• 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
