    What This Role Actually Is
    DECAL'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. .

    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.
    F rontend & 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
    About DECAL

    make those programs run.
    This role directly supports the core licensing platform at the center of provider licensing and eligibility.
