Job description

**Role overview**

A senior front-end engineering role centered on modernizing an existing web portal into a refreshed Blazor-based experience. The position blends UI component development, design translation, and tight collaboration with back-end and design partners to deliver a polished, maintainable product.

**Responsibilities**

• Partner with product owners, UX, and design teams to convert a legacy portal into a modern interface built with C# and Blazor, updating layouts, components, and user flows.
• Develop front-end features primarily through a commercial Blazor UI component library (Syncfusion Blazor).
• Build, test, and debug the UI in Visual Studio 2026 as the primary development environment.
• Author and run API request and response tests using Postman or similar tooling to validate front-end to back-end connectivity.
• Translate design and UX changes into concrete technical scope, including responsive behavior, data bindings, state management, and reusable component configuration.
• Participate in code reviews, contribute to the shared UI component library and coding standards, and mentor more junior UI developers.

**Requirements**

• Senior-level experience building production front-end applications with C# and Blazor.
• Practical experience with at least one Blazor UI component library, ideally Syncfusion Blazor.
• Confidence using Visual Studio (2026) as a daily IDE for building, debugging, and testing.
• Comfort designing component APIs, managing state, and integrating front-end code against REST or similar back-end APIs.
• Strong eye for responsive layout, interaction details, and overall UI quality.
• Experience working in a distributed, asynchronous team with shifting priorities and limited hierarchy.

**Nice to have**

• Exposure to Postman or comparable API testing tools.
• Prior involvement in modernizing a legacy portal or product surface rather than building greenfield only.
