Role Overview :

We are hiring a Senior .NET Full Stack Engineer who can design, build, and ship enterprise-grade web applications using C#, ASP.NET Core, SQL Server, and modern front-end frameworks (React/Angular).

You will work closely with product owners, architects, QA, and DevOps to deliver features end-to-end, modernize legacy .NET applications to .NET 8, and ensure reliability, security, and maintainability.

Key Responsibilities :

- Solution & Architecture : Translate business requirements into technical designs using Clean Architecture, SOLID principles, and design patterns.

- Contribute to microservices or modular monolith architectures as appropriate.

- Backend Development : Build RESTful (and optional GraphQL/gRPC) services with ASP.NET Core (.NET 6/7/8), implement business logic, validation, caching, and logging (Serilog).

- Create OpenAPI/Swagger specs and secure APIs with OAuth2/OIDC (Azure AD), JWT.

- Database & Data Layer : Design schemas, write complex T-SQL, stored procedures, functions, indexing strategies, and perform query optimization on SQL Server 2019/2022.

- Implement data access via EF Core and/or Dapper.

- Frontend Development : Build responsive, accessible UI using TypeScript with React 18+ (Redux/RTK/Query) or Angular 15+ (RxJS/NgRx), HTML5/CSS3 (Tailwind/Bootstrap).

- Follow WCAG 2.1 AA accessibility guidelines.

- Quality Engineering : Write unit/integration tests (xUnit/nUnit, Moq), participate in code reviews, maintain code quality via SonarQube/linters, and support test automation with QA (Playwright/Cypress/Postman collections).

- Performance & Observability : Profile APIs/queries, implement caching (Redis), asynchronous processing, and telemetry (OpenTelemetry, Application Insights).

- Establish SLOs/SLIs and error budgets where relevant.

- Cloud & DevOps : Deploy and operate apps on Azure (App Service, Azure SQL, Storage, Key Vault, Functions, Service Bus) or equivalent AWS/GCP.

- Build CI/CD pipelines (Azure DevOps/GitHub Actions), containerize with Docker, and use IaC (Bicep/Terraform) as needed.

- Security & Compliance : Adhere to OWASP Top 10, secrets management, secure coding standards, and data privacy expectations (incl. DPDP/GDPR where applicable).

- Agile Collaboration : Work in Scrum/Kanban; participate in grooming, estimation, sprint reviews; demo features to clients; contribute to reusable components and engineering playbooks.

- Legacy Modernization : Assess .NET Framework apps and plan migration to .NET 8, improving performance, reliability, and cost efficiency.

Required Skills & Experience :

- 6-8 years of hands-on experience building enterprise web applications with C# and ASP.NET Core (preferably .NET 6+, ideally .NET 8).

- Strong expertise in SQL Server : schema design, T-SQL, performance tuning (execution plans, indexing, partitioning), and transaction/isolation concepts.

- Proficiency in a modern front-end framework : React or Angular; strong TypeScript, component-driven development, and state management.

- Practical knowledge of Entity Framework Core and Dapper, LINQ, and repository/unit-of-work patterns where appropriate.

- Experience designing and consuming REST APIs, OpenAPI/Swagger, Postman; understanding of HTTP, CORS, caching, pagination, idempotency.

- Exposure to Azure services (App Service, Azure SQL, Key Vault, Storage, Service Bus) and CI/CD with Azure DevOps or GitHub Actions.

- Familiarity with Docker, containerized local dev, and environment configuration.

- Strong debugging skills and performance mindset; comfort with tools like dotnet-trace, PerfView, or SQL Profiler.

- Excellent communication and stakeholder management; ability to mentor junior engineers.

Nice-to-Have :

- Blazor or micro-frontend experience; real-time apps with SignalR.

- gRPC or GraphQL (Hot Chocolate) in .NET.

- Messaging/event-driven systems (Azure Service Bus, RabbitMQ, Kafka), CQRS, and event sourcing.

- Redis/ElasticSearch for caching/search; SSRS/Power BI embedding for reporting.
