AI Applications & Cloud Engineer

About Limestone

Input problems, output solutions.

Limestone Technology Group builds AI-enabled applications and automation systems for real operational work. We help private businesses, state and local government, and regulated organizations improve the way work actually gets done — through custom applications, AI agents, workflow automation, integrations, cloud infrastructure, and managed operations.

We don't stop at the prototype. We map how the work happens, redesign the process, apply AI to the repetitive and information-heavy parts, build the software around the improved workflow, and then host, monitor, and continuously improve it in production. Our work is practical, production-focused, and measured by outcomes.

The Role

We're hiring a senior, hands-on Principal AI Applications & Cloud Engineer to build and operate AI-powered applications, agentic automation systems, integrations, and the AWS infrastructure underneath them.

You'll work across full-stack product development, AI agent design, cloud operations, and customer delivery. This is an early technical leadership role: you'll help define the engineering foundation of a growing AI automation company while shipping systems that solve real problems for real customers, usually in weeks rather than quarters.

What You'll Do

• Build full-stack web applications, customer portals, internal tools, dashboards, APIs, and integrations
• Design and implement AI agents and automation workflows that retrieve information, call tools, update systems, create tasks, draft responses, and route work for human approval
• Build document-processing, knowledge-access, case-management, and decision-support solutions
• Design the human-in-the-loop boundary deliberately — what AI may complete, what it prepares for approval, what stays fully human — with permissions, source evidence, audit history, and fallback behavior built in
• Design, deploy, secure, and operate AWS infrastruc
