NOTE: APPLICANT MUST BE ON OUR W2 OR 1099 AND CURRENT GA RESIDENT. C2C IS ALLOWED IF OWN CORPORATION ONLY. NOT ACCEPTING SUB-VENDORS.

Role:
Senior Full-Stack .NET Modernization Developer

Location:

Atlanta, GA - Hybrid Duration: 8 Months Interview: MS Teams or In-Person

DESCRIPTION:

WHAT THIS ROLE ACTUALLY IS:
  • Agency'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 Agency headquarters, Atlanta (subject to manager discretion)
  • Mandatory in-person:
    All Hands, Enterprise Applications meetings, Agency 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.
  • Design and implement scalable, secure, and maintainable application solutions that reduce 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 technologies.
  • Own the SQL Server platform, including data architecture, performance tuning, data migration, and platform modernization.
  • Implement and maintain CI/CD pipelines using Azure Dev Ops 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
  • Implement and maintain reporting using SSRS and Power BI
  • Participate in AI integration initiatives --- Azure Agentic AI services, Copilot tooling, and chatbot 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
  • Maintain application documentation, deployment runbooks, and user-facing guides
  • Participate in architecture reviews, code reviews, and sprint ceremonies
Required Qualifications:

EXPERIENCE:
  • 8 years of professional .NET development experience --- C#, ASP.NET MVC, Web API
  • Demonstrated, hands-on experience migrating legacy ASP.NET applications to modern .NET (6, 7, 8 or 10) --- not just exposure
  • Production SQL Server experience: stored procedures, T-SQL tuning, schema migrations, data cleanup
  • Azure hands-on:
    App Services, Function Apps, deployment pipelines, configuration management
  • 5 years delivering software in Agile (Scrum or Kanban) environments using ADO or Git Hub
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
