Full Job Description
NOTE:
  • Local to Atlanta, GA
  • Hybrid is required


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

Complete Description:

What This Role Actually Is
  • DECAL's core licensing platform is a mission-critical application that supports childcare 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
  • 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
  • Own the SQL Server platform, including data architecture, performance tuning, data migration, and platform modernization.
  • 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
  • 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 GitHub


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
  • 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
  • Familiarity with ADA/WCAG 2.1 AA accessibility standards
  • Exposure to Azure Agentic AI services or integration of AI-driven features in production 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
