, you will own the requirements and architecture of assigned Layer0 NE software feature areas, and be accountable for their technical success from concept through release. Your key responsibilities will include:
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 software architecture of these feature areas with fellow architects and development leads, including interfaces, data models and control algorithms
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 with key customers
Assessing field issues in these feature areas when called upon by customer support teams
Mentoring engineers and architects on the team
Knowledge / Skills / Abilities
Deep understanding of DWDM line system fundamentals, including amplifiers, ROADMs, power control and OSNR
