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 

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
