NET Developer

NET Developer Location: 5 days onsite in Redmond, Washington (relocation is fine) Top Must-Have Skills 1) C# /.NET Development (6+ years) Strong, hands-on experience developing production systems using C# across.NET Framework and modern.NET (.NET Core /.NET 6+). Proven experience working on large or legacy codebases, including refactoring, modernizing projects, and improving code quality. Experience with SDK-style project migrations, NuGet package upgrades, and .NET runtime/framework upgrades. Ability to write maintainable, testable code and troubleshoot complex issues in service-oriented systems. 2) Cloud Services (4+ years) Hands-on experience building, deploying, and operating services in a cloud environment. Experience developing and maintaining RESTful Web APIs hosted in the cloud. Practical experience with cloud environments, including subscriptions, resource groups, and service configuration. Familiarity with cloud-based CI/CD workflows and platform upgrades impacting live services. 3) Infrastructure as Code & DevOps Foundations (3+ years) Strong experience defining and maintaining infrastructure using Infrastructure as Code (IaC) tools (e.g., ARM templates, Bicep, or Terraform). Experience upgrading or migrating build and deployment pipelines (Azure DevOps or equivalent). Understanding of infrastructure modernization efforts such as pipeline migrations, environment isolation, and platform compliance requirements. Proven ability to improve developer productivity by strengthening build reliability, test pipelines, and automation. Typical Day in the Role Design, develop, implement, test, and maintain business and computer applications software or specialized utility programs. Work on modernization of services, code base, and infrastructure, focusing on tasks related to business logic. Specific tasks include migrating project definitions to new standards, cleaning up source code warnings, upgrading NuGet packages, and modernizing old services to use updated authentication and authorization methods. Additional work may involve build pipeline migrations and infrastructure-level improvements, with a strong emphasis on C# and cloud experience, covering both.NET Framework and.NET Core. Gather and analyze system requirements, document specifications, and develop software solutions to meet client needs. Analyze and review enhancement requests and specifications. Implement system software and customize to client requirements. Prepare detailed software specifications and test plans. Code new programs to client's specifications and create test data for testing. Modify existing programs to new standards and conduct unit testing of developed programs. Create migration packages for system testing, user testing, and implementation. Provide quality assurance reviews. Perform post-implementation validation of software and resolve any bugs found during testing. Candidate Requirements Must have strong technical skills in C#,.NET, cloud services, and Infrastructure as Code. Excessive job hopping (e.g., changing jobs every month over the past two years) is considered a red flag. Prior experience with large-scale enterprise systems is preferred. Best vs. Average Candidate Experience splitting or migrating workloads to new repositories or isolated environments to reduce operational overhead. Exposure to large or legacy enterprise systems undergoing modernization. Experience improving test tooling or developer experience beyond pure feature delivery. Experience working in Agile/Scrum teams with two-week sprints. Ability to work independently on scoped technical initiatives while collaborating via code reviews and design discussions. Strong communication skills for working with full-time engineers, other vendors, and partner teams. Solid foundation in computer science, with strong competencies in data structures, algorithms, and software design. Large systems software design and development experience. Experience performing in-depth troubleshooting and unit testing with both new and legacy production systems. Core Technical Skills C# and.NET: Strong hands-on experience across.NET Framework and modern.NET (Core /.NET 6+). Cloud Application Development: Building and maintaining services in cloud environments, including hosted services and backend components. Infrastructure as Code: Hands-on experience defining and maintaining cloud infrastructure using IaC tools (ARM templates, Bicep, Terraform). Build, CI/CD, and Code Hygiene: Improving build pipelines, upgrading workflows, and ensuring code quality and maintainability. Testing and Reliability: Improving end-to-end test coverage, diagnosing workflow issues, and implementing test automation. Security Best Practices: Removing legacy authentication mechanisms and implementing secure identity and access patterns.
