What Do We Expect From You

As a Senior Architect focused on Technology within Product Architecture, you will address a critical gap in senior design ownership across multiple OSS domains. This role is key to defining robust, reusable design patterns and ensuring all product increments align with core architectural principles. Your expertise will be crucial in driving technical consistency, accelerating development velocity, and ensuring the long-term scalability and maintainability of our OSS product portfolio.

Responsibilities:

Cross-Domain Architectural Design & Ownership:

• Provide senior design ownership and architectural guidance across various OSS domains, ensuring coherent and consistent solutions.
• Lead the design of complex features and components, ensuring they are scalable, performant, and aligned with overall product architecture.
• Translate product requirements and strategic objectives into clear, actionable architectural specifications and designs.

Horizontal Architectural Convergence:

• Lead the architectural design efforts to achieve convergence and seamless interoperability across service assurance, orchestration, and network slicing domains.
• Define common architectural patterns, APIs, and data models that enable these distinct but interconnected domains to work cohesively.
• Identify and resolve architectural conflicts or redundancies between different product components to ensure a unified solution.

Reusable Design Patterns & Frameworks:

• Identify, define, and promote the adoption of reusable design patterns, architectural frameworks, and best practices across product teams.
• Develop and maintain architectural blueprints and reference implementations to guide engineering efforts.
• Drive standardization of technologies and approaches where appropriate to reduce complexity and improve efficiency.

End-to-End Solution Architecture:

• Architect comprehensive end-to-end solutions that span multiple OSS functions, ensuring data flow, control planes, and user experiences are harmonized.
• Collaborate with individual domain architects (e.g., Assurance, Orchestration, Slicing) to align their specific designs with the overarching convergence strategy.
• Ensure architectural designs support future scalability, resilience, and extensibility across the converged domains.

Roadmap Alignment & Execution

• Translate product roadmap initiatives into detailed architectural plans, prioritizing efforts that enhance convergence and interoperability.
• Work closely with product management and engineering leads to break down large initiatives into manageable architectural increments.
• Anticipate future technical challenges related to cross-domain integration and proactively design solutions.
