Responsibilities
- Maintain and enhance UIs built with jQuery, Kendo UI, Bootstrap, and lead upgrades (jQuery → 3.7, Bootstrap 3 → 5, Kendo UI updates, and gradual migration to Angular + TypeScript).
- Build responsive, accessible interfaces (WCAG 2.1 AA).
- Develop backend services across multiple .NET layers; build/consume REST APIs in ASP.NET / ASP.NET Core.
- Write clean, maintainable C# following SOLID and clean architecture; refactor legacy code safely.
- Implement automated tests (xUnit / NUnit) and maintain strong regression coverage.
- Work with Entity Framework, ADO.NET, and design efficient SQL Server schemas, queries, and stored procedures.
- Support integrations (QuickBooks, Magick.NET, log4net, JWT auth, XML signing, BouncyCastle, WebDAV).
- Drive security and dependency remediation (SCA scans, CVE triage, package upgrades).
- Contribute to the .NET Framework → .NET 8/10+ migration
Requirements
- 5+ years building production .NET applications — strong command of C# and the .NET ecosystem (Framework & Core).
- Hands-on experience with ASP.NET / ASP.NET Core Web API and designing RESTful services.
- Solid experience with SQL Server — schema design, T-SQL, stored procedures, indexing, and query optimization.
- Proficient in JavaScript / TypeScript with hands-on experience in jQuery-based applications and component libraries such as Kendo UI and Bootstrap.
- Experience or strong interest in modern UI frameworks (Angular preferred).
- Strong understanding of SOLID, clean architecture, separation of concerns, and dependency injection.
- Experience with automated testing frameworks (xUnit / NUnit / MSTest; Jest or Jasmine on the front end).
- Familiarity with secure coding practices and OWASP Top 10; ability to triage and remediate CVEs from SCA tools.
- Comfortable working in a long-lived codebase using legacy patterns (packages.config, Web Forms, jQuery) while incrementally modernizing.
- Experience with Git, pull-request review workflows, and CI/CD pipelines.
- Strong problem-solving skills, debugging discipline, and ability to work in an agile, collaborative environment.
- Excellent written and verbal communication — able to document decisions and explain technical trade-offs to non-engineers.
