Principal Solution Architect

Principal Solution Architect Dallas, Texas This position requires office presence of a minimum of 5 days per week and is only located in the location(s) posted. No relocation is offered. Join AT&T and help shape the future of communications and technology that connect the world. We value innovators who seek to explore the unknown and challenge the status quo. Bring your bold ideas and fearless spirit to redefine connectivity and transform how people share stories and experiences. At AT&T, you won’t just imagine the future—you’ll build it. Job Overview: We are hiring Principal Solution Architects to accelerate AI-driven automation across AT&T's Business Technology & Product Development (BTPD) platform. These roles sit at the intersection of enterprise solution architecture and applied AI — designing agentic systems that gather information, build context, and automate complex solutioning workflows. You will own end-to-end technical solutions for major initiatives using modern AI patterns (LangGraph, LangChain, prompt engineering) alongside traditional architecture disciplines. What you’ll do: Design and implement agentic AI systems that automate solutioning workflows — gathering data from heterogeneous sources, constructing context, and producing actionable technical outputs. Architect integration solutions across enterprise platforms ensuring coherent end-to-end data flow and nonfunctional readiness (performance, reliability, security). Build and maintain a "context hub" — a knowledge automation layer that synthesizes business rules, system state, and domain expertise into structured, queryable context for AI agents and human decision-makers. Translate business requirements into robust technical designs: solution intents, integration plans, API contracts, interface specifications, and architecture decision records (ADRs). Define and validate system components, interactions, and trade-offs — producing repeatable engineering artifacts that reduce rework and accelerate delivery. Collaborate with Enterprise Architects, development squads, product owners, and program leadership to align architectural direction across teams and platforms. Drive adoption of AI-augmented engineering practices — prompt engineering, retrieval-augmented generation (RAG), tool-use patterns, and multi-agent orchestration. Evaluate and recommend cloud-native patterns on Azure and AWS for deploying AI workloads at enterprise scale. What you’ll need: 7+ years of experience in solution architecture, systems engineering, or software engineering with increasing scope and complexity. Demonstrated experience designing and delivering AI/ML solutions — particularly agentic or generative AI systems — in a production enterprise environment. Strong Python proficiency; experience with LangGraph, LangChain, or equivalent AI orchestration frameworks. Proven ability to architect cloud-native solutions on Azure and/or AWS (Kubernetes, serverless, managed AI/ ML services). Experience with API design and governance (REST, GraphQL, event-driven architectures). Track record of cross-team technical leadership — aligning multiple squads around a shared architectural vision without formal authority. Excellent written and verbal communication — you produce clear architecture documents, ADRs, and interface specifications. Familiarity with telecom/B2B domain concepts is a plus but not required. What you’ll bring: You can design a multi-agent system from scratch — defining agent roles, tool interfaces, memory/context management, and orchestration flows. You decompose complex enterprise problems into modular, testable architecture components and communicate trade-offs clearly to technical and non-technical stakeholders. You write production-quality Python and can prototype agentic workflows rapidly using LangGraph or equivalent frameworks. You have hands-on experience deploying AI/ML workloads on Azure or AWS (container orchestration, serverless, managed AI services). You thrive at the boundary between systems — connecting billing platforms, order management, product catalogs, and fulfillment systems through well-defined APIs and event-driven patterns.
