Validate real-time features such as:

Study/series loading updates

Viewer synchronization

Notifications and workflow events

Validate asynchronous processing, concurrency handling, race conditions, and distributed transaction behaviors

Test backend business logic supporting study, series, and image metadata management

Validate database operations, schema changes, relational integrity, and backend data consistency across SQL Server, Postgres, and related storage systems

Test authentication and authorization flows including role-based access, JWT authentication, and identity systems

Evaluate system performance, scalability, concurrency behavior, and reliability under high-volume imaging workloads

Test cloud-hosted services, containerized applications, and distributed microservice interactions (AWS preferred)

Build and maintain test harnesses, mocks, utilities, and automation tools supporting backend and distributed system testing

Analyze backend logs, API traces, service interactions, and monitoring data to isolate defects and support troubleshooting

Validate logging, audit trails, monitoring behavior, and observability mechanisms in regulated healthcare environments

Integrate automated tests into CI/CD pipelines and monitor automated quality gates

Investigate, document, and track defects; verify fixes and perform regression testing across the full application stack

Validate deployments, perform smoke testing, and support production issue investigation

Ensure testing practices align with healthcare security, privacy, compliance, and data protection requirements

Collaborate closely with software developers, architects, and DevOps teams to improve product quality and testability

Required Qualifications

7+ years of professional experience in software QA, test automation, software development, or Software Development Engineer in Test (SDET) roles

Strong development or automation background may compensate for years of experience

Strong scripting and automation skills using Python, PowerShell, JavaScript, or similar languages

Solid understanding of C#/.NET and modern backend development principles

Experience testing RESTful APIs, backend services, distributed systems, and asynchronous workflows

Hands-on experience validating real-time communication systems such as SignalR or equivalent technologies

Strong understanding of concurrency, asynchronous processing, and race condition validation

Familiarity with SQL Server, Postgres, relational data modeling, and backend data validation

Experience testing cloud-hosted applications, microservices, or distributed systems (AWS preferred)

Understanding of secure application development and testing practices

Experience with Git and modern team-based development workflows

Ability to write clear and maintainable test cases, test plans, automation scripts, and defect reports

Strong analytical, debugging, and troubleshooting skills across backend and distributed systems

Familiarity with MudBlazor or FluentUI component libraries

Experience with performance and load testing tools such as JMeter or k6

Experience testing containerized applications and Docker-based deployments

Familiarity with ORM-based backend systems such as Entity Framework

Knowledge of logging, monitoring, observability, and audit trail validation in regulated environments

Experience with AWS-based healthcare systems or cloud-native architectures

Experience in medical imaging or healthcare applications

Familiarity with DICOM concepts including Study, Series, and SOP Instances

Experience validating integrations with PACS or imaging storage systems

Desired Attributes

Strong attention to reliability, scalability, workflow correctness, and data integrity

Ability to validate complex distributed systems and compliance-sensitive applications

Strong technical mindset with software development and automation-oriented thinking

Ability to troubleshoot across UI, backend services, databases, cloud systems, and distributed workflows
