Quality Assurance Engineer

DOMA Technologies is focused on data-centric transformation in healthcare, elevating health outcomes through quality data-driven solutions. As a Quality Assurance Engineer, you will own the design and execution of testing strategies for full-stack applications, ensuring software reliability and compliance for federal and commercial health clients.

Responsibilities:

• Design, develop, and maintain comprehensive test plans, test cases, and test suites covering functional, regression, integration, performance, and security testing for .NET and React applications
• Execute manual and automated tests against RESTful APIs, front-end components, and back-end services; document and triage defects with reproducible steps and clear severity classifications
• Build and maintain automated test frameworks using tools such as Selenium, Playwright, Cypress, or equivalent; integrate automated test execution into CI/CD pipelines
• Validate AWS-hosted and serverless application deployments, including regression testing post-deployment across staging and production environments
• Conduct API-level testing using tools such as Postman, RestAssured, or SoapUI to validate contracts, error handling, and data integrity between front-end and back-end systems
• Develop and execute performance and load tests to validate system behavior under expected and peak conditions; identify bottlenecks and work with engineers to remediate
• Ensure compliance testing coverage against HIPAA, NIST, and healthcare regulatory standards; validate data handling, access controls, and audit logging meet contractual and regulatory requirements
• Partner with Full-Stack Engineers during development to shift testing left — reviewing requirements, providing testability feedback on designs, and pairing on unit and integration test coverage
• Support and expand test coverage for document management and OCR-integrated workflows, validating data extraction accuracy and downstream processing integrity
• Maintain clear, up-to-date test documentation including traceability matrices, test reports, and defect logs; communicate test status and quality risk clearly to technical and non-technical stakeholders
• Participate in code reviews with a quality lens, flagging missing test coverage, error handling gaps, and security risks
• Contribute to the team’s quality culture by establishing testing standards, improving testing processes, and mentoring engineers on testing best practices
• Stay current with industry trends in test engineering, automation tooling, and quality assurance methodology

Requirements:

• 3+ years of experience in software test engineering, QA engineering, or a closely related role with demonstrated ownership of test strategy and execution
• Proficiency in automated testing frameworks and tools applicable to .NET/C# and React environments (e.g., xUnit, NUnit, MSTest for backend; Jest, React Testing Library, Cypress, or Playwright for frontend)
• Hands-on experience with API testing, including REST API validation, response schema verification, and error condition coverage
• Experience integrating automated tests into CI/CD pipelines (e.g., GitHub Actions, Azure DevOps, Jenkins, or equivalent)
• Solid understanding of test design techniques including boundary value analysis, equivalence partitioning, and exploratory testing
• Experience with performance and load testing tools (e.g., JMeter, k6, Locust, or equivalent)
• Experience working with cloud-hosted applications; familiarity with AWS service behaviors and how deployment architecture affects testability
• Working knowledge of relational and/or NoSQL database testing, including writing queries to validate data integrity
• Experience with version control systems (Git-based) and collaborative development workflows
• Strong analytical and problem-solving skills with meticulous attention to detail
• Clear written and verbal communication skills; ability to document defects and test results that engineers and non-engineers can act on
• Experience testing in federal health IT environments, or regulated industries with compliance requirements (HIPAA, NIST 800-53, FedRAMP)
• Familiarity with document management systems and OCR workflow testing, including accuracy validation for extracted data
• Experience with security testing concepts (OWASP Top 10, SAST/DAST tooling integration, penetration test support)
• AWS Certifications or demonstrated experience validating AWS-hosted serverless architectures (Lambda, API Gateway, S3, RDS, SNS)
• Exposure to AI/ML model output validation or testing non-deterministic system outputs
• ISTQB certification or equivalent structured quality engineering credential
• Experience with contract or data transformation testing in healthcare interoperability contexts (HL7, FHIR)
