Sr. Backend AI Developer

PRIMARY PURPOSE: The Backend AI Developer within the Transformation Office is responsible for building, operating, and scaling the backend systems that power enterprise AI capabilities. This role focuses on implementing reliable, secure, and performant AI services that enable Generative AI, Retrieval‑Augmented Generation (RAG), and agent‑based solutions to integrate with business applications and data platforms.

Operating at the intersection of backend engineering and applied AI, the Backend AI Developer translates approved AI architectures into robust APIs, pipelines, and services, ensuring that AI solutions are production ready, observable, and aligned with enterprise infrastructure standards across AWS and Azure environments.

ESSENTIAL FUNCTIONS AND RESPONSIBILITIES

• Designs and implements backend services and APIs that support Generative AI and LLM‑powered applications, including request orchestration, prompt execution, and inference management.
• Builds and maintains backend components for Retrieval‑Augmented Generation (RAG) solutions, including document ingestion pipelines, embedding services, vector index management, retrieval logic, and response assembly.
• Implements backend support for agent‑based AI systems, enabling task orchestration, state management, tool execution, and interaction with enterprise systems using platforms such as AWS AgentCore and Azure AI Agent Service.
• Develops scalable, maintainable backend code primarily in Python, with supporting use of SQL and PySpark, following secure coding and performance best practices.
• Integrates AI services with enterprise and legacy systems—including SQL Server, on‑prem databases, and mainframe‑adjacent platforms—using approved, non‑invasive integration patterns.
• Implements authentication, authorization, logging, monitoring, and error‑handling mechanisms to ensure AI services meet enterprise security, auditability, and reliability requirements.
• Supports deployment, configuration, and operation of AI backend workloads in AWS and Azure, including containerized and managed service‑based deployments.
• Collaborates closely with Gen AI Architects, Applied AI Developers, data engineers, and infrastructure teams to ensure backend implementations align with architectural standards and business needs.
• Troubleshoots and resolves backend performance issues related to latency, throughput, cost, and reliability of AI services.
