Senior .Net Developer

We are looking for a Senior .Net Developer. This is full time hybrid nine (9+) plus months contract position with our client in Raleigh, North Carolina. In this role as a Senior .Net Developer you will be converting a legacy Classic ASP application into a modern .NET 10 architecture, rebuilding a large, business-critical web application into multiple web portals supported by REST APIs and a SQL Server backend.

A key aspect of this role is working with legacy, third-party code that is not always well documented. Because of this, we are looking for someone who is comfortable operating in ambiguity, can interpret existing behavior, and make informed decisions on how to modernize functionality while maintaining business continuity.

Responsibilities as a Senior .Net Developer:

• Upgrade and modernize a large Classic ASP website into a modern architecture
• Convert the existing application into three web applications and two APIs
• Migrate functionality from Classic ASP to C# / .NET 10
• Build and support policyholder portal features and administrative access management
• Work closely with Scrum teams and technical stakeholders
• Collaborate primarily with the technical team; limited direct business interaction
• Prepare the application for hosting in the cloud (AWS or Azure)
• Support knowledge transfer to the maintaining vendor post-upgrade

Required skills and qualifications as a Senior .Net Developer:

• 9+ years of hands-on experience with .NET (C#), building REST APIs, and working with SQL Server and Entity Framework Core
• Hands on experience modernizing or working within legacy systems (e.g., Classic ASP or similar architectures)
• Experience working with both frontend (Razor Pages, JavaScript/jQuery) and backend components
• Collaborating with existing team members rather than duplicating discovery efforts
• Works independently and takes ownership of problems, while still collaborating effectively with others
• Brings forward recommendations and trade-offs, not just questions or blockers
• Communicates clearly and can align with team direction while contributing their own ideas
