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.

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.

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.
