Software Solutions Architect – Network Domain

AT&T is seeking a highly skilled Solution Architect to join our team for a strategic, high-profile, large-scale, and complex system initiative.

This project centers on building AT&T’s next-generation network, with a primary focus on developing a network inventory system (OSS) and migrating data from existing legacy systems. The system is distinguished by its complexity, a massive database (over 15 billion objects), the integration of RDBMS, JSON, and graph databases, as well as stringent resiliency and performance requirements, and sophisticated underlying workflows.

The Solution Architect will be a key member of the discovery team, which includes project managers, product managers, team leaders, application DBAs, DevOps engineers, test architects, and other solution architects.

Responsibilities:

• Collaborate with the discovery team to design solutions (epics and user stories) that meet both functional and non-functional requirements
• Support development teams throughout the solution implementation process
• The system is currently built on Azure, but is meant to be multi-cloud in the future. The technology stack is AKS, Node.js, GraphQL, PostgreSQL, Neo4j, Kafka, Redis.

Requirements:

• Extensive experience as a Software Solutions Architect, preferably designing large-scale systems
• Strong ability to conceptualize and visualize complex systems (“big picture thinking”) and create clear architectural diagrams
• Skilled in translating product requirements into detailed technical specifications and system designs
• Proficient in defining non-functional requirements, including security, scalability, reliability, and performance
• Mastery of modern architecture best practices and design patterns
• Expertise in cloud-native architectures, including microservices, serverless functions, containers, and orchestration platforms like Kubernetes
• Proficient in UML modeling techniques, especially ERD (Entity-Relationship Diagrams), sequence diagrams, state charts, and use case diagrams
• Deep knowledge of modern development toolchains and ecosystems supporting scalable systems
• Strong backend development experience, preferably with Java Spring Framework and/or Node.js
• Experienced in database design and management, covering SQL, NoSQL, and big data technologies
• Proven expertise in cloud solutions design, with a preference for Microsoft Azure environments
• Familiarity with CI/CD pipelines, Agile methodologies, and software development lifecycle (SDLC) toolchains
• Solid understanding of infrastructure and security principles and best practices
• Preferably knowledgeable in quality assurance and systems testing methodologies
• Ability to perform Cost-Benefit Analysis (CBA) for architectural decisions and lead Proof of Concept (POC) initiatives to validate solutions
