Software Application Developer – Application Modernization

Position Summary
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.

 

Technical Skills & Qualifications

 

Required

·       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.

·       Handson experience with SSIS or similar ETL tooling and coordinating application-side integration with ETL processes.

·       Prior experience modernizing legacy .NET Framework applications in public-sector or enterprise contexts.

·       Familiarity with Windows services, scheduled tasks, or job schedulers used to run background processing.

·       Experience with application logging/telemetry and operational runbooks.

·       Knowledge of security/access controls for enterprise applications and data handling best practices.

·       Exposure to accessibility (WCAG) and cross-browser compatibility testing.

 

Key Deliverables

·       Implemented user stories with server and UI components.

·       Technical design documents, UI mapping, and runbooks for operational support.

·       Database schema updates, stored procedures, and performance tuning changes.

·       SSIS/ETL coordination artifacts and integration test results.

·       Unit/integration test artifacts and CI pipeline results in Azure DevOps.

·       Deployment artifacts, pipeline definitions, and rollback/runbook documentation.

·       Status reports, defect logs, and knowledge transfer materials.
