No relocation is offered.\nWe’re looking for a Principal AI-Native Software Engineer who can turn complex business needs into intelligent, production-ready software.\nYou’ll work at the intersection of software engineering, agentic AI, LLM-powered applications, and enterprise automation, partnering directly with business and technical stakeholders to move ideas rapidly from concept to production. You’ll build scalable Python services, APIs, agentic workflows, and integrations that enable intelligent automation across AT&T.\nThis is not simply an AI experimentation role. We’re looking for an engineer who knows how to combine emerging AI capabilities with proven software engineering practices to deliver solutions that are secure, reliable, observable, maintainable, and built for production.\nWhat You'll Do:\nDesign and build production-grade AI-enabled applications, backend services, and REST APIs using Python and frameworks such as FastAPI, Flask, or Django.\nCreate agentic AI workflows using LangGraph or similar frameworks, including tool calling, routing, planning and execution, multi-step workflows, and human-in-the-loop patterns.\nPartner directly with business and technical stakeholders in a collaborative 2-in-a-box model, translating ambiguous business challenges into technical designs and working solutions.\nIntegrate AI applications securely with enterprise APIs, databases, event streams, service gateways, and other internal platforms.\nDesign reliable tool and service contracts for AI agents, including schemas, validation, idempotency, retries, rate limits, error handling, and access controls.\nDevelop evaluation strategies for AI and agentic systems, including success criteria, regression testing, prompt/tool validation, guardrails, and release gates.\nImplement RAG, vector search, context engineering, structured outputs, and grounding techniques when appropriate to improve accuracy and usability.\nBuild end-to-end solutions across backend services, databases, and front-end experiences using technologies such as Angular and other modern web frameworks.\nApply secure-by-design practices including authentication, authorization, secrets management, least privilege, auditability, input validation, and PII-aware data handling.\nBuild production observability with logging, metrics, distributed tracing, dashboards, alerting, and incident troubleshooting.\nImplement automated testing, CI/CD, Docker-based deployment, and resilient distributed-system patterns including retries, timeouts, circuit breakers, backpressure, and graceful degradation.\nUse AI coding assistants throughout the engineering lifecycle for code generation, refactoring, testing, debugging, and documentation while maintaining rigorous engineering standards.\nWhat You'll Bring:\nA builder mindset with the ability to move quickly from an ambiguous business problem to a working technical solution.\nStrong understanding of AI-native software development, including how and where LLMs and agentic workflows provide meaningful value.\nHands-on experience developing applications that use LLMs, structured prompting, function/tool calling, output validation, and grounding.\nAbility to build agentic solutions that go beyond simple chat interfaces and execute multi-step workflows, use tools, interact with systems, and manage state.\nStrong knowledge of software architecture, system design, API design, data modeling, distributed systems, and integration patterns.\nExperience designing software for production realities including security, scalability, resiliency, observability, maintainability, and operational support.\nStrong communication skills and the ability to explain technical decisions and tradeoffs to both engineering and non-technical business partners.\nAn AI-augmented engineering approach, using modern AI development tools to accelerate delivery without sacrificing software quality.\nWhat You'll Need:\n8+ years of professional software engineering experience building and delivering production applications or services.\n\nBachelor's degree in Computer Science, Computer Engineering, Software Engineering, a related technical discipline, or equivalent practical experience.\nStrong Python development experience, ideally with FastAPI, Flask, or Django.\nHands-on experience designing and developing REST APIs and backend/microservice architectures.\nExperience integrating applications with enterprise platforms, databases, APIs, or distributed systems.\nStrong knowledge of SQL and relational databases; NoSQL/document database experience is beneficial.\nExperience with unit testing, integration testing, automated testing, CI/CD, code review, and refactoring.\nExperience with Docker and deployment into cloud or enterprise environments.\nWorking knowledge of production monitoring using structured logging, metrics, tracing, performance analysis, and incident troubleshooting.\nUnderstanding of secure API development, authentication/authorization, secrets management, least privilege, and audit logging.\nHands-on experience integrating LLMs or Generative AI capabilities into software applications.\nExperience with tool/function calling, structured prompting, output validation, RAG, retrieval, or other grounding techniques.\nDemonstrated use of AI coding assistants as part of the software development lifecycle.\nPreferred Qualifications:\nHands-on experience with LangGraph or comparable agent orchestration frameworks.\nExperience designing multi-agent or multi-step agentic workflows.\nExperience with Temporal, Celery, Airflow, or other workflow/orchestration technologies.\nKnowledge of event-driven architectures using Kafka, SNS/SQS, Pub/Sub, or comparable technologies.\nExperience implementing RAG, embeddings, semantic/vector search, and vector databases in production environments.\nExperience with OAuth 2.0, OIDC, API gateways, or service mesh technologies.\nExperience developing reusable SDKs, internal developer platforms, AI tool libraries, or reference architectures.\nExperience with Angular or another modern JavaScript/TypeScript front-end framework.\n\nOur Principal Data/AI Engineering jobs earn between $155,400.00 - $261,100.00 USD Annual.
