• Actual Job Title 812436 - DECAL Senior Full-Stack .NET Modernization Developer
• Job Type FT Contract
• Date Opened 09/22/2026
• Target Date 09/28/2026

• Assigned Recruiter(s) Dinesh Mathi
• Number of Positions 1

DECAL's 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.
If you're looking for a highly structured environment where work is narrowly defined and tasks are
handed to you step-by-step, this is probably not the right fit. If you enjoy building, leading, and
owning outcomes, you'll thrive here. .
