  The Office of Early Childhood (OEC) is hiring a Software Application Developer to implement and maintain server side and UI components as part of a legacy-to-modernization effort. The project targets .NET Framework 4.8 and uses Visual Studio 2022 for development.  This is a hybrid position requiring 2 in office days.
• This role focuses on fullstack application development (server and UI), database integration, ETL/SSIS collaboration, performance and security hardening, and CI/CD support within an Agile Scrum team. Integrations are implemented via direct database access, SSIS/ETL, file interfaces, and scheduled jobs.

Key Responsibilities:

• Requirements Analysis & Documentation
• Collaborate with product owners, business stakeholders, and architects to elicit, analyze, and document technical and functional requirements.
• Translate business requirements into developer tasks, acceptance criteria, and Azure DevOps work items.
• Produce and maintain technical design notes, screen/interface mappings, and operational runbooks.

Application Development & Implementation

• Design, implement, and refactor serverside components using C# and ASP.NET MVC targeting .NET Framework 4.8.
• Build and maintain Razor views and client behaviors using HTML5, CSS3, JavaScript, jQuery, and Bootstrap.
• Implement business logic, background jobs, scheduled tasks (Windows services / Task Scheduler), and server-side processing without introducing API layers.
• Use Entity Framework or ADO.NET and stored procedures for direct database access and transactional logic.
• Participate in code reviews and enforce coding standards, security, and maintainability best practices.

Database, Integration & ETL Collaboration

• Work with Azure SQL / SQL Server schema, stored procedures, indexing and performance tuning.
• Collaborate with data engineers on SSIS packages, ETL processes, and file-based interfaces; validate integration points and data flows.
• Implement data access patterns that support migration validation and referential integrity checks.

Quality, Performance & Security

• Profile and resolve performance issues; implement caching, batching, and asynchronous processing where appropriate.
• Apply secure coding practices; implement authentication/authorization used by the project (Windows auth, Forms auth, or Azure AD as applicable).
• Assist with operational support: logging, monitoring, diagnostics and incident response runbooks.

DevOps & Release Management

• Contribute to CI/CD pipeline definitions and maintenance in Azure DevOps (builds, tests, packaging, deployments).
• Produce deployment artifacts and support automated deployments to test, staging, and production environments.
• Maintain deployment documentation and rollback plans.

Agile/Scrum Collaboration

• Participate in all Scrum ceremonies (daily standups, sprint planning, reviews, retrospectives).
• Collaborate closely with QA, data migration specialists, and business SMEs to deliver sprint goals.

• Strong professional experience with C# and .NET Framework 4.8 (ASP.NET MVC, Razor views).
• Experience with Entity Framework and/or ADO.NET, T-SQL, stored procedures, and query performance tuning on SQL Server / Azure SQL.
• Proficiency with front-end technologies used by the project: HTML5, CSS3, JavaScript, jQuery, Bootstrap.
• Practical experience with Azure DevOps: Git source control, build/release pipelines, work item and test management.
• Familiarity with Visual Studio 2022 for day-to-day development and debugging.
• Strong troubleshooting skills and experience resolving production defects and performance issues.
• Preferred

·          Experience with unit and integration testing frameworks and test automation.
