Senior Backend Engineer

Senior Backend Engineer to architect and develop the production-grade application infrastructure for an AI-driven transformation. In this pivotal role, you will design and implement the secure, high-performance backend systems that serve as the foundational 'nervous system' for AI agents, enabling seamless interaction between Large Language Models (LLMs) and critical enterprise systems such as industrial ERPs and sensitive engineering data. As the technical lead for Workstream 2: Build, you will move beyond basic model serving to construct robust, on-premise microservices that power the clients engineering platform and autonomous iAI agents. Operating within a structured Stage Gate delivery framework, you will ensure all software adheres to stringent security, reliability, and compliance standards—essential for national defense infrastructure applications. Your work will directly enable AI agents to autonomously execute complex tasks, including drafting defense contracts, forecasting supply chain disruptions, and validating engineering design safety. This role demands expertise in distributed systems architecture, enterprise integration, and defense-grade security protocols. You will architect scalable API gateways, orchestration layers for agentic frameworks, and secure data access mechanisms for SAP S/4HANA, Ariba, and other enterprise systems. Additionally, you will optimize on-premise deployments for high concurrency, low latency, and strict auditability, ensuring seamless integration with front-end teams and data scientists to deliver a cohesive, production-ready AI platform.
