Blazor C# Developer

Blazor C# Developer
Walnut Creek, CA - Remote

We are seeking a Full-Stack Software Engineer with strong .NET fundamentals to build and scale data-dense web applications for public health and operational teams. This role is highly focused on modern Microsoft technologies, requiring a developer who can build interactive web UIs using Blazor (Server/WebAssembly) and develop robust, high-performance backend services and Web APIs using C# .
While the platform processes geospatial data, this is an engineering-first position rather than a GIS role. You will own features end-to-end across the stack-leveraging Entity Framework, SQL Server, and Azure cloud services -to deliver performant, data-driven workflows and clean user experiences. This role starts as a 3-month contract with a clear path to full-time employment.


Here is that section reformatted with clean typography, bolded action verbs, and professional bullet points to make it much easier to scan:

• Build and maintain backend services and APIs to support map interactions and data access
• Refactor blazor components
• Collaborate closely with product and design to translate real-world workflows into intuitive UI patterns
• Ensure performance , usability, and clarity when working with large or complex data sets
• Iterate quickly based on user feedback and evolving requirements
• Contribute to a collaborative, pragmatic engineering culture focused on building the right solution, not just shipping code

Required

• C# / .NET: Minimum 3 years of experience building production applications
• Blazor: Hands-on experience building interactive web UIs with Blazor (Server and/or WebAssembly)
• SQL Server & Entity Framework: Required experience for designing, querying, and maintaining data-driven applications
• Azure: Experience integrating and managing Azure services to support scalable, cloud-based applications
• Full-Stack Ownership: Comfort working across the stack and owning features end-to-end
• Data Visualization: Ability to reason about data visualization and user interaction, especially in data-dense interfaces

Nice to Have

• Frontend Development: Recent, hands-on experience with JavaScript and modern frontend development
• User-Centric Design: Experience building applications used by operational or non-technical users
• Performance Tuning: Exposure to performance optimization in data-heavy applications
