Job Summary:

As a Blazor Developer, you will be responsible for developing dynamic and interactive web applications using Blazor Server. You will work closely with the backend and UI/UX teams to build seamless, scalable, and high-performing applications.

Key Responsibilities:

• Core Blazor Server Development
  • Design and implement Blazor Server components using Razor, ensuring optimal state management and minimal re-renders.
  • Handle SignalR-based circuit management, real-time updates, and reconnection logic to maintain robust user sessions.
• Reusable Component Architecture
  • Create modular, reusable, and maintainable Blazor components for common UI elements and data interactions.
  • Adhere to SOLID principles and design patterns, promoting clean architecture and code reusability.
• Integration with gRPC Services
  • Connect Blazor Server components to gRPC endpoints for data retrieval, processing, and event notifications.
  • Troubleshoot serialization, streaming, and performance issues related to gRPC integration.
• Advanced .NET 9 & C# Expertise
  • Utilize .NET 9 features (e.g., enhanced pattern matching, records, improved generics) for efficient and readable code.
  • Apply object-oriented programming concepts and SOLID design principles to ensure scalability and maintainability.
• Performance Optimization
  • Ensure high performance by optimizing rendering, data loading, and concurrency models.
  • Use asynchronous programming (async/await) and parallel processing where appropriate to enhance responsiveness.
• Security & Identity
  • Implement secure user authentication and authorization (e.g., OpenID Connect, role-based access).
  • Follow best practices for data protection, encryption, and handling of sensitive information in a multi-tenant SaaS environment.
• UI/UX Considerations
  • Collaborate with design teams to build responsive and intuitive interfaces.
  • Utilize HTML5, CSS3, and basic JavaScript/TypeScript to augment Blazor where necessary.
• Debugging & Testing
  • Diagnose and resolve complex issues using Visual Studio, browser dev tools, and logging frameworks.
  • Write unit, integration, or end-to-end tests to ensure robustness and quality of new and existing features.
• Collaboration & Agile Processes
  • Work in an Agile/Scrum environment, participating in sprint planning, daily standups, and retrospectives.
  • Collaborate closely with product owners, QA teams, and fellow developers to meet delivery timelines and quality standards.

Required Skills & Qualifications:

• Proven Experience with Blazor Server
  • Demonstrated success in building production-ready Blazor Server applications, focusing on real-time data handling.
  • Familiarity with Razor Components, data binding, and state management best practices.
• Strong C# & OOP Fundamentals
  • Expertise in .NET 9 development, including advanced features of C#.
  • Solid grasp of object-oriented principles, design patterns, and SOLID best practices.
• Proficiency in Integrating with gRPC
  • Understanding of protocol buffers, client code generation, and best practices for microservice communication.
  • Ability to diagnose and fix issues related to gRPC calls, streaming data, and performance.
• SignalR & Real-Time Communication
  • Hands-on experience with SignalR for server-client updates and reliability in Blazor Server apps.
• Security & Authorization
  • Practical knowledge of authentication/authorization in .NET (e.g., Identity, OAuth, OpenID Connect).
  • Capability to implement role-based access control and protect common web vulnerabilities (XSS, CSRF, etc.).
• Performance Optimization & Debugging
  • Proficiency in identifying performance bottlenecks in server-side rendering, data fetching, and concurrency.
  • Skilled in using debugging tools, performance profilers, and diagnostics to optimize application speed and reliability.
• Effective Communication & Teamwork
  • Strong interpersonal skills for cross-functional collaboration.
  • Clear verbal and written communication skills, with a willingness to provide and receive constructive feedback.

Preferred Qualifications:

• Experience with containerization (Docker/Kubernetes) and CI/CD pipelines.
• Knowledge of ERP domains (finance, inventory, HR, etc.).
