In this role, you will own the requirements and architecture of assigned Layer0 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 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
