Senior Full-Stack .NET Modernization Developer
2 M.L.K. Jr Dr SE #754, Atlanta, GA 30334
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. .
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

deployment, and release management.
Drive engineering excellence through code reviews, automation, documentation, and
adherence to modern development practices.

WHAT HANDS-ON MEANS HERE
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
Preferred Qualifications
These will make you effective faster. They are not dealbreakers, but they distinguish competitive
candidates.
React experience specifically building components within an existing application, not greenfield
Exposer to .NET 10
Power BI or SSRS reporting development
Experience with government, healthcare, or public-sector systems you understand
compliance, auditability, and data sensitivity

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
