Senior Full-Stack .NET Modernization Developer
Client core licensing platform is a mission-critical application that supports child care licensing, provider management, and program eligibility across the State of Georgia. We are in the middle of a major modernization effort, moving from a legacy ASP.NET architecture to .NET 8+, modern APIs, Azure cloud services, and a React-based user experience. This is not a maintenance or production support role. This position is for a senior engineer who wants to lead modernization efforts, solve complex technical problems, and help shape the future architecture of a statewide platform. You will play a key role in technical design decisions, application architecture, cloud integration, and delivery. Our team is intentionally lean. That means ownership matters. You will be expected to take a solution from concept to production, including design, development, testing, deployment, documentation, and operational support. Success in this role requires initiative, accountability, and the ability to work independently.
