IT Senior Full-Stack .NET Modernization Developer (GA812436)

IT Senior Full-Stack .NET Modernization Developer (GA812436)

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
