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) 

• Mandatory in-person: All Hands, Enterprise Applications meetings, DECAL All Staff, and 

designated on-site milestones

What You Will Do 

Application Modernization (Core of this Role) 

• Champion the modernization of DECAL's mission-critical licensing and eligibility applications, 

transitioning legacy solutions to modern .NET and Azure-based architectures.

technical debt and improve long-term supportability. 

• Build and evolve API-first integrations and services that enable future platform capabilities. 

• Develop cloud-native solutions using Azure App Services, Azure Functions, and related Azure

• Own the SQL Server platform, including data architecture, performance tuning, data

• Implement and maintain CI/CD pipelines using Azure DevOps to automate testing, 

deployment, and release management. 

• Drive engineering excellence through code reviews, automation, documentation, and 

adherence to modern development practices. 

Frontend & Integration 

• Build and maintain React-based UI components as part of the modernization roadmap 

• Demonstrate a strong understanding of web application rendering patterns, including client

side rendering (CSR), server-side rendering (SSR), component-based architectures, and 

modern frontend frameworks. 

• Integrate third-party services and internal APIs; document every integration cleanly

integrations where applicable 

Quality, Documentation & Support 

• Write code that your teammates can read and maintain six months from now 

• Provide production support and own root-cause analysis when things break

Required Qualifications 

EXPERIENCE 

• 8 years of professional .NET development experience — C#,  MVC, Web API
