Job Description:

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 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
• 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
  • 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
