Senior Full-Stack .NET Modernization Developer

Job: Senior Full-Stack .NET Modernization Developer

Job ID: 812436

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

Client : State of GA

Hybrid Role: Tuesday Thursday on-site

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 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. .

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

You have modernized a real application - not a proof of concept - from legacy ASP.NET

to .NET 6/7/8/10

You have designed and maintained RESTful APIs that external systems depend on

You have debugged production issues independently, without a team lead walking you through it

candidates.

applications

Experience with middleware platforms such as Boomi or MuleSoft

Background working with PII data and the security protocols that protect it

Education

Bachelor's degree in Computer Science, Information Technology, or a related field - or

equivalent work experience that demonstrates the same depth

What We Value Beyond the Technical

This team works on systems that affect real families in Georgia. We move fast because the mission

requires it, but we do not cut corners on security, accessibility, or data integrity.

Ownership: You finish what you start and you tell people early when something is at risk

Directness: You surface problems with a proposed fix, not just a flag

Clarity under pressure: You can explain a technical constraint to a non-technical stakeholder

without condescending or drowning them in jargon

Adaptability: Government systems change scope. Requirements shift. You adjust without drama
