SQA Engineer

A Software Quality Assurance Engineer with strong scripting skills and a solid software development background to support testing across a modern full‑stack ecosystem that includes .NET, Blazor, SignalR, REST APIs, microservices, and cloud‑hosted backend systems. This role ensures the reliability, performance, and security of both UI‑heavy web applications and backend imaging workflows used in clinical environments. The ideal candidate has experience validating distributed systems, real‑time communication features, and high‑volume data workflows, with a strong focus on automation, traceability, and compliance‑sensitive testing.

Key Responsibilities

• Develop and maintain automated test suites for UI, API, backend services, and microservices using scripting languages or C#‑based test frameworks
• Design and execute test plans covering full‑stack workflows, including Blazor UI, REST APIs, SignalR real‑time communication, and backend imaging services
• Validate real‑time features such as study/series loading updates, viewer synchronization, and workflow notifications
• Test backend business logic for study, series, and image metadata management
• Validate database operations, schema changes, and data integrity across SQL Server and related storage systems
• Test authentication and authorization flows (role‑based access, JWT, identity systems)
• Evaluate system performance, concurrency behavior, and reliability under high‑volume imaging workloads
• Test cloud‑hosted services, containerized components, and microservice interactions (AWS or similar)
• Build and maintain test harnesses, mocks, and tools to support backend and distributed system testing
• Integrate automated tests into CI/CD pipelines and monitor quality gates
• Investigate, document, and track defects; verify fixes and perform regression testing across the stack
• Validate deployments, perform smoke tests, and support production troubleshooting
• Ensure testing practices align with healthcare security, privacy, and compliance requirements

Required Qualifications

• 3–6 years of professional experience in software QA, test automation, or software development
• Strong scripting skills (PowerShell, Python, JavaScript, or similar)
• Solid understanding of C#/.NET and modern backend development principles
• Experience testing RESTful APIs, backend services, and distributed systems
• Experience validating real‑time communication features (SignalR or equivalent)
• Familiarity with SQL Server, relational data modeling, and data validation
• Experience testing cloud‑hosted applications or microservices (AWS preferred)
• Understanding of secure application development and testing practices
• Experience with Git and modern team‑based workflows
• Ability to write clear test cases, test plans, and defect reports

Preferred Qualifications

• Experience testing Blazor applications (Server or WebAssembly)
• Experience with automated UI testing frameworks (Playwright, Selenium, Cypress)
• Familiarity with component libraries (MudBlazor, FluentUI)
• Experience with performance/load testing tools (JMeter, k6)
• Experience testing containerized applications (Docker)
• Knowledge of logging, monitoring, and audit trails in regulated environments
• Experience with AWS‑based healthcare systems or cloud‑native architectures

Desired Attributes

• Strong attention to reliability, data integrity, and workflow correctness
• Ability to test complex, distributed, and compliance‑sensitive systems
• Strong analytical and debugging skills across UI, backend, and cloud layers
• Effective communication and collaboration skills
• Commitment to maintainable, repeatable, and automation‑driven testing
• Experience in medical imaging or healthcare applications
• Familiarity with DICOM concepts (Study, Series, SOP Instances)
• Experience validating integrations with PACS or imaging storage systems
