Senior Agentic AI Software Engineer

Location: United States – Remote Clearance: Ability to obtain and maintain a Public Trust LTS is seeking a Senior Agentic AI Software Engineer to build the intelligence behind the platform—the autonomous agents, orchestration layers, retrieval pipelines, reasoning workflows, and backend services that transform complex legacy software into actionable engineering knowledge. The Agentic AI platform is designed to help engineers understand, analyze, and modernize one of the most consequential legacy software systems still operating today. Our platform enables engineers to ask questions in plain English and receive explainable, verifiable answers traced directly back to decades of production source code. Rather than replacing engineers, we're building AI that accelerates engineering through transparency, traceability, and intelligent reasoning. We're building an AI-native engineering platform supporting the modernization of mission-critical healthcare systems serving millions of Veterans nationwide. Every response generated by the platform must be explainable, grounded in evidence, and trusted by engineers responsible for maintaining software that millions of people quietly depend on every day. The platform is designed for deployment across federal enterprise environments and is being engineered to align with FedRAMP security controls, Zero Trust principles, and federal compliance requirements. The product has executive sponsorship, committed users, and a customer investing in long-term modernization. Our engineering team is intentionally small. Every engineer has meaningful ownership, significant technical influence, and the opportunity to help define how AI transforms software engineering. We don't simply build AI-powered software—we build software with AI. This is not another chatbot. Using LLMs, autonomous agents, AI-assisted development, parallel workflows, and model-driven engineering is simply how we work. What You’ll Do: Build Intelligent Agentic Systems Design, develop, and deploy autonomous and multi-agent AI systems capable of reasoning, planning, tool use, workflow automation, and human-in-the-loop collaboration. Build intelligent orchestration pipelines coordinating LLMs, specialized agents, enterprise tools, and structured reasoning workflows. Develop reusable agent architectures and orchestration patterns that accelerate intelligent application development across the platform. Engineer Enterprise Retrieval & Knowledge Systems Design and optimize Retrieval-Augmented Generation (RAG) pipelines including document ingestion, embeddings, hybrid retrieval, reranking, semantic search, context engineering, and prompt orchestration. Integrate AI systems with source code repositories, enterprise documentation, APIs, structured data, and knowledge repositories. Ensure every AI-generated response is explainable, evidence-based, and traceable to authoritative sources. Build Production Software Design and implement scalable backend services, APIs, and cloud-native applications supporting enterprise AI workloads. Develop distributed systems capable of serving low-latency AI experiences while maintaining security, reliability, and observability. Optimize performance, latency, throughput, model quality, and infrastructure cost across production AI systems. Deliver Reliable AI Implement testing, evaluation, monitoring, observability, guardrails, and LLMOps practices to ensure AI systems remain trustworthy and production-ready. Continuously evaluate emerging models, frameworks, and engineering practices to improve platform capabilities. Build AI systems that behave predictably in highly regulated enterprise environments. Collaborate Across the Product Team Partner closely with AI architects, platform engineers, front-end engineers, designers, and product leaders to deliver cohesive AI-powered experiences. Mentor engineers through technical leadership, architecture discussions, design reviews, and collaborative problem solving. Help es…
