We are seeking a .NET Developer who will 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 role focuses on full stack 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 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.

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

• 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.

• 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.
