Net Web Api Developer information

What is a .NET Web API developer?

A .NET Web API Developer is a software engineer who specializes in building and maintaining web APIs using Microsoft's .NET framework. These APIs enable different software systems to communicate over the web, often supporting front-end applications or mobile apps. The developer is responsible for designing, developing, testing, and deploying RESTful services that are secure, efficient, and scalable. They often work with technologies like C#, ASP.NET Core, and Entity Framework, and are skilled in integrating various data sources and services.

What are the key skills and qualifications needed to thrive as a .NET Web API developer?

To thrive as a .NET Web API Developer, you need solid programming skills in C#, experience with ASP.NET Core, and a good understanding of RESTful API design, typically supported by a degree in computer science or related field. Familiarity with development tools such as Visual Studio, version control systems like Git, and knowledge of cloud platforms (e.g., Azure) or certifications in .NET technologies are highly beneficial. Strong problem-solving abilities, effective communication, and the ability to work collaboratively make a developer stand out in this role. These skills ensure the creation of robust, scalable, and maintainable web services that meet business and user needs.

What are the most common challenges a .NET Web API developer faces when integrating APIs with front-end applications?

One of the most common challenges .NET Web API Developers encounter is ensuring seamless communication between the back-end APIs and diverse front-end frameworks. Issues such as handling CORS, authentication, consistent data formatting, and version control can arise during integration. Developers also need to coordinate closely with front-end teams to clarify API specifications and troubleshoot integration bugs. Proactive documentation, regular communication, and thorough testing are essential strategies to overcome these challenges, ensuring a smoother development workflow.

What is the difference between Net Web Api Developer vs ASP.NET Developer?

AspectNet Web Api DeveloperASP.NET Developer
Primary FocusDesigning and developing Web APIs for data exchangeBuilding web applications using ASP.NET framework
Required SkillsWeb API, C#, .NET, REST, JSONASP.NET, C#, MVC, Razor, Web Forms
Work EnvironmentBackend API development, server-side logicFull-stack or web application development
Common UsageCreating services for mobile apps, integrationsDeveloping enterprise web applications

While both roles involve .NET technologies, a Net Web Api Developer specializes in creating APIs for data exchange, whereas an ASP.NET Developer focuses on building complete web applications using ASP.NET frameworks. The roles often overlap but differ mainly in scope and primary responsibilities.

Are Net Web API developers in demand?

Net Web API developers are in high demand due to the widespread use of web services and cloud-based applications. Skills in C#, .NET framework, and RESTful API design are particularly valuable, and demand is expected to grow as businesses continue to develop scalable, secure web APIs. The role often requires knowledge of related technologies like SQL, Azure, and security protocols.

Senior .NET Developer – CSMS (Child Support Management System)

Job Summary:
We are seeking an experienced Senior .NET Developer to join the CSMS modernization team. You will design, develop, and maintain mission-critical microservices and applications that support child support case management operations. The role requires strong experience in microservices architecture — building, deploying, and maintaining loosely coupled, independently deployable services. Your work will span web application development, REST API services, batch processing, and system integrations within a cloud-native environment.
Consultants may be eligible to telecommute for more than 50% of their work hours, up to and including 100% remote work. Telecommuting arrangements require direct manager approval and are subject to change based on program needs. Consultants approved for 100% remote work must attend monthly in-person meetings at the Albany office and be available for major milestone meetings as needed.
Key Responsibilities:
  • Design, develop, and maintain microservices using ASP.NET Core, following domain-driven design and service decomposition best practices
  • Build and deploy loosely coupled, independently deployable services with well-defined API contracts
  • Develop scalable web applications, RESTful APIs, background/worker services, and integration services for the application platform
  • Develop and optimize batch and scheduled jobs (Hangfire, Quartz.NET, or Azure Functions) for high-volume data processing, reporting, and scheduled workflows
  • Implement data access layers using Entity Framework Core against SQL Server or PostgreSQL databases
  • Manage inter-service communication patterns including synchronous REST calls and asynchronous messaging
  • Collaborate with architects and business analysts to translate requirements into technical solutions
  • Participate in code reviews, enforce coding standards, and mentor junior developers
  • Troubleshoot application issues and provide timely resolutions across distributed microservices
  • Contribute to CI/CD pipeline improvements and deployment automation for microservices
  • Write unit and integration tests to ensure code quality and reliability
  • Work with cross-functional teams on system integration efforts including third-party and inter-agency data exchanges
Mandatory Qualifications:
  • 7+ years of professional .NET development experience
  • Strong proficiency in C# and .NET 8 (records, pattern matching, async/await, minimal APIs, latest language features)
  • Proven experience designing and building microservices architectures — service decomposition, API gateway patterns, service discovery, and distributed configuration
  • Extensive experience with ASP.NET Core and the .NET ecosystem (Web API, MVC, dependency injection, middleware, Identity)
  • Hands-on experience with batch/background processing frameworks (Hangfire, Quartz.NET, or Azure Functions) for large-scale processing
  • Solid understanding of Entity Framework Core for ORM and database interaction
  • Experience with SQL Server, PostgreSQL, or similar relational databases
  • Proven track record of building and consuming RESTful APIs with proper versioning and contract-first design
  • Experience with inter-service communication patterns (REST, messaging queues, event-driven)
  • Experience deploying and operating microservices on Azure (App Service, AKS, Azure SQL, Blob Storage, Service Bus, Azure Functions) or AWS equivalents
  • Familiarity with CI/CD tools (Azure DevOps, GitHub Actions, Jenkins, or similar) for microservices deployment pipelines
  • Strong understanding of software design patterns, SOLID principles, and clean code practices
  • Experience with Git version control and collaborative development workflows
  • Understanding of distributed system concerns: fault tolerance, circuit breakers, retries, and observability
Desirable Qualifications:
  • Experience with government or public sector projects
  • Hands-on experience with microservices patterns such as saga, CQRS, event sourcing, and API composition
  • Familiarity with service mesh technologies
  • Experience with containerization (Docker) and orchestration (Kubernetes/AKS) for microservices deployment
  • Knowledge of message-driven architecture (Azure Service Bus, RabbitMQ, Kafka) for asynchronous inter-service communication
  • Knowledge of API gateway solutions (Azure API Management, Ocelot, YARP)
  • Experience with centralized logging and distributed tracing across microservices (Application Insights, Serilog, Splunk, Datadog, OpenTelemetry)
  • Knowledge of infrastructure-as-code (Terraform, Bicep, ARM templates)
  • Understanding of OAuth2/OpenID Connect for securing microservices (Azure AD / Entra ID, IdentityServer, Duende)
  • Knowledge of database-per-service patterns and database migration tools (EF Core Migrations, FluentMigrator, etc.)

Flexible work from home options available.
