We are looking for a Senior Full-Stack C#/.NET Engineer to support the development of a prototype based on an existing monolithic .NET system in the insurance domain. The project involves forking an existing backend and UI codebase, addressing architectural gaps, implementing new policy-related functionality, and preparing the solution for deployment in a sandboxed cloud environment.

• Ensure the application is fully deployable and functioning end-to-end in a cloud environment (Azure).
• Collaborate directly with product/domain stakeholders to refine technical requirements.
• Work with the internal team to configure infrastructure, deployment pipelines, and database dependencies.
• Troubleshoot and resolve issues in the legacy codebase as part of PoC development.

WHO YOU ARE

• 5+ years of experience with C#/.NET development.
• Strong expertise in monolithic architecture, backend refactoring, and legacy system modernization.
• Hands-on experience with Razor Pages, and MS SQL.
• Ability to independently deliver functional prototypes in compressed timelines.
• Experience deploying .NET applications to Azure or similar cloud platforms.
• Strong communication skills and ability to work directly with non-technical stakeholders.

NICE TO HAVE
