Software Developer in Test

The Software Developer in Test is responsible for owning quality across multiple interconnected C# platforms, ensuring software is reliable, testable, and regression-safe at every layer of the stack. This role operates within an established testing pyramid spanning unit, integration, and regression coverage across a server-side service layer and a thick-client installer-distributed application, while driving maturity in both as the platform evolves. The ideal candidate brings hands-on experience in .NET/C# environments and a systematic approach to test architecture, enabling them to contribute meaningfully to both test strategy and day-to-day implementation.

Responsibilities

• Write and maintain NUnit unit and integration tests for C# service and application layers - covering backend service domains (Auth, Device, Session) and desktop application components (configuration, application lifecycle, authentication adapters)
• Demonstrate working knowledge of the full development stack, including WPF, MVVM, DI, WCF/SOAP and REST/WebAPI
• Test WCF/SOAP service contracts and REST/WebAPI endpoints for correctness and schema compliance
• Validate desktop application behaviors, executable resolution, launch configuration, and environment-specific config correctness across Dev, QA, and Production
• Validate SignalR real-time messaging behavior
• Build and execute integration tests against partner API surfaces (NetSuite and others)
• Author and maintain automated tests within Azure Pipelines, write pipeline YAML steps, monitor VSTest results, investigate build failures, and maintain test discovery patterns
• Test across multi-environment build configurations and verify config-transform and accuracy
• Collaborate with developers on service-layer and application-layer mocking strategies using MOQ and identify gaps in unit test coverage
• Triage production defects and reproduce them in isolated integration test scenarios
• Write and maintain testing SOPs, document test plans, test case procedures, environment setup guides, and regression runbooks for use across the team
