DECAL Senior Full-Stack .NET Modernization Developer

Role: DECAL Senior Full-Stack .NET Modernization Developer 

Location: 2 M.L.K. Jr Dr SE #754, Atlanta, GA 30334

Duration: 12 Months

Client: Nanda Technologies

End Client: State of GA

Mode of Work: Hybrid

 

Description:

Under general supervision, designs, codes, tests, modifies and debugs computer software.

 

What This Role Actually Is 

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  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. . 

 

Work Location 

• Must be physically located in Georgia 

• Hybrid: Tuesday–Thursday on-site at DECAL headquarters, Atlanta (subject to manager 

discretion)
